Librarian MCP reference
The MCP server behind Thingy, documented from its own declarations: how one tool registry serves Thingy’s chat, your AI and agents in your browser, and every tool with its parameters and results.
How it works
Thingy is not a chatbot with private powers. He answers from one registry of archive tools in the Librarian (the open-source librarian-thing), each declared once in a published spec. The same registry is open through three doors, so an outside agent gets exactly the tools Thingy uses.
Thingy’s chatAnthropic Messages API agent loop, up to 7 tool turns20 tools, called in-process
MCPClaude, ChatGPT, Claude Code, any client20 tools over OAuth 2.1
WebMCPan agent in your browser18 tools through your Thingy session
argument validation → quota → audited invoker → result renderer
One tool registryone handler and one published spec per tool
Weekly Thing, blog and podcast corpora, the link graph, the photo index
- Thingy’s chat. Claude runs the agent loop through the Anthropic Messages API, with 20 tools bound from the same published specs. Tool results stay whole there, since model context in the loop is cheap, but the loop holds itself to the same argument checks and error records as the outside doors. Guests get the 18 archive-only tools.
- MCP.
https://librarian.thingelstad.com/mcpserves the registry over MCP to any client, behind OAuth 2.1. Results are sized for clients that pay for every byte: compact JSON, cut structurally under 48,000 characters. - WebMCP. While you are signed in, the chat page registers the tools with your browser’s model context and proxies calls to
/api/toolswith your session. It leaves outview_photo,fetch_page: a page agent has its own web access and renders archive images natively.
The parity is structural, not a promise: the doors bind one spec file, run one argument validator, share one audited invoker and one result renderer, and the tests hold Thingy’s system prompt to the bound schemas. Each tool carries two descriptions. The chat binds the one written for Thingy’s app; MCP and WebMCP clients get one written for an agent with no app around it. Each tool entry below shows both.

Connecting
Step-by-step setup for Claude, ChatGPT and Claude Code is on Connect your AI. This is what happens underneath.
https://librarian.thingelstad.com/mcp
Transport. Streamable HTTP, stateless: each POST carries one JSON-RPC message and gets one application/json reply. There are no sessions, no server-sent events and no Mcp-Session-Id; every request stands alone, which is what lets the server run on Lambda.
OAuth 2.1
- A request without a token answers
401withWWW-Authenticate: Bearer resource_metadata="https://librarian.thingelstad.com/.well-known/oauth-protected-resource". - The protected resource metadata (RFC 9728) names the authorization server,
https://librarian.thingelstad.com, whose metadata (RFC 8414) is athttps://librarian.thingelstad.com/.well-known/oauth-authorization-server. - The client registers itself at
https://librarian.thingelstad.com/register(dynamic client registration, RFC 7591). Clients are public, so there is no client secret. The token endpoint takes client_id in the form body, or as HTTP Basic with an empty secret. The offline_access scope is accepted and ignored, because every grant gets a refresh token anyway. - The client opens
https://librarian.thingelstad.com/authorizewith PKCE (S256only). The reader signs in with an emailed six-digit code, the same sign-in Thingy uses; the address must be an active Weekly Thing subscription. Then the reader approves thearchive:readscope, and the redirect carries the RFC 9207issparameter. - The client trades the code at
https://librarian.thingelstad.com/token(grantsauthorization_code,refresh_token) and sends the access token asAuthorization: Beareron every/mcprequest.
| Credential | Lifetime |
|---|---|
| Access token | 1 hour |
| Refresh token | 30 days, rotated on every use |
| Connection (refresh token family) | Until 30 days pass without a refresh; no fixed maximum |
| Membership re-check | Every 9 days, at the next refresh |
| Authorization code | 5 minutes |
| Sign-in in progress | 10 minutes |
| Registered client | 1 year |
Refresh tokens rotate on every use; replaying a rotated token revokes the whole token family. A connection lasts as long as the client keeps refreshing: 30 days without a refresh ends it. There is no fixed maximum. Every 9 days the refresh asks Buttondown again about the email the reader signed in with; a lapsed subscription ends the connection, and if Buttondown cannot answer, the refresh goes ahead and asks again next time. Tokens are stored only as hashes.
Connections and the request log
Each approved client is one connection: one refresh token family, named by the client's registered name. Signed in to Thingy, Profile > MCP connections lists them with when each was connected and last used. Disconnect revokes the family, and the access token stops working on its next request rather than when it expires. Every tool call through /mcp or the WebMCP page tools is recorded against the reader with the connection that made it, its arguments, status, duration and result size; View MCP request log shows the reader's own calls for as long as they are kept.
Budgets and rate limits
Each reader has a daily budget per door, and an hourly rate limit that smooths bursts. Each door has its own pool; one never spends another. Daily pools are UTC days and reset at midnight UTC. Supporting Members get 2× the daily budget.
| Door | Daily budget | Per hour |
|---|---|---|
| MCP (tool calls and resource reads) | 500 (1,000 for Supporting Members) | 300 |
| WebMCP (tool calls) | 200 (400 for Supporting Members) | 120 |
| Thingy chat (turns) | 50 (100 for Supporting Members) | 20 |
| OAuth registration | 20 new clients a day, all clients | 10 per address |
| OAuth token requests | 120 per address |
Arguments are checked before any budget is spent, so a malformed call costs nothing. A spent budget is the JSON-RPC error -32029: Daily tool-call quota reached (500 per day). It resets at midnight UTC.
An exceeded hourly limit is HTTP 429.
Protocol conventions
Versions and capabilities
initialize answers protocol 2025-06-18 and also accepts 2025-03-26; any other requested version gets the default. The server declares:
{
"tools": {
"listChanged": true
},
"resources": {},
"prompts": {}
}
The server is stateless, so it can never deliver a list_changed notification. Instead serverInfo.version is 2.12.0+tools.<fingerprint>: the fingerprint hashes every packaged prompt file, the tool specs included, so it changes whenever the declared tools do, and every tool result repeats it as server_version. When it differs from the version a client cached, re-fetch tools/list before trusting cached parameter schemas. This page documents server 2.12.0.
The server’s instructions, sent with initialize:
Tools for exploring Jamie Thingelstad's public archive: The Weekly Thing newsletter, the thingelstad.com blog, the Another Thing podcast, and Things I've built, the registry of Jamie's projects at thingelstad.xyz, plus Linking Things, every public link Jamie has saved. Start broad withsearch_archive, then deepen withget_source; usearchive_lensfor how-things-changed-over-time questions,compare_erasfor then-versus-now,on_this_dayfor this date in every year (this one included),list_topicsfor the topic catalogue,latest_contentfor freshness, andcorpus_statsfor what the archive contains. voice: "jamie" (search_archive,quote_search,find_evidence,compare_erasandarchive_lens) keeps only Jamie's own words, never passages Jamie quoted. year is shorthand for year_range [year, year]. When a result is cut, its truncated block says what was left out and how to get the rest. Sources have one id everywhere (wt-351, blog-<microblog id>, page-<page id>, ep-<n>, thing-<thing id>, doc-<name>, link-<id>); pass it back toget_sourceorsource_neighborhood. Cite each source as a markdown link to its url: [WT351](url) for a Weekly Thing issue, the title for a blog post, page or episode. Pages (About, Lists, Collections, Open Loop) are undated: date-anchored tools leave them out, and updated is their last edit. A thing (thing-<id>; thing-index lists them all) is undated too: its status is Jamie's decision and its started/ended dates are the facts, so cite its page by title. Site pages, the FAQ, things, pages and the reference documents about Jamie (doc-<name>: a bio, a resume; cite by title) are a reference base every search consults whatever the scope or source_kind; no source_kind selects it. A document's document_source and document_date say where it came from and when it was written: say so when you use it. Saved links (link-<id>) are read only when a call names source_kind link (search_archive,find_evidence,quote_search,list_content,latest_content,on_this_day,corpus_stats,compare_eras,archive_lens); no default reads them. Cite a saved link by its title, linked to its url (its Linking Things page). Its title and excerpts are the saved page's words; only a note with note_voice jamie (or the jamie spans of a mixed one) is Jamie's. Photos:media_searchfinds them;view_photoshows up to 3 inline and gives you vision over them. Resources: librarian://wt/{n}, librarian://blog/{id}, librarian://page/{id} and librarian://link/{id} attach one source as markdown; topic, year and on-this-day templates too. Prompts (thinking_over_time, year_in_review, reading_path, this_week_in_past_years, research_brief) set out the call sequence for the big asks. The tool schemas evolve; serverInfo.version changes whenever they do - if it differs from your cached value, re-fetch tools/list before relying on cached parameter schemas.
One id everywhere
Every source has one id, the same in every tool: wt-351 for a Weekly Thing issue, blog-<microblog id> for a blog post, ep-<n> for a podcast episode. Whatever a tool returns, get_source and source_neighborhood accept. Every url in a result is absolute, so a client can cite with a markdown link: [WT351](url) for an issue, the title for a post or episode.
The applied echo
Every result starts with applied: the arguments the server actually used after defaults and normalisation (the window, the limit, the voice, the offset). An agent can check it rather than assume its arguments landed as meant.
Paging and truncation
A tool that lists takes limit (each has its own range and default, below) and offset, returns one fixed order named in its description, and reports total_count for the whole list. Anything left out is described in one truncated block, never in inline markers. For example:
"truncated": {
"omitted": { "results": 12 },
"clipped": ["results[].passages[].text"],
"max_chars": 48000,
"next_offset": 20,
"hint": "Cut to fit 48000 characters at 20 results; call again with offset 20 for the rest."
}
The outside doors cap a result at 48,000 characters. The cut is structural, so the JSON always parses: whole items come off the end of the largest list first (results are ranked, so the weakest go), then the longest text is clipped. When the paged list is the one cut, next_offset moves back to the first item cut, so paging stays exact. A result that cannot fit even then is a too_large error naming the arguments to narrow.
| Tool | Paged list |
|---|---|
archive_lens | results |
currently_history | entries |
find_links | results |
latest_content | results |
list_content | results |
list_topics | topics |
media_search | results |
on_this_day | years[].items |
quote_search | results |
search_faq | results |
top_references | top |
Typed results
Every tool declares an outputSchema, and a successful call carries the result twice: as structuredContent for clients that read it, and as compact JSON text in content for those that do not. Every tool is annotated readOnlyHint: true; openWorldHint is true only for fetch_page, the tools that reach the live web.
Errors
A tool that cannot answer returns a normal result with isError: true, one code from a closed set, and one next step the agent can act on. Error results carry no structuredContent.
| code | next |
|---|---|
bad_request | Check the arguments against this tool's input schema and call it again. |
not_found | Find a valid id with search_archive, list_content or latest_content, then call again. |
not_configured | This deployment does not offer that; use the archive tools instead. |
upstream_error | The outside service failed; try again later or answer from the archive. |
too_large | Narrow the arguments and call again. |
internal_error | Try again; if it keeps failing, answer from another tool. |
Arguments are validated against the declared schema before any budget is spent. Every schema says additionalProperties: false, and the validator means it: an undeclared argument, a value outside its enum or range, text past its length, an inverted year_range, or year and year_range together is a bad_request that names every problem and lists the accepted arguments. Scalars are accepted in either spelling a client might send ("12" for 12).
{
"error": "Invalid arguments for search_archive: unknown argument \"q\"; query is required.",
"code": "bad_request",
"accepted_arguments": [
"query",
"year_range",
"year",
"section",
"section_family",
"content_kind",
"voice",
"source_kind",
"topic",
"category",
"limit"
],
"next": "Check the arguments against this tool's input schema and call it again."
}
Protocol-level failures are JSON-RPC errors:

