Context7 Platform -- Up-to-date docs for AI agents
What it is
LLMs rely on outdated or generic information about the libraries you use. You get: ❌ Code examples are outdated and based on year-old training data ❌ Hallucinated APIs that don't even exist ❌ Generic answers for old package versions Context7 pulls up-to-date, version-specific documentation and code examples straight from the source — and gives them to your coding agent.
When to use it
Reach for context7 when you want Claude, Cursor or any MCP client to reach a new tool, API or data source — it's written in TypeScript and fits stacks tagged llm, mcp, vibe-coding, ai-agents.
