Context7 Platform -- Up-to-date code documentation for LLMs and AI code editors
The Lens
Context7 feeds your AI assistant up-to-date documentation for libraries and frameworks. Instead of your LLM guessing API signatures from stale training data, it pulls current docs on demand. One config entry, no API key.
Maintained by Upstash and covers a wide range of popular libraries. The docs are pre-processed and chunked for LLM consumption, so you get relevant sections rather than entire documentation sites. Setup is about as simple as MCP gets.
Install this. It makes every AI coding session better by grounding responses in real documentation. The catch: coverage depends on what Context7 has indexed. Niche or brand-new libraries may not be available yet.