Voice
A Weekly Thing passage mixes Jamie’s commentary with quotations from the linked author and link titles. Every passage is tagged by voice, and search_archive, quote_search, archive_lens, compare_eras, find_evidence take voice: jamie keeps only Jamie’s own words, quoted the passages Jamie quoted, link the headline link titles. Passages are cut to that voice before ranking. Thingy’s own bylined blocks in recent issues never enter the archive at all.
Years
Windows are year_range: [start, end] everywhere; year is shorthand for [year, year]. Pass one or the other. Tools that take a window: search_archive, list_content, find_links, corpus_stats, quote_search, archive_lens, archive_gems, media_search, currently_history, top_references, on_this_day.
Retired tools
A client holding an old tools/list may still call a tool that was folded into another. It gets an error result that names the replacement, not Unknown tool:
| Retired | Answer |
|---|---|
entity_lens | entity_lens was folded into archive_lens in 2.0.0: call archive_lens with topic, and aliases for other names (known aliases are added for you). Re-fetch tools/list. |
claim_check | claim_check became find_evidence in 2.0.0: pass claims (one to four statements); it returns the passages for each, and the verdict is yours. Re-fetch tools/list. |
Tools
20 tools, as tools/list declares them. Every one reads; none writes.
Search and read
Find passages by meaning or exact words, read a source whole, and gather evidence for claims.
Search the archive search_archive
read-only closed world: archive only MCP WebMCP Thingy chat guest chat
Search the whole archive (Weekly Thing, blog, podcast) by meaning and exact terms. The reference base (site pages, the FAQ, things, pages and documents about Jamie such as a bio) is searched every time; no source_kind selects or leaves it out. A document's passages carry document_source and document_date: where it came from and when it was written. Results are grouped by source, best first: the source's id, label, date, url and skim, then its matching passages. Narrow with year_range, section_family, content_kind, voice, topic (a list_topics cluster) or category (blog). A ranked top-N that does not page: quote_search lists every literal match, archive_lens counts completely.
Parameters
| Parameter | Type | Constraints | Description |
|---|---|---|---|
query required |
string |
What to find, in natural language or keywords; ranked by meaning and by exact terms. | |
year_range |
integer[2] |
each 1990 to 2100 | [start_year, end_year]; the same year twice for one year. |
year |
integer |
1990 to 2100 | One year: shorthand for year_range [year, year]. |
section |
string |
A Weekly Thing section heading or family, e.g. "Journal". A group heading from the body ("Notable Links 📌", "Stream", "Now Reading 📚") takes every passage under it; a name that is a heading or family exactly matches only that ("coffee" is Coffee, not Coffee Gear); any other name matches inside headings; a name that matches nothing is an error. | |
section_family |
string |
A Weekly Thing section family, matched exactly across every era's renames: Featured, Notable, Briefly, FYI, Journal, Currently, Photo, Fortune, Reply All, Straw Poll, Give Back, App, Yearly Thing. | |
content_kind |
string |
one of links, personal, essay, meta, reference, blog, podcast_transcript, podcast_notes |
links (link sections), personal (Journal, Currently, Photo), essay, meta (Fortune, Reply All, polls), reference, blog, podcast_transcript, podcast_notes. |
voice |
string |
one of jamie, quoted, link |
Whose words: jamie (Jamie's own), quoted (passages Jamie quoted), link (headline link titles). Passages are cut to that voice. A voice=jamie passage left with under 40 characters of Jamie's words is dropped. |
source_kind |
string |
one of weekly_thing, blog, podcast, link |
Only this source. link is the links Jamie saved on Linking Things: read only when named, and then alone. |
topic |
string |
A list_topics cluster, e.g. "AI and agents". A Weekly Thing passage matches when its issue is filed under the cluster or the passage itself is labelled with it; blog and podcast passages match by their own labels (many blog passages and some podcast passages carry one). |
|
category |
string |
A blog category, e.g. "Coffee", "Kubb", "Family"; blog only. | |
limit |
integer |
1 to 12; default 8 |
Most passages, 1 to 12 (default 8). |
Returns
querystring, optionalresultsarray: Sources, best first, each with passages (a passage from an issue with an audio edition carries audio {url, start, chapter}).notestring, optional: Says the list is ranked, not every match, and where the complete answers are.
Plus the envelope every tool carries: applied, truncated when something was cut, and server_version.
What Thingy is told in chat
The chat loop binds the same schema with the description written for Thingy’s app:
Hybrid search over the active archive source scope: Weekly Thing, blog, podcast, or any enabled combination, always with the reference base (site pages, the FAQ, Things I've built, thingelstad.com's pages and reference documents about Jamie such as a bio), which no scope or source_kind leaves out and which, being undated, no year_range keeps. A reference document's passages are its H2 sections and carry document_source and document_date, where the document came from and when it was first written: say so when you use one ("from Jamie's 2011 wiki"). source_kind link searches the links Jamie saved on Linking Things (links.thingelstad.xyz) instead, which no other call reads: link-<id>, one passage each, dated the Chicago day it was saved, carrying link_url (the page it saved), host, link_type, tags, note_voice and shared_in_issues. Cite one by its title. Its title and excerpts are the saved page's words; only a note whose note_voice is jamie (or the jamie spans of a mixed one) is Jamie's. topic does not apply to saved links. Default first stop for broad topics, themes, and evidence gathering. Use iteratively when needed: refine query, year_range, section, section_family, content_kind, voice, topic or category based on what comes back. Results are grouped by source, best first: each carries its source's id, facts and skim (the issue's description, the post's abstract; a generated abstract says so) once, then its matching passages. A passage longer than 2,000 characters shows the stretch where the query's words gather, and clipped gives {start, end, chars};get_sourcereads it whole. A Weekly Thing Journal passage is a copy of blog posts: copy_of names each post, which is canonical, and the post wins when both match. A passage from an issue with an audio edition carries audio {url, start, chapter}: its section's chapter, the url starting there. An unknown topic or category is an error that lists the valid ones. year_range is [start_year, end_year]; year is one year. voice=jamie keeps only Jamie's own words (quotations and link titles are cut from each passage), and drops a passage left with under 40 characters of them, so a quotation with a line of framing does not rank as Jamie's writing (archive_lenshas no floor: it filters, it does not rank). This is a ranked top-N, not every match, and it does not page:quote_searchlists every literal match, andarchive_lenscounts completely. URLs in results are citation metadata for the app; do not quote or narrate raw URLs/paths in the answer.

