What it does
Upstash's Context7 MCP server connects Claude Code to a hosted remote MCP endpoint that pulls version-specific documentation and code examples directly from source repositories. Works anonymously out of the box; set CONTEXT7_API_KEY for higher rate limits.
Install
Claude Code
/plugin marketplace add anthropics/claude-plugins-official
/plugin install context7@claude-plugins-official

The official marketplace registers itself automatically on Claude Code's first interactive launch, so the marketplace-add step is often a no-op; running it is still safe and works on any machine.
