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. Authenticate with Context7 when prompted.
Context7 is an MCP server that delivers up-to-date, version-specific documentation and code examples directly into your prompts. It solves a common problem with LLMs: outdated training data leading to hallucinated APIs and deprecated code patterns. Instead of relying on stale information, Context7 pulls current documentation straight from source repositories.
The plugin provides two main tools: resolve-library-id for matching library names to Context7-compatible identifiers, and query-docs for retrieving documentation for specific libraries. You can even target specific versions by mentioning them in your prompt.
How to use: Simply add "use context7" to any prompt where you need current documentation. For example: "Create a Next.js middleware that checks for a valid JWT in cookies. use context7" or "Configure a Cloudflare Worker script to cache JSON API responses. use context7". You can also specify exact libraries with "use library /supabase/supabase for API and docs".
