Context7

Context7 is an MCP server that addresses inaccuracies in AI-generated code. While LLMs rely on outdated training data, Context7 ensures they generate accurate, up-to-date and version-specific code for the libraries and frameworks used in a project. It does this by pulling the latest documentation and functional code examples directly from framework source repositories and injecting them into the LLM's context window at the moment of prompting. In our experience, Context7 has greatly reduced code hallucinations and reliance on stale training data. You can configure it with AI code editors such as Claude Code, Cursor or VS Code to generate, refactor or debug framework-dependent code.
