Overview
Context7 is a Model Context Protocol (MCP) server developed by Upstash that delivers current, version-specific documentation and working code snippets directly into the context of AI coding assistants like Cursor, GitHub Copilot, Windsurf, Claude, and more. By including the simple phrase "use context7" in prompts, developers ensure that their AI tools generate code grounded in accurate, up-to-date documentation, rather than outdated or hallucinated APIs.
Key Capabilities
- Real-time documentation injection: Fetches up-to-date, version-specific docs and examples from the source into prompts.
- Seamless integration across editors: Easily add Context7 as an MCP server via simple configurations in editors like VS Code, Cursor, Windsurf, Claude Desktop/Code, Copilot, Fern, Gemini CLI, JetBrains AI Assistant, and more.
- LLM prompt enhancement: Using “use context7” ensures code generation is based on accurate, source-level information, reducing hallucinations and increasing output correctness.
- Open and developer-friendly: Free for personal use, with public GitHub repo, documentation guides, blog posts and growing community engagement.
