Context7
An MCP server that fetches current, version-specific documentation and code examples for thousands of libraries — ending hallucinated APIs from stale training data.
How to Install MCPs
- Visit the MCP repository using the link below
- Follow the installation instructions (usually npm install or similar)
- Add the MCP configuration to your claude_desktop_config.json
- Restart Claude Desktop to load the MCP server
Context7 solves one of the most common failure modes in AI coding: the model confidently using an API that changed two versions ago. Add "use context7" to a prompt (or let Claude call it automatically) and it pulls current, version-specific documentation and real code examples straight into context.
It covers thousands of popular libraries and frameworks and is one of the most-installed MCP servers in the ecosystem.
**Install (Claude Code):** `claude mcp add context7 npx @upstash/context7-mcp`Categories:
