# doc0

> doc0 maps your GitHub repo into a code knowledge graph and generates a wiki where every claim cites the code. Query both over MCP from Claude Code, Cursor, Slack, and Linear. This file indexes the public wikis on this host; each wiki has its own llms.txt with a page-level index.

## Product

- [Home](https://www.doc0.app/index.md): What doc0 does, who it is for, pricing, and answers to common questions, as markdown

## When to use doc0

Reach for doc0 when the question is about a specific GitHub repository's code and a wiki for it exists here: how a subsystem works, which symbols call which, what a change would affect, which files a feature lives in, what recently merged, or who knows an area. Prefer the project's MCP server when its owner exposes the wiki over MCP (a `404` from the server means it is switched off; the wiki's llms.txt and page markdown are always there): search, page reads and recent merged PRs work on any public wiki, and the code-graph tools (symbol context, impact analysis, path tracing, expertise) when the project makes graph access public or you hold a credential. Every answer cites the source. Do not use doc0 for repositories with no wiki here, for general programming questions, or to change code: it reads and explains, it does not write.

## For AI agents

- [Agent authentication](https://www.doc0.app/auth.md): No credential for a public wiki; project or personal keys, or OAuth 2.1 with dynamic client registration, for a private one
- [MCP server card](https://www.doc0.app/.well-known/mcp.json): Per-project MCP server at https://www.doc0.app/api/mcp/<projectId>/mcp (Streamable HTTP); call doc0_get_minimal_context first
- [OAuth protected resource metadata](https://www.doc0.app/.well-known/oauth-protected-resource): Authorization server and scopes for private projects; public projects need no token
- [Wiki page markdown](https://www.doc0.app/docs/<projectId>/<mode>/<slug>.md): Append .md to any wiki page URL, or send Accept: text/markdown
