context7

Upstash Context7 MCP server for up-to-date documentation lookup. Connects to Context7's hosted remote MCP server (https://mcp.context7.com/mcp) — no local Node.js or npx required — to pull version-specific documentation and code examples directly from source repositories into your LLM context. Works anonymously out of the box; set CONTEXT7_API_KEY for higher rate limits.
