What is Context7?

Context7 is a free, open-source Model Context Protocol (MCP) server that provides up-to-date documentation and code examples for AI coding assistants. It acts as a bridge between official documentation repositories and LLMs (like GPT-4 or Claude), reducing code hallucinations by supplying fresh, relevant context for programming libraries and framework

Key Aspects and Usage Examples

Real-time Documentation: It indexes and cleans up documentation, offering up-to-date information rather than relying on outdated LLM training data.

MCP Server Integration: Configurable with tools like Cursor, Windsurf, or Claude Code to automatically inject context during coding.

Library Support: Covers nearly 20,000 libraries, allowing users to search and retrieve specific documentation with code examples.

Specific Examples:

Direct Querying: Users can pull documentation directly into their prompt for libraries like Next.js or Supabase.

Version Control: Helps handle version-specific documentation for complex projects.

Workflow: Instead of looking up documentation, developers can use context7 to load documentation directly into their AI editor.
