What is Context7 MCP Server?
Context7 MCP is a docs server for AI coding tools. It pulls current library docs so the model is not stuck on training-cut-off APIs. To install it, run claude mcp add --scope user --transport http context7 https://mcp.context7.com/mcp. Client JSON is on mcpcontext7.com.
Context7 MCP fetches live library docs into the editor. This page is the explainer. The install command and JSON live on mcpcontext7.com. The MCP endpoint is mcp.context7.com.
claude mcp add --scope user --transport http context7 https://mcp.context7.com/mcpWhat it is
You add Context7 to Claude Code, Cursor, Claude Desktop, VS Code, or Windsurf as an MCP server. Once connected, the tools are resolve-library-id and get-library-docs. The remote HTTP command is claude mcp add --scope user --transport http context7 https://mcp.context7.com/mcp
Why people install it
The model is often a few months behind the library you have in package.json. That shows up as deprecated APIs, missing methods, and examples that do not compile. Context7 fetches the current docs and puts them in context before the answer.
How to install it
Claude Code: the command in the box, then restart and run claude mcp list. Other clients: JSON at https://mcp.context7.com/mcp, copied from /cursor, /vscode, /claude, or /windsurf.
