Pull up-to-date, version-specific library docs and code examples into Claude.

What it does

Context7 by Upstash pulls live documentation into Claude's context on demand.

What it gives Claude:

Up-to-date docs for thousands of libraries and frameworks
Version-specific API signatures and code examples
Fewer hallucinated or outdated API calls when generating code

Works with no API key at standard rate limits. A free key from context7.com/dashboard raises the limits — append --api-key YOUR_API_KEY to the install command. A hosted remote endpoint also exists at https://mcp.context7.com/mcp.

Runs the project's installer (clone + dependencies + config). Follow any prompts. After this finishes, the server is ready to register with Claude Code in the next step.
Restart Claude Code.
Quit and reopen Claude Code so it picks up the new MCP registration. Run /mcp inside Claude Code to confirm the server is connected.
Use it.
Ask Claude naturally. It will call the server's tools when your request matches one. Tool calls show up inline so you can see exactly what Claude is doing.
