You get: - ❌ Code examples are outdated and based on year-old training data - ❌ Hallucinated APIs that don't even exist - ❌ Generic answers for old package versions ## ✅ With Context7 Context7 pulls up-to-date, version-specific documentation and code examples straight from the source — and places them directly into your prompt. ```txt Create a Next.js middleware that checks for a valid JWT in cookies and redirects unauthenticated users to `/login`. use context7 ``` ```txt Configure a Cloudflare Worker script to cache JSON API responses for five minutes. use context7 ``` ```txt Show me the Supabase auth API for email/password sign-up. ``` Context7 fetches up-to-date code examples and documentation right into your LLM's context. No tab-switching, no hallucinated APIs that don't exist, no outdated code generation. Works in two modes: - **CLI + Skills** — installs a skill that guides your agent to fetch docs using `ctx7` CLI commands (no MCP required) - **MCP** — registers a Context7 MCP server so your agent can call documentation tools natively ## Installation > [!NOTE] > **API Key Recommended**: Get a free API key at [context7.com/dashboard](https://context7.com/dashboard) for higher rate limits. Set up Context7 for your coding agents with a single command. The `ctx7` CLI requires Node.js 18 or newer. ```bash npx ctx7 setup ``` Authenticates via OAuth, generates an API key, and installs the appropriate skill. You can choose between CLI + Skills or MCP mode. Use `--cursor`, `--claude`, or `--opencode` to target a specific agent. To remove the generated setup later, run `npx ctx7 remove`. If you globally installed the CLI with `npm install -g ctx7`, remove that package separately with `npm uninstall -g ctx7`. To configure manually, use the Context7 server URL `https://mcp.context7.com/mcp` with your MCP client and pass your API key via the `CONTEXT7_API_KEY` header. See the link below for client-specific setup instructions. **[Manual Installation / Other Clients →](https://context7.com/docs/resources/all-clients)** ## Important Tips ### Use Library Id If you already know exactly which library you want to use, add its Context7 ID to your prompt. That way, Context7 can skip the library-matching step and directly retrieve docs. ```txt Implement basic authentication with Supabase. use library /supabase/supabase for API and docs. ``` The slash syntax tells Context7 exactly which library to load docs for. ### Specify a Version To get documentation for a specific library version, just mention the version in your prompt: ```txt How do I set up Next.js 14 middleware? use context7 ``` Context7 will automatically match the appropriate version. ### Add a Rule If you installed via `ctx7 setup`, a skill is configured automatically that triggers Context7 for library-related questions. To set up a rule manually instead, add one to your coding agent: - **Cursor**: `Cursor Settings > Rules` - **Claude Code**: `CLAUDE.md` - Or the equivalent in your coding agent **Example rule:** ```txt Always use Context7 when I need library/API documentation, code generation, setup or configuration steps without me having to explicitly ask. ``` ## Available Tools ### CLI Commands - `ctx7 library <name> <query>`: Searches the Context7 index by library name and returns matching libraries with their IDs. - `ctx7 docs <libraryId> <query>`: Retrieves documentation for a library using a Context7-compatible library ID (e.g., `/mongodb/docs`, `/vercel/next.js`). ### MCP Tools - `resolve-library-id`: Resolves a general library name into a Context7-compatible library ID. - `query` (required): The user's question or task (used to rank results by relevance) - `libraryName` (required): The name of the library to search for - `query-docs`: Retrieves documentation for a library using a Context7-compatible library ID. - `libraryId` (required): Exact Context7-compatible library ID (e.g., `/mongodb/docs`, `/vercel/next.js`) - `query` (required): The question or task to get relevant documentation for ## More Documentation - [CLI Reference](https://context7.com/docs/clients/cli) - Full CLI documentation - [MCP Clients](https://context7.com/docs/resources/all-clients) - Manual MCP installation for 30+ clients - [Adding Libraries](https://context7.com/docs/adding-libraries) - Submit your library to Context7 - [Troubleshooting](https://context7.com/docs/resources/troubleshooting) - Common issues and solutions - [API Reference](https://context7.com/docs/api-guide) - REST API documentation - [Developer Guide](https://context7.com/docs/resources/developer) - Run Context7 MCP locally ## Packages - [`@upstash/context7-mcp`](https://www.npmjs.com/package/@upstash/context7-mcp) - MCP server - [`ctx7`](https://www.npmjs.com/package/ctx7) - CLI - [`@upstash/context7-sdk`](https://www.npmjs.com/package/@upstash/context7-sdk) - TypeScript SDK - [`@upstash/context7-tools-ai-sdk`](https://www.npmjs.com/package/@upstash/context7-tools-ai-sdk) - Vercel AI SDK tools - [`@upstash/context7-pi`](https://www.npmjs.com/package/@upstash/context7-pi) - pi.dev extension ## Disclaimer 1- Context7 projects are community-contributed and while we strive to maintain high quality, we cannot guarantee the accuracy, completeness, or security of all library documentation.