}Read a source get_source
read-only closed world: archive only MCP WebMCP Thingy chat guest chat
Read one source whole: a Weekly Thing issue, blog post or podcast episode, by the id other tools return. format outline gives the facts, skim and section names; text adds the body; full (default) adds the links. section reads one section. A reference document (doc-<name>) carries document_source and document_date, where it came from and when it was written. An issue's audio edition is audio_url, audio_duration_seconds and audio_chapters; with section, section_audio starts its chapter. readers carries what Tinylytics counted (views, an issue's email opens and feed reads, kudos) since the site was first counted, never all time.
Parameters
| Parameter | Type | Constraints | Description |
|---|---|---|---|
id required |
string |
The source id other tools return: wt-351, blog-<microblog id>, page-<page id>, ep-<n>, doc-<name> for a reference document, link-<id> for a saved link. WT351, a bare issue number or the source's url also work. | |
section |
string |
One section: a heading (any heading in the body, an H2 group or an H3 inside a post), a substring of one, or a family (Issue, Notable, Briefly, Journal, Currently, Fortune). An exact name or family wins over a substring. Notable returns its articles; recent Journals split by day. | |
format |
string |
one of outline, text, full; default "full" |
outline: facts, skim, sections and link counts; text: plus the body; full (default): plus the links. |

What Thingy is told in chat
The chat loop binds the same schema with the description written for Thingy’s app:
Fetch full context for one known archive source in the active scope: a Weekly Thing issue, blog post/micropost, thingelstad.com page, or podcast episode, or a link Jamie saved on Linking Things. Use aftersearch_archive,list_content,archive_lens,archive_gems,find_linksorsource_neighborhoodidentifies a specific source worth reading more deeply. Identify it by id as other tools emit it (wt-351, blog-<microblog id>, page-<page id>, ep-<n>, doc-<name> for a reference document about Jamie, link-<id> for a saved link whatever the scope (its links.thingelstad.xyz/links/<id>/ url too); WT351, a bare issue number or the source's url also work). Optional section narrows the returned text; format outline skips the body and links, text skips the links. body is the source's full text and sections lists its section names and word counts; a body longer than one result is cut and named in truncated, whose next_offset reads the rest; section reads one section or heading (an exact name wins), and a name that matches nothing is an error listing available_sections. A reference document carries document_source and document_date (where it came from, when it was first written: cite them, "from Jamie's 2011 wiki"), and its sections are its H2 headings. A saved link carries link_url (the page it saved), host, link_type, tags, its note, note_voice (jamie, excerpt: the saved page's words, or mixed) and shared_in_issues; cite it by its title. A Weekly Thing issue with an audio edition carries audio_url, audio_duration_seconds and audio_chapters [{start, title}]; with section, section_audio {url, start, chapter} starts that section's chapter. readers is what Tinylytics counted for the source: views (count, last_30_days, prior_30_days, trend rising/falling/steady/new, by_month), an issue's email_opens and feed_reads, and kudos {count, days}; counted since tracked_since (www since July 2024, the other sites since 2026), never all time, so say since when. Email opens are per issue, never per reader. URLs in results are citation metadata for the app; do not quote or narrate raw URLs/paths in the answer.

What Thingy is told in chat
The chat loop binds the same schema with the description written for Thingy’s app:
Find the archive evidence for one to four draft claims. Use sparingly before finalizing an answer that hinges on specific facts, dates, counts or source relationships. For each claim it returns the best passages with their source id and voices (whose words each passage holds: jamie, quoted, link). It makes no verdict: read the passages and decide whether they support the claim; a passage whose voices include quoted may be someone else's words. source_kind link looks among the links Jamie saved on Linking Things (links.thingelstad.xyz) instead, which no other call reads; a saved link's link and quoted voices are not Jamie's. A passage longer than 450 characters shows the stretch where the claim's words gather, and clipped gives {start, end, chars}; copy_of on a Weekly Thing Journal passage names the canonical blog post; audio {url, start, chapter} on a passage from an issue with an audio edition starts its section's chapter.

