Context7
Up-to-date docs for LLMs and AI code editors
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 No tab-switching, no hallucinated APIs that don't exist, no outdated code generation.
Want skills and commands too? Context7 is also available as a Claude Code plugin.
Install
1Add the server to Claude Code
claude mcp add --transport http context7 https://mcp.context7.com/mcp2Sign in
Run /mcp in Claude Code and complete the login flow for this server.
These instructions target Claude Code. Check the publisher's documentation for support in other Claude surfaces; a valid server URL alone does not establish compatibility.
