AI agents hallucinate APIs, bloat context with stale docs, and write code against outdated signatures.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

### 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. [Security →](https://docfork.com/security) · [Pricing →](https://docfork.com/pricing)
## MCP Setup
> [!TIP]
> Run `npx dgrep setup` to install automatically (use `--agent claude-code` to target one). 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>
```json
{
"mcpServers": {
"docfork": {
"url": "https://mcp.docfork.com/mcp",
"headers": {
"DOCFORK_API_KEY": "YOUR_API_KEY"
}
}
}
}
```
**Claude Code**
```bash
claude mcp add --transport http docfork https://mcp.docfork.com/mcp/oauth
```
**OpenCode**
```jsonc
{
"mcp": {
"docfork": {
"type": "remote",
"url": "https://mcp.docfork.com/mcp",
"headers": { "DOCFORK_API_KEY": "YOUR_API_KEY" },
"enabled": true,
},
},
}
```

**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)_
## Agent Rule
Add a rule so your agent calls Docfork MCP automatically. [Full rule and IDE-specific setup →](https://docfork.com/docs/mcp/best-practices)

## 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.
```
<details>
<summary>Full rule (all clients)</summary>
```markdown
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 →](https://docfork.com/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 →](https://docfork.com/docs/libraries#custom-libraries)