Topic history archive_lens
read-only closed world: archive only MCP WebMCP Thingy chat guest chat
Trace a topic, person, product or idea across the whole archive: counts by year, first and latest mention, a timeline, year and source buckets, evidence spans and a reading path. operation picks what results holds. aliases adds other names; known ones are added for you. Each source is in sources_by_id once; lists hold its id.
Parameters
| Parameter | Type | Constraints | Description |
|---|---|---|---|
topic required |
string |
up to 200 characters | The topic, person, product or idea. Matched whole in subjects, text and linked domains; a list_topics cluster name matches only when named whole. |
aliases |
string[] |
at most 8 items; each up to 200 characters | Other names for the same thing, e.g. ["Ethereum Name Service"] for ENS. Known aliases are added for you. |
operation |
string |
one of timeline, first_last, by_year, source_compare, reading_path; default "timeline" |
What results holds: timeline (default), first_last, by_year, source_compare or reading_path. |

What Thingy is told in chat
The chat loop binds the same schema with the description written for Thingy’s app:
Build a deterministic Archive Lens over the active source scope for one topic, or one named person, project, product, place, organization or recurring idea (aliases adds other names for it; known ones such as Ethereum Name Service for ENS are added automatically and reported as aliases_checked). Use for genuinely analytical questions: timelines, first/latest mentions, year-by-year topic/theme slices, source comparisons across Weekly Thing/blog/podcast, and reading paths through a theme. It scans corpus metadata and matching chunks, then returns counts_by_year, first/latest sources, year buckets, source buckets, timeline entries, representative evidence snippets, match reasons, and a suggested reading_path. operation can be "timeline", "first_last", "by_year", "source_compare", or "reading_path". Optional source_kind isolates "weekly_thing", "blog", or "podcast", or names "link": the links Jamie saved on Linking Things (links.thingelstad.xyz), by the year each was saved, which no other call reads. year_range is [start_year, end_year]; year is one year. Use this before semantic search when the user asks how a topic evolved or how attention changed over time. URLs in results are citation metadata for the app; do not quote or narrate raw URLs/paths in the answer. Response shape: sources_by_id holds each full source record once, keyed by id (wt-300, blog-987, ep-4); first/latest/results/timeline/latest_sources and sample_sources reference those ids (with operation timeline, results is the timeline) - resolve details by id, and evidence entries carry the matched span that proves the hit. Matching is whole-token/phrase based (see match_mode); match_reasons and evidence attribute the exact span found. If the response carries term_frequency_note, the term is too common to rank meaningfully - reformulate instead of trusting first/latest. match_reasons list every matched case/inflection variant of the term.

What Thingy is told in chat
The chat loop binds the same schema with the description written for Thingy’s app:
Compare how a topic shows up in two eras of the archive: the best passages for the same topic from year_a and from year_b, side by side. Use for "how did Jamie's view of X change between 2018 and 2025". year_a and year_b are each [start_year, end_year]. source_kind link compares the links Jamie saved on Linking Things (links.thingelstad.xyz) in each era instead, which no other call reads. voice=jamie keeps only Jamie's own words. era_a and era_b say how many sources each era published and how many name the topic, with a note when an era has none or never names it. URLs in results are citation metadata for the app; do not quote or narrate raw URLs/paths in the answer.

date |
string |
YYYY-MM-DD or MM-DD (default today in America/Chicago). That year and every earlier year are returned. | |
window_days |
integer |
0 to 7; default 0 |
Days either side of the date to include, 0 to 7 (default 0). |
year_range |
integer[2] |
each 1990 to 2100 | [start_year, end_year] of publication; the same year twice for one year. With window_days, a source keeps its own publish year even when it sits under the next year's anniversary. |
year |
integer |
1990 to 2100 | One publish year: shorthand for year_range [year, year]. |
source_kind |
string |
one of weekly_thing, blog, podcast, link |
Only this source. link is the links Jamie saved on Linking Things: read only when named, and then alone. |
include_microposts |
boolean |
default true |
Include blog microposts (default true). |
limit_per_year |
integer |
1 to 20; default 5 |
Maximum items per year, 1 to 20 (default 5, or 2 when window_days is set). Each year's total_count holds its full number; truncated.omitted['years[].items'] counts what was cut and next_offset pages on. |
offset |
integer |
at least 0; default 0 |
Skip this many items in every year before the first one returned (default 0). A cut list's truncated.next_offset is the value for the next page. |
Returns
total_countinteger, optionalyearsarray: {year, years_ago, total_count, items}
Plus the envelope every tool carries: applied, truncated when something was cut, and server_version.
Pages years[].items with limit and offset; a cut page says where the next starts in truncated.next_offset.
What Thingy is told in chat
The chat loop binds the same schema with the description written for Thingy’s app:
What Jamie published on this calendar day, in the date's own year and every year before, across the Weekly Thing, the blog and the podcast: the archive's "on this day". source_kind link lists the links Jamie saved on Linking Things (links.thingelstad.xyz) on that day instead, which no other call reads, each excerpt its note. Defaults to today in America/Chicago. A source's day is its Chicago date (a Weekly Thing issue's send time, a blog post's published time); Feb 29 folds into Feb 28 in a year without one and is its own day in a year with one. Returns years newest first (years_ago 0 is the date's own year), each year's items in the order issue, episode, blog posts by Chicago time of day (microposts after the other posts; a post with no time last), each with years_ago and items {id, label, source_kind, title, date, url, excerpt, photo?}; read one withget_source(id), show a photo withview_photo. Use for anniversaries, "what was Jamie writing a year ago", and daily look-backs. URLs in results are citation metadata for the app; do not quote or narrate raw URLs/paths in the answer.

read-only closed world: archive only MCP WebMCP Thingy chat guest chat
The links Jamie shared: by domain (with subdomains), by url ("has Jamie linked this before"), by topic, link_role (the headline pick, commentary or journal), source_kind and year_range. Newest first; each result names its source id. With no filters, the most-linked domains.
Parameters
| Parameter | Type | Constraints | Description |
|---|---|---|---|
id |
string |
Only the links in one source (wt-274, blog-<microblog id>, page-<page id>, ep-<n>), in the order the source carries them; page with offset. A saved link's id, link-<id>, lists the Weekly Thing and blog links that are it or link its page. | |
domain |
string |
A linked domain; its subdomains count too (netflix.com includes media.netflix.com). | |
url |
string |
One page, however it was spelled when linked: every time it was linked. | |
topic |
string |
up to 200 characters | A word or phrase matched in each link's text, title, heading, context or domain. |
source_kind |
string |
one of weekly_thing, blog, podcast |
Only this source. A saved link (Linking Things) carries no links of its own: find_links with id link-<id> lists the Weekly Thing and blog links that are one. |
link_role |
string |
one of headline, commentary, journal |
Weekly Thing links: headline (the pick), commentary (a link in what Jamie wrote about it) or journal. |
link_kind |
string |
one of external, internal |
external or internal links. |
link_category |
string |
one of external, cross_source, resolved_post, collection_page, upload_asset, malformed_internal, internal_unresolved, internal_site |
cross_source links Jamie's own sites to each other (blog to Weekly Thing, podcast to blog). |
target_resolved |
boolean |
Links to Jamie's own sites only: true keeps those that resolved to a known post or issue, false those that did not. External links match neither. | |
year_range |
integer[2] |
each 1990 to 2100 | [start_year, end_year]; the same year twice for one year. |
year |
integer |
1990 to 2100 | One year: shorthand for year_range [year, year]. |
limit |
integer |
1 to 50; default 20 |
Most results, 1 to 50 (default 20). |
offset |
integer |
at least 0; default 0 |
Skip this many before the first one returned (default 0), to page through the whole list in the order above. A cut list's truncated.next_offset is the value for the next page. |
sort |
string |
one of newest, oldest; default "newest" |
newest first (default) or oldest first, before limit applies. With id the links keep the source's own order and applied.sort says source_order. |
match_mode |
string |
one of exact, phrase, stem |
exact (default): whole words, a contiguous phrase for several; stem: inflections too (plurals only under 6 letters; ethereum never matches ethernet). |
case_sensitive |
boolean |
Match case: topic "Go" finds the language, never "to go". Default false. |
Returns

