connect

connect

Find the shortest chain of in-text links from one Edgepedia article to another (at most 6 hops), with the sentence that makes each hop; pass two ids as `search` returns them.

fetch

fetch

Read an encyclopedia article in full: one Edgepedia article as Markdown with its citations, by a `search` result's id. Returns id, title, text, url, and metadata (topic path, license, credit). A `topic:` id lists that topic's parent, narrower topics, and articles, 120 a page; `topic:root` is the top of the tree, `topic:geo` the geography tree. `citations: false` gives [n] markers instead of inline source links. Show the `credit` line with any text you quote.

related

Find encyclopedia articles related to an Edgepedia article: its topic-mates, a few from each neighboring topic, and its geography neighbors. Pass its id, as for `fetch`. Returns groups of results; `fetch` a group's `topic` id for more.

resolve

resolve

Find which encyclopedia article a name means: Edgepedia's best match for a person, place, thing, or concept named in a text, with a confidence, whether the name is ambiguous, and the alternatives. Pass the name ("Mercury"), and optionally words from the text around it (`context`: "planet orbit") or a topic id the article must sit under (`type`). Returns `result` (id, title, url) and `alternatives`; pass an id to `fetch`.

search

Search an encyclopedia for facts about a person, place, thing, event, or concept: Edgepedia, more than 400,000 articles with citations. Pass the subject's name ("Mount Fuji", "photosynthesis"), not a question; other names and misspellings match, and when no title matches, articles whose text does follow, marked `match: fulltext`. Returns results with id, title, url, and preview text, plus a `topic:` result when the query names a topic ("painters"); pass an id to `fetch`. `limit` and `page` reach further results.

Edgepedia — questions

Answers built from our own checks of this server.

What can Edgepedia do?

It exposes 5 tools, read directly from the server on our last check. Among them: connect, fetch, related, resolve, search. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Edgepedia working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 92 checks got a reply (0.0%), average response time 118 ms. The bar chart above shows every period we have measured.

The registry lists Edgepedia as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Edgepedia?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Edgepedia need an API key?

No. Edgepedia completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

Is Edgepedia open source?

The code is open source: it is published under the MIT licence and 1 stars on GitHub. The licence covers the code in the repository, not the hosted service at edgechat.ai, which runs on its operator's own terms.
