Connects to Context7.com's documentation database to provide up-to-date library and framework documentation with intelligent project ranking and customizable token limits.
Context7-MCP is a server implementation that provides AI assistants with access to up-to-date documentation and code examples for various libraries and frameworks. Developed by Upstash, this TypeScript-based server connects to Context7.com's documentation database, offering two main tools: one for resolving library names into compatible IDs, and another for retrieving relevant documentation with customizable token limits and topic filtering. The implementation includes intelligent project ranking algorithms to help find the most relevant documentation based on user queries, making it particularly valuable for developers seeking current technical information beyond an AI's knowledge cutoff date.