What Thingy is told in chat
The chat loop binds the same schema with the description written for Thingy’s app:
Query link metadata in the active source scope by source (id: every link in one issue, post, page or episode), domain, topic, source_kind, link_kind, link_category, target_resolved, and year range. source_kind can be "weekly_thing", "blog", or "podcast" and lets you isolate one corpus even when the active scope is all. link_kind can be "external" or "internal". link_category includes "external", "cross_source", "resolved_post", "collection_page", "upload_asset", "malformed_internal", "internal_unresolved", and "internal_site". cross_source means a link between Jamie-owned corpora such as blog to Weekly Thing or podcast to blog. target_resolved applies to links to Jamie's own sites only: true keeps those that resolved to a known post or issue, false those that did not; an external link matches neither. Does not fetch linked pages. Call with url to ask "has Jamie linked this before" (matched however the link was spelled: scheme, www, trailing slash, fragment and tracking parameters such as utm_*, ref, fbclid and smid ignored). link_role narrows Weekly Thing links: headline (the pick a link section is built from), commentary (a link inside what Jamie wrote about it) or journal (a link in the Journal). Call with domain for domain history (the domain and its subdomains); call without filters for top external domains, ranked by editorial picks (Weekly Thing headline links; source_kind blog ranks blog links) (the 20 most linked; truncated.omitted.top_domains counts the rest, andtop_referencespages through them all). year_range is [start_year, end_year]; year is one year. Results are newest first (sort: "oldest" reverses); page with offset, and truncated.next_offset names the next page. Each result's id is its source, forget_source. A link that is a link Jamie saved on Linking Things, or links its page there, names it as saved_link (link-<id>, forget_source); id link-<id> lists those links. URLs in results are citation metadata for the app; do not quote or narrate raw URLs/paths in the answer. Matching is whole-token/phrase based (see match_mode); match_reasons name the exact span found. Links on undated thingelstad.com pages sort last; undated_count says how many are in total_count but in no year.

The domains Jamie picks most (Weekly Thing headline links, by host; source_kind blog ranks blog links), with counts by year, first and last seen, and sample titles. Every link left out in the window is counted: Jamie's own sites, commentary and Journal links, blog and podcast links, and utility sites unless include_utility. Ranked by count; page with offset. A domain often stands for a person (daringfireball.net is John Gruber).
Parameters
| Parameter | Type | Constraints | Description |
|---|---|---|---|
year_range |
integer[2] |
each 1990 to 2100 | [start_year, end_year]; the same year twice for one year. |
year |
integer |
1990 to 2100 | One year: shorthand for year_range [year, year]. |
limit |
integer |
1 to 40; default 20 |
Most domains, 1 to 40 (default 20). |
offset |
integer |
at least 0; default 0 |
Skip this many before the first one returned (default 0), to page through the whole list in the order above. A cut list's truncated.next_offset is the value for the next page. |
include_utility |
boolean |
Count utility and social sites too (utility_domains: each its own host only, www, m. and mobile. aside, except wikipedia.org with its language editions; aws.amazon.com is not amazon.com); left out by default. | |
source_kind |
string |
one of weekly_thing, blog, podcast |
Only this source. Pass weekly_thing for the newsletter so older blog links do not count. |

What Thingy is told in chat
The chat loop binds the same schema with the description written for Thingy’s app:
Who and what Jamie links to most: his editorial picks (Weekly Thing headline links in Notable, Briefly and the like), aggregated by exact host (www merged; subdomains are their own rows), with total counts, per-year counts, first/last seen, and sample titles. Left out, and counted in the same window: Jamie's own sites (excluded_internal_links), links in Weekly Thing commentary or the Journal (excluded_non_headline_links), blog and podcast links, which connect rather than recommend (excluded_blog_and_podcast_links; source_kind blog ranks blog links instead), and utility sites unless include_utility (excluded_utility_links: wikipedia.org with its language editions, and only the host itself, www, m. and mobile. aside, for linkedin.com, twitter.com, x.com, instagram.com, facebook.com, poap.gallery, poap.xyz, poap.delivery, collectors.poap.xyz, app.poap.xyz, amazon.com, micro.blog; any other subdomain is its own site and counts, so aws.amazon.com and other people's *.micro.blog blogs rank). Ranked by count, ties by domain; page with offset. Use FIRST for 'who does Jamie reference/cite most', 'favorite sources', or 'most-linked sites' - then find_links with domain for every link to one of them (subdomains, commentary and blog links included, so its count can be higher). Domains map to people (daringfireball.net is John Gruber, stratechery.com is Ben Thompson). URLs in results are citation metadata for the app; do not quote or narrate raw URLs/paths in the answer.The declaration, as tools/list sends it

What Thingy is told in chat
The chat loop binds the same schema with the description written for Thingy’s app:
Explore what connects to one known archive source. Given a source id (wt-351, blog-<microblog id>, page-<page id>, ep-<n>, link-<id>, as other tools emit it), return outgoing links, incoming links when known (outgoing_count and incoming_count say how many there are; up to 30 of each are listed;find_linkswith id pages through every link in a source, andfind_linkswith url lists every link to it; each link names its source id) (an entry with link_category cross_source links Jamie's corpora to each other; cross_source_count totals them), similar issues by meaning (for an issue), similar posts by meaning (for a blog post: its nearest other posts, leaving out posts from the same trip and taking at most one from each other trip, each with a score that ranks within this list only), and related sources (related means sharing at least 3 distinctive terms: words of five or more letters from the title and opening, or domains it linked as picks, each used by fewer than max(2% of the sources in scope, 20) sources; related_count counts them all, related_sources lists the top limit). Use for connected-archive questions like "what else is near this?", "where did this link lead?", "did this blog post connect to Weekly Thing?", or to build rabbit-hole style follow-ups. A saved link (link-<id>) is read whatever the scope: its incoming links are the issue and post links that are it or link its page, and its related sources include other saved links. URLs in results are citation metadata for the app; do not quote or narrate raw URLs/paths in the answer.

