context7

What your AI can do with it

• Pull up-to-date code documentation for a library or API
• Fetch docs while the agent writes code
• Provide version-specific reference material for a prompt
• Supply documentation for functions and options the agent needs

Getting started

1. Have an AI agent that supports MCP servers.
2. Add the Context7 MCP server to that agent's configuration.
3. Configure the server with any required connection details.
4. Restart or reload the agent so it picks up the new server.
5. Ask the agent to write code that uses a library and let it request docs.

Install context7

The server’s own address, for the clients that take one directly. Or connect Ahel once and every client you use reads it from one address, with the account kept on Ahel rather than in each client’s config.

• Claude Code

  claude mcp add --transport http --scope user context7 'https://mcp.context7.com/mcp'Copy

  Run it once in your project, then open /mcp to approve any sign-in the server asks for.

• Claude Desktop

  https://mcp.context7.com/mcpCopy

  Add a custom connector in Settings, paste this address, and approve the sign-in.

• Cursor

  cursor://anysphere.cursor-deeplink/mcp/install?name=context7&config=eyJ1cmwiOiJodHRwczovL21jcC5jb250ZXh0Ny5jb20vbWNwIn0=Copy

  Open the link and Cursor adds the server at that address.

• ChatGPT

  https://mcp.context7.com/mcpCopy

  In Settings, enable Developer mode, create an MCP app, and paste this address. Your plan and workspace must allow custom apps.

• Codex

  codex mcp add context7 --url 'https://mcp.context7.com/mcp'Copy

  Run it once, then sign in with codex mcp login context7 if the server asks for an account.
