io.github.docfork/docfork

AI agents hallucinate APIs, bloat context with stale docs, and write code against outdated signatures.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

  app.use('/api/*', jwt({ secret: ... }))
-                       ^^^ removed in Hono v4

With Docfork

  app.use('/api/*', bearerAuth({ verifyToken: ... }))
+                       ^^^ current API, Hono v4.2

Get Started

npx dgrep setup --cursor

Installs the Docfork MCP server in your IDE. Detects your dependencies, provisions an API key, and writes the config file. Also supports --claude and --opencode.

Your agent now has two tools:

No prompt suffix needed:

Set up server-side rendering with Next.js App Router.

Or search from the terminal:

dgrep search "middleware redirect based on authentication" -l vercel/next.js
dgrep search "server actions with forms" -l vercel/next.js

Your own docs

Index any public or private GitHub repository as a custom library. Your internal APIs, SDKs, and runbooks become searchable by your agents — same pipeline as public libraries. GitHub integration setup →

Teams

Free: 1,000 requests/month per organization. For team rollout, commit the MCP config to your repo:

// .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 across your organization. Docfork doesn't store your code or prompts. Security → · Pricing →

MCP Setup

[!TIP] Run npx dgrep setup --cursor (or --claude, --opencode) to install automatically. Manual config below for other clients.

Cursor — <a href="https://cursor.com/en/install-mcp?name=docfork&config=eyJ1cmwiOiJodHRwczovL21jcC5kb2Nmb3JrLmNvbS9tY3AifQ%3D%3D"><img src="https://cursor.com/deeplink/mcp-install-dark.svg" height="20" alt="Add to Cursor"/></a>

{
  "mcpServers": {
    "docfork": {
      "url": "https://mcp.docfork.com/mcp",
      "headers": {
        "DOCFORK_API_KEY": "YOUR_API_KEY"
      }
    }
  }
}

OAuth Authentication

Docfork supports MCP OAuth specs. Change your endpoint to use OAuth:

- "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 →

Agent Rule

## 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.

When writing or debugging code that involves third-party libraries, frameworks, or APIs, use Docfork MCP `search_docs` and `fetch_doc` tools rather than relying on training data.

**Two defaults to follow every time:**

- 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.

Skip Docfork when:

- Language built-ins, general algorithms, syntax stable across versions
- Code or docs the user has already provided in context

When uncertain, default to using Docfork.

FAQ

How is Docfork different from Context7? Both provide MCP servers and CLIs for searching library documentation. Here are the key differences:

• Stack scoping. dgrep init reads your package.json and scopes all searches to your declared dependencies. Cabinets let you version-pin those libraries across a team.
• Resolve once, search many. dgrep init resolves package names to canonical identifiers once and caches the mapping in .dgrep/config.json. No per-query resolution step.
• Hybrid search. Semantic search and BM25 run in parallel, fused via Reciprocal Rank Fusion. AST-aware chunking preserves function boundaries.

Does Docfork store my code or prompts? Your code and prompts never leave your machine. At search time, only the query and library name are sent to Docfork — queries are not stored. Indexed documentation content lives in an upstream vector store; private library content is end-to-end encrypted and deleted atomically when you remove the library. Security →

What libraries are supported? Docfork maintains a curated catalog of popular frameworks. Add any public or private GitHub repository as a custom library. Add custom libraries →