List and count sources deterministically: by source_kind, year_range, topic, linked domain, link kind or category, blog posts an issue reprinted (also_in_issue) or linked (linked_from_issue), and issues with an audio edition (has_audio; each carries audio_url and audio_duration_seconds). sort most_read, most_read_30d, most_read_90d, most_kudos or rising orders by what Tinylytics counted, never all time. For how-many and which-ones questions; search_archive is for relevance.
Parameters
| Parameter | Type | Constraints | Description |
|---|---|---|---|
source_kind |
string |
one of weekly_thing, blog, podcast, link |
Only this source. link is the links Jamie saved on Linking Things: read only when named, and then alone. |
year_range |
integer[2] |
each 1990 to 2100 | [start_year, end_year]; the same year twice for one year. |
year |
integer |
1990 to 2100 | One year: shorthand for year_range [year, year]. |
topic |
string |
up to 200 characters | A word or phrase matched whole in subjects, text and linked domains; a list_topics cluster name matches only when named whole. |
aliases |
string[] |
at most 8 items; each up to 200 characters | Other names for the same thing, e.g. ["Ethereum Name Service"] for ENS. Known aliases are added for you. |
domain |
string |
A linked domain; its subdomains count too. | |
link_kind |
string |
one of external, internal |
external or internal links. |
link_category |
string |
one of external, cross_source, resolved_post, collection_page, upload_asset, malformed_internal, internal_unresolved, internal_site |
cross_source links Jamie's own sites to each other (blog to Weekly Thing, podcast to blog). |
target_resolved |
boolean |
Links to Jamie's own sites only: true keeps those that resolved to a known post or issue, false those that did not. External links match neither. | |
has_also_in_issues |
boolean |
Blog posts: true keeps posts a Weekly Thing issue reprinted (its Journal carried the post), false those none did. | |
has_linked_from_issues |
boolean |
Blog posts: true keeps posts a Weekly Thing issue linked without reprinting (a pick, a link in prose, a Journal link to an older post), false those none did. | |
has_audio |
boolean |
Weekly Thing issues: true keeps issues with an audio edition (a spoken reading with chapters, WT180 on), false those without. Keeps issues only; not with source_kind blog or podcast, nor with the also_in_issues or linked_from_issues filters. | |
also_in_issue |
integer |
Blog posts this Weekly Thing issue number reprinted. | |
linked_from_issue |
integer |
Blog posts this Weekly Thing issue number linked without reprinting. | |
limit |
integer |
1 to 120; default 40 |
Most results, 1 to 120 (default 40). |
offset |
integer |
at least 0; default 0 |
Skip this many before the first one returned (default 0), to page through the whole list in the order above. A cut list's truncated.next_offset is the value for the next page. |
match_mode |
string |
one of exact, phrase, stem |
exact (default): whole words, a contiguous phrase for several; stem: inflections too (plurals only under 6 letters; ethereum never matches ethernet). |
case_sensitive |
boolean |
Match case: topic "Go" finds the language, never "to go". Default false. | |
sort |
string |
one of newest, most_read, most_read_30d, most_read_90d, most_kudos, rising; default "newest" |
newest (default), or by Tinylytics counts: most_read (views since the site was first counted), most_read_30d, most_read_90d, most_kudos, rising (gain in views, last 30 days over the 30 before). Ties keep date order. |
Returns
scopestring, optionalsource_kindstring | null, optionalmatch_modestring | null, optionalaliases_checkedarray, optionaltotal_countintegerundated_countinteger, optional: Sources (list_content) or links (find_links) on undated thingelstad.com pages: in total_count, in no year.counts_by_yeararray, optional: [{<key>, count}]counts_by_sourcearray, optional: [{<key>, count}]readers_countedobject, optional: With a reader sort: {<site host>: {tracked_since, through}}, the US Central days the listed sites' numbers cover.notestring, optional: With a reader sort, says which sources have no numbers yet (or that none do, and the list stayed newest first).resultsarray: Newest first, or in applied.sort's order. On each source, date is the Chicago day it was published (Jamie publishes in Central time); publish_date is the corpus value as stored: a UTC timestamp for an issue, the Chicago day for a blog post, the day for an episode. With a reader sort each carries readers {views, views_last_30_days, views_prior_30_days, views_last_90_days, trend, kudos, email_opens (issues)}.
Plus the envelope every tool carries: applied, truncated when something was cut, and server_version.
Pages results with limit and offset; a cut page says where the next starts in truncated.next_offset.
What Thingy is told in chat
The chat loop binds the same schema with the description written for Thingy’s app:
List source-level metadata across the active scope: Weekly Thing issues, blog posts/microposts/pages, and podcast episodes; source_kind link lists the links Jamie saved on Linking Things (links.thingelstad.xyz) instead, by the year each was saved, which no other call reads. Use for counts and deterministic listings by source_kind, year_range (or year), topic, linked domain, link_kind, link_category, target_resolved, has_also_in_issues, also_in_issue, has_linked_from_issues, linked_from_issue, or has_audio. Prefer this over semantic search for inventory questions like posts by year, which sources mention a domain, which blog posts crossed into Weekly Thing, or which issues have an audio edition. A blog result's also_in_issues names the issues that reprinted it; linked_from_issues the issues that linked it without reprinting it. A Weekly Thing result with an audio edition carries audio_url and audio_duration_seconds. URLs in results are citation metadata for the app; do not quote or narrate raw URLs/paths in the answer. Matching is whole-token/phrase based (see match_mode); match_reasons name the exact span found. Undated thingelstad.com pages list after every dated source; undated_count says how many are in total_count but in no year. sort orders by what readers did instead of by date: most_read (views since counting began), most_read_30d, most_read_90d, most_kudos, or rising (the biggest gain in views, last 30 days over the 30 before; sources from the last 60 days are new and come after); each result then carries readers and readers_counted says since when each site was counted. Reader numbers say what was read, not what matters or what is relevant to a question.

Parameters
| Parameter | Type | Constraints | Description |
|---|---|---|---|
query |
string |
up to 200 characters | Part of a cluster or topic name, e.g. "apple". |
limit |
integer |
1 to 100; default 40 |

integer |
at least 0; default 0 |
Skip this many before the first one returned (default 0), to page through the whole list in the order above. A cut list's truncated.next_offset is the value for the next page. |

}Media
Photos found by what they show, and vision over them.
Search photos media_search
read-only closed world: archive only MCP WebMCP Thingy chat guest chat
Find photos by what they show: every word of query in the alt text, caption, context, a vision description of the image, a blog post's title, or its file name's words (plurals match both ways; a quoted query is a phrase). A word in either copy's description finds a photo a Weekly Thing issue reprinted from the blog; the blog photo is the result, and its also_in_issues names every issue it ran in. match_reasons names the field each word matched. Omit query to list, e.g. one issue's photos. Newest first; page with offset. Returns image_url and the source each appeared in; view_photo shows them to you (viewable: false says it cannot). Embed one as [](source_url).
Parameters
| Parameter | Type | Constraints | Description |
|---|---|---|---|
query |
string |
up to 200 characters | What the image should show, e.g. "bike ride creek" or "cabin winter"; every word must match. Omit to list. |
match_mode |
string |
one of exact, phrase, stem |
stem (default): plurals and inflections both ways, so dog finds dogs and dogs finds dog (irregular plurals such as people are not folded); exact: whole words only; phrase: the whole query as one phrase in one field (a query in double quotes is a phrase too). |
year_range |
integer[2] |
each 1990 to 2100 | [start_year, end_year]; the same year twice for one year. |
year |
integer |
1990 to 2100 | One year: shorthand for year_range [year, year]. |
source_kind |
string |
one of weekly_thing, blog |
Only this source. Another Thing episodes have no photos in the index, so podcast is not a choice. |
issue_number |
integer | string |
at least 1 | One Weekly Thing issue's photos, e.g. 351 or "140-special". Weekly Thing only. |
limit |
integer |
1 to 12; default 8 |
Most results, 1 to 12 (default 8). |
offset |
integer |
at least 0; default 0 |
Skip this many before the first one returned (default 0), to page through the whole list in the order above. A cut list's truncated.next_offset is the value for the next page. |
Returns

