Context7 MCP Setup

Context7 is an MCP server that gives the AI up-to-date, version-specific documentation for many libraries (Next.js, Prisma, Supabase, React, etc.). It’s already configured in this project (.vscode/mcp.json and .cursor/mcp.json). Use “use context7” in prompts when you want current docs for a library.

Rate limits and API key

The project config uses Context7 without an API key. That works but has lower rate limits. If you hit limits or want more usage:

1. Get a free API key: Sign in at context7.com, go to the dashboard, and create an API key.
2. Enable it in your user config (do not put the key in the repo):
   • VS Code: Command Palette → MCP: Open User Configuration. Add or edit the context7 server and set a header, e.g. "CONTEXT7_API_KEY": "your-key" in the headers object.
   • Cursor: Edit ~/.cursor/mcp.json and add the header to the context7 entry, e.g. "headers": { "CONTEXT7_API_KEY": "your-key" }.

After adding the key, reload the editor so the updated config is used. See Context7 API keys and Plans & pricing for limits and options.
