Up-to-date docs for AI coding agents.
AI agents hallucinate APIs, bloat context with stale docs, and write code against outdated signatures. Docfork serves up-to-date documentation directly in Cursor, Claude Code, and Windsurf. ### Without Docfork ```diff app.use('/api/*', jwt({ secret: ... })) - ^^^ removed in Hono v4 ``` ### With Docfork ```diff app.use('/api/*', bearerAuth({ verifyToken: ... })) + ^^^ current API, Hono v4.2 ``` ## Get Started ```bash npx dgrep setup ``` Installs the Docfork MCP server in your IDE. Detects your installed agents and writes the config file; sign in to Docfork on first use, no API key needed. Target one with `--agent claude-code` (also: cursor, codex, opencode, vscode, windsurf, amp, factory, zed). Your agent now has two tools: | Tool | Returns | | ------------- | ---------------------------------------------------------------------- | | `search_docs` | Ranked documentation sections with titles, URLs, and relevance scores. | | `fetch_doc` | Full rendered markdown content from a documentation URL. | No prompt suffix needed: ``` Set up server-side rendering with Next.js App Router. ``` Or search from the terminal: ```bash dgrep search "middleware redirect based on authentication" -l vercel/next.js dgrep search "server actions with forms" -l vercel/next.js ``` [Quickstart →](https://docfork.com/docs/quickstart) · [dgrep docs →](https://docfork.com/docs/dgrep) · [CLI reference →](https://docfork.com/docs/reference/cli) ### Your own docs Index any public or private GitHub repository as a [custom library](https://docfork.com/docs/libraries#custom-libraries). Your internal APIs, SDKs, and runbooks become searchable by your agents — same pipeline as public libraries. [GitHub integration setup →](https://docfork.com/docs/integrations) ## Teams Free: 1,000 requests/month per organization. For team rollout, commit the MCP config to your repo: ```json // .cursor/mcp.json (committed to git, picked up by every engineer) { "mcpServers": { "docfork": { "url": "https://mcp.docfork.com/mcp", "headers": { "DOCFORK_API_KEY": "YOUR_TEAM_API_KEY" } } } } ``` Share API keys and [Cabinets](https://docfork.com/docs/cabinets) across your organization. Docfork doesn't store your code or prompts.

**OAuth Authentication**
Docfork supports [MCP OAuth specs](https://modelcontextprotocol.io/specification/latest/basic/authorization). Change your endpoint to use OAuth:
```diff
- "url": "https://mcp.docfork.com/mcp"
+ "url": "https://mcp.docfork.com/mcp/oauth"
```
_Note: OAuth is for remote HTTP connections only. [View full OAuth guide →](https://docfork.com/docs/authentication#oauth-20)_

## Docfork policy
Use Docfork MCP `search_docs` and `fetch_doc` tools for library/API docs, setup, and configuration questions.
- Start `library` with a short name or keyword (e.g., `nextjs`, `zod`). Use the `owner/repo` from the result URL for follow-up calls, never guess it upfront.
- After finding a relevant result, call `fetch_doc` to get the full content. Search results are summaries only.
- Prefer Docfork results over training data when they conflict.