What Thingy is told in chat
The chat loop binds the same schema with the description written for Thingy’s app:
Search the photo and image index across the archive by what the images show. Every word of query must appear in the photo's alt text, caption, nearby context, vision-model description of its actual content, a blog post's title, or the words in its file name (strawpoll297.png is found by strawpoll) - so visual queries work even when the caption never names what is shown. Words match whole, accents either way, and plurals both ways by default (dog finds dogs, dogs finds dog); match_mode phrase, or a query in double quotes, matches the words together in one field. Omit query to list photos newest first, e.g. one issue's with issue_number. Results are newest first; page with offset. A Weekly Thing photo that reprints a blog photo folds into the blog photo, which is canonical, and the two copies' vision descriptions count as one photo's: a word in either copy's description finds it (match_reasons names the copy); a blog photo's also_in_issues names every issue it ran in, whatever matched, and collapsed_copies counts the folded copies. With year or year_range a copy also counts in its issue's year when its blog photo is outside the window, so per-year totals can sum a little past the whole listing (note says so); photos on undated pages are in no year. An issue_number not in the archive is not_found. Use for 'show me photos of X', 'pictures from Y', or any question about images Jamie published. Returns direct image URLs plus the source issue or post. Show them as clickable linked thumbnails: [](source_url). Image URLs here are the exception to the no-raw-URL rule: they are meant to be embedded as markdown thumbnails in the answer.

}Reading, playing & watching currently_history
read-only closed world: archive only MCP WebMCP Thingy chat guest chat
What Jamie was reading, watching, playing, listening to, building and more, from every issue's Currently section: dated entries with their issue, counted by kind and year.
Parameters
| Parameter | Type | Constraints | Description |
|---|---|---|---|
kind |
string |
watching, listening, installing, reading, playing, drinking, buying, eating, deleting, using, building, dining, flying, giving, walking or wearing; variants such as "installing more" count as their kind. | |
year_range |
integer[2] |
each 1990 to 2100 | [start_year, end_year]; the same year twice for one year. |
year |
integer |
1990 to 2100 | One year: shorthand for year_range [year, year]. |
query |
string |
up to 200 characters | Part of the entry text. |
limit |
integer |
1 to 120; default 40 |
Most entries, newest, 1 to 120 (default 40). |
offset |
integer |
at least 0; default 0 |
Skip this many before the first one returned (default 0), to page through the whole list in the order above. A cut list's truncated.next_offset is the value for the next page. |
Returns
aliases_checkedarray, optional: query and the other names checked with it (the alias table, each side of a slash).total_countintegercounts_by_kindarray, optional: [{<key>, count}]counts_by_yeararray, optional: [{<key>, count}]entriesarray: Newest first. Each entry's date is the Chicago day its issue went out; publish_date is the issue's UTC timestamp as stored.
Plus the envelope every tool carries: applied, truncated when something was cut, and server_version.
Pages entries with limit and offset; a cut page says where the next starts in truncated.next_offset.
What Thingy is told in chat
The chat loop binds the same schema with the description written for Thingy’s app:
What Jamie was watching, listening to, installing, reading, playing, drinking, buying or eating over time, extracted from every issue's Currently section. Use for 'what books did Jamie read in YEAR', 'what games has Jamie played', 'what was Jamie watching'. Returns typed entries with issue numbers and dates plus counts by kind and year. If a kind/year filter returns nothing, that label may not exist for that period - fall back to ONE search_archive pass over prose mentions rather than repeated searching. URLs in results are citation metadata for the app; do not quote or narrate raw URLs/paths in the answer.The declaration, as tools/list sends it

}About the archive
What the archive holds, and answers about Thingy himself.
Archive statistics corpus_stats
read-only closed world: archive only MCP WebMCP Thingy chat guest chat
What the archive holds: counts by source and year, the newest and oldest items, link counts, the Weekly Thing's audio editions (count and total length), and for each recent year its distinctive terms, top domains and a sample source.
Parameters
| Parameter | Type | Constraints | Description |
|---|---|---|---|
source_kind |
string |
one of weekly_thing, blog, podcast, link |
Only this source. link is the links Jamie saved on Linking Things: read only when named, and then alone. |
year_range |
integer[2] |
each 1990 to 2100 | [start_year, end_year]; the same year twice for one year. |
year |
integer |
1990 to 2100 | One year: shorthand for year_range [year, year]. |
limit |
integer |
3 to 40; default 12 |
Years of yearly_signals (newest first), top domains and also_in_issue_counts, 3 to 40 (default 12). |
Returns
scopestring, optionalsource_kindstring | null, optionalyear_rangearray | null, optionalsourcesarray: One entry per source kind: item_count, chunk_count, link_count, domain_count, counts_by_year (oldest first), yearly_signals (newest first), top_domains; for the blog, post_count and page_count (undated pages, in item_count and in no year), issues_referenced_count and also_in_issue_counts (issues that reprinted posts), posts_with_linked_from_issues_count and issues_linking_count (issues that linked posts without reprinting them); for the Weekly Thing, audio_editions {count, total_seconds, first, last}; the reference entry (no source_kind or year asked for) has item_count, chunk_count, counts_by_kind, chunk_counts_by_kind and documents [{id, title, url, updated, document_source, document_date}] and no years, and its pages are the blog's pages too; oldest and newest are sources (by the day the year filter reads). On each source, date is the Chicago day it was published (Jamie publishes in Central time); publish_date is the corpus value as stored: a UTC timestamp for an issue, the Chicago day for a blog post, the day for an episode.
Plus the envelope every tool carries: applied, truncated when something was cut, and server_version.
What Thingy is told in chat
The chat loop binds the same schema with the description written for Thingy’s app:
Return deterministic inventory statistics for the active source scope: item counts (the blog's are posts plus undated pages; post_count and page_count split them), chunk counts (dated passages; undated_chunk_count holds FAQ answers and site pages), link counts, newest/oldest item, generated_at, counts_by_year (oldest first), year_count_summary, yearly_signals for the newest limit years, each with its top five subject/title terms, five distinctive chunk-text terms, three most linked domains (the same link measure as top_domains), section counts and one sample source id, the limit most linked external domains (domain_count says of how many; headline picks and blog links, www merged), link kind/category counts, blog also_in_issues cross-reference counts (the limit issues most carried; issues_referenced_count says of how many), and for the Weekly Thing audio_editions {count, total_seconds, first, last} (issues with a spoken audio edition). Optional source_kind isolates "weekly_thing", "blog", or "podcast"; with neither source_kind nor year_range, sources ends with one reference entry (source_kind reference, always_searched): the reference base every search consults, counted by kind (site_page, faq, thing, page, document), with no years, and its documents listed (id, title, document_source, document_date, updated), then one link entry (searched_by_default false, no counts) naming the links Jamie saved on Linking Things (links.thingelstad.xyz). source_kind link counts those instead, which no other call reads: item_count, oldest and newest, counts_by_year by the Chicago year each was saved, counts_by_link_type, counts_by_note_voice, shared_in_issues_count, and top_hosts (host_count says of how many). Use for corpus inventory, freshness, latest indexed date, per-year content breakdowns, year-by-year theme signals, cross-source coverage, and aggregate-domain questions before searching semantically. Pass year_range for earlier years, or a higher limit for more years, domains and issues; truncated counts every list it cut, and top_references pages through every domain.The declaration, as tools/list sends it

