❌ Without Context7

LLMs rely on outdated or generic information about the libraries you use. 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• ❌ Code examples are outdated and based on year-old training data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 MCP pulls up-to-date, version-specific documentation and code examples straight from the source — and places them directly into your prompt.

Add use context7 to your prompt (or [set up a rule](#add-a-rule) to auto-invoke):

Create a Next.js middleware that checks for a valid JWT in cookies
and redirects unauthenticated users to `/login`. use context7

Configure a Cloudflare Worker script to cache
JSON API responses for five minutes. use context7

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 No tab-switching, no hallucinated APIs that don't exist, no outdated code generation.

Installation

> [!NOTE] > API Key Recommended: Get a free API key at context7.com/dashboard for higher rate limits.

Install in Cursor

Go to: Settings -> Cursor Settings -> MCP -> Add new global MCP server

Pasting the following configuration into your Cursor ~/.cursor/mcp.json file is the recommended approach. You may also install in a specific project by creating .cursor/mcp.json in your project folder. See Cursor MCP docs for more info.

> Since Cursor 1.0, you can click the install button below for instant one-click installation.

Install in Claude Code

Run this command. See Claude Code MCP docs for more info.

Claude Code Local Server Connection

claude mcp add --scope user context7 -- npx -y @upstash/context7-mcp --api-key YOUR_API_KEY

Claude Code Remote Server Connection

claude mcp add --scope user --header "CONTEXT7_API_KEY: YOUR_API_KEY" --transport http context7 https://mcp.context7.com/mcp

> Remove --scope user to install for the current project only.

Install in Opencode

Add this to your Opencode configuration file. See Opencode MCP docs for more info.

  }
}

Install with ctx7 setup

Set up Context7 MCP for your coding agents:

npx ctx7 setup

Authenticates via OAuth, generates an API key, and configures the MCP server and rule for your agents. Use --cursor, --claude, or --opencode to target a specific agent.

Other IDEs and Clients →

OAuth Authentication

Context7 MCP server supports OAuth 2.0 authentication for MCP clients that implement the MCP OAuth specification.

To use OAuth, change the endpoint from /mcp to /mcp/oauth in your client configuration:

- "url": "https://mcp.context7.com/mcp"
+ "url": "https://mcp.context7.com/mcp/oauth"

OAuth is only available for remote HTTP connections. For local MCP connections using stdio transport, use API key authentication instead.

Important Tips

Add a Rule

To avoid typing use context7 in every prompt, add a rule to your MCP client to automatically invoke Context7 for code-related questions:

• Cursor: Cursor Settings > Rules
• Claude Code: CLAUDE.md
• Or the equivalent in your MCP client

Example rule:

Always use Context7 MCP when I need library/API documentation, code generation, setup or configuration steps without me having to explicitly ask.

Use Library Id

If you already know exactly which library you want to use, add its Context7 ID to your prompt. That way, Context7 MCP server can skip the library-matching step and directly continue with retrieving docs.

Implement basic authentication with Supabase. use library /supabase/supabase for API and docs.

The slash syntax tells the MCP tool 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:

How do I set up Next.js 14 middleware? use context7

Context7 will automatically match the appropriate version.

Available Tools

Context7 MCP provides the following tools that LLMs can use:

• 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