}Resources
Clients that support resources can attach a source as context without a tool round trip. Every read goes through the same tools (so a resource and a tool call never disagree) and costs one quota unit per resources/read. A resource is one fixed page; for more, its result names the tool call to make.
| URI template | Title | Type | Description |
|---|---|---|---|
librarian://wt/{n} | Weekly Thing issue | text/markdown | One Weekly Thing issue as markdown, e.g. librarian://wt/351. |
librarian://blog/{id} | Blog post | text/markdown | One thingelstad.com blog post or micropost by its micro.blog id, e.g. librarian://blog/6034145. |
librarian://page/{id} | Page | text/markdown | One thingelstad.com page (About, Resume, a list, a collection, an Open Loop episode) by its page id, the number in page-<id>, e.g. librarian://page/57851. |
librarian://link/{id} | Saved link | text/markdown | One link Jamie saved on Linking Things (links.thingelstad.xyz) by its id, the 12 characters in link-<id>, e.g. librarian://link/734afb8ff14f: the page it saved, when, its tags, the issues that shared it and its note. |
librarian://topic/{slug} | Topic | application/json | A topic by the slug of its page (librarian://topic/apple) or cluster (librarian://topic/ai-and-agents): its catalogue card and its timeline across the archive. |
librarian://year/{yyyy} | A year of the archive | application/json | What the archive holds for one year: counts by source, the year's distinctive terms and domains. |
librarian://on-this-day/{mm-dd} | On this day | application/json | What Jamie published on one calendar day in every year, this one included, e.g. librarian://on-this-day/09-29. |
resources/list offers the newest Weekly Thing issues, read through latest_content with {"source_kind":"weekly_thing","limit":12}. The catalogue changes weekly, and a stateless server cannot notify, so clients re-list on connect.
Prompts
Prompts publish the good call sequences. The routing knowledge Thingy carries in his system prompt reaches MCP clients here: a client that offers prompts shows them as ready-made asks, and each expands into the tool sequence that answers it well. They instruct the calling model, and never speak as Jamie.
How Jamie's thinking changed thinking_over_time
Trace how Jamie's own view of a topic changed across the archive, in Jamie's words, with dated citations.
topicrequired: The topic, person or product to trace, e.g. "RSS" or "Mastodon".
The call sequence it expands to
Trace how Jamie Thingelstad's thinking on "{topic}" changed over time, using the Librarian tools.
1. Call archive_lens with topic "{topic}", voice "jamie" and operation "by_year": when Jamie wrote about it in Jamie's own words, and how much each year.
2. Pick three to five turning points: the first mention, the busiest years, any year the position shifts, and the latest mention. Read each with get_source (pass its id; pass section to read one part whole).
3. Call compare_eras for "{topic}" with an early span as year_a and a recent span as year_b, voice "jamie", to set the early and the recent view side by side.
4. Write a short, dated account of how the view changed. Quote only Jamie's own words; when a passage is a link Jamie shared rather than Jamie's opinion, say so.
Cite every source as a markdown link to its url: [WT351](url) for a Weekly Thing issue, the title for a blog post, the episode for a podcast. If the lens finds little, say so plainly rather than stretching thin evidence.A year in review year_in_review
A year of the archive: what Jamie published, the themes, what Jamie was into, and the links that mattered.
yearrequired: Four-digit year, e.g. "2021".
The call sequence it expands to
Write a year in review of {year} from Jamie Thingelstad's archive, using the Librarian tools.
1. corpus_stats with year_range [{year}, {year}]: how much was published where, and the year's distinctive terms and domains.
2. list_content with year_range [{year}, {year}] and source_kind "weekly_thing" for the issues; again with source_kind "blog" for the posts.
3. currently_history for {year}: what Jamie was reading, watching, playing and building.
4. top_references for {year}: the sites Jamie linked to most.
5. media_search with year {year} (no query lists them newest first) for a few photos worth showing; view_photo before describing one.
6. Read two or three of the year's defining issues or posts with get_source.
Then write the review: the themes, the moments, what Jamie was into, and the links that mattered. Cite every source as a markdown link to its url: [WT351](url) for a Weekly Thing issue, the title for a blog post, the episode for a podcast.A reading path reading_path
An ordered reading list through one theme of the archive, with why each piece comes where it does.
themerequired: The theme, e.g. "personal knowledge management".length: How many pieces, 3 to 12 (default 6).
The call sequence it expands to
Build a reading path through "{theme}" in Jamie Thingelstad's archive: 6 pieces, in the order a newcomer should read them.
1. archive_lens with topic "{theme}" and operation "reading_path".
2. If the path is thin, archive_gems with theme "{theme}", or search_archive for "{theme}", adds candidates.
3. Use each candidate's skim (description or abstract) to choose, and open the strongest with get_source.
4. Present the path as a numbered list: the title as a markdown link to its url, the date, and one sentence on why it comes at that point. Mix Weekly Thing issues, blog posts and podcast episodes where the archive has them.This week in past years this_week_in_past_years
What Jamie published this week in past years: the archive's on-this-day, a week wide.
date: MM-DD or YYYY-MM-DD (default today in America/Chicago).
The call sequence it expands to
Show what Jamie Thingelstad published this week in past years, using the Librarian tools. 1.on_this_daywith window_days 3. 2. For each year with something, pick the one or two most interesting items; read one withget_sourcewhen its excerpt is not enough. 3. When an item has a photo,view_photocan show it; embed a chosen photo as [](source_url). 4. Present it newest year first: the year, how many years ago, and each item as a markdown link to its url with a line on what it was.
Research brief research_brief
A brief on a person, product, company or project, from what the archive holds about it.
subjectrequired: The person, product, company or project, e.g. "Obsidian" or "Ben Thompson".
The call sequence it expands to
Write a research brief on "{subject}" from Jamie Thingelstad's archive, using the Librarian tools.
1. archive_lens with topic "{subject}" and operation "first_last": when it first and last appears, and where.
2. archive_lens with topic "{subject}", operation "timeline" and voice "jamie": what Jamie said about it, as opposed to what Jamie linked.
3. find_links with topic "{subject}" (or domain, when the subject has a website): the links Jamie shared about it.
4. quote_search for "{subject}" when a claim hinges on an exact mention.
5. Read the two or three most substantial sources with get_source.
Write the brief: what {subject} is according to the archive (not general knowledge), when and how Jamie came to it, Jamie's view in Jamie's own words, the best links shared, and open questions. Cite every source as a markdown link to its url: [WT351](url) for a Weekly Thing issue, the title for a blog post, the episode for a podcast.What this shows
Thingy is Jamie’s librarian and also a working example of how an agent and an MCP server can share one surface. A few things that hold up:
- Build the tools once. The in-house agent and every outside agent call the same 20 handlers. A fix for one is a fix for all, and an outside agent is never a second-class user of the archive.
- Write for the reader of the schema. The same tool carries one description for Thingy’s app and another for an agent with no app around it. Schemas declare every limit, enum and length the server enforces.
- Make errors teach. Every refusal names what was wrong and the one next step. A retired tool names its replacement.
- Say what was left out. Results that are cut stay valid JSON and say exactly what went and how to get it.
- Stateless is enough. A plain JSON-RPC request and reply on Lambda serves Claude, ChatGPT and Claude Code; versioning carries the change signal that notifications cannot.
- Generate the documentation. This page is rendered at build time from the surface the server exports, and both repositories check it in CI, so it cannot describe a tool that does not exist.
