Context7

Up-to-date documentation for any library, on demand.

Context7 feeds an assistant current, version-specific documentation for thousands of libraries and frameworks — instead of letting it guess from training data. For anyone who codes with an AI assistant, this removes the single most common failure mode: confidently outdated API usage. No API key required for normal use.

Install Context7

You need: an AI app that supports skills (pick yours above) · Node.js (LTS) — one-time install from nodejs.org. Check with `node -v` in a terminal.

Open Settings → Developer → Edit Config in Claude Desktop (this opens claude_desktop_config.json) and merge this block, then fully restart the app:

{
  "mcpServers": {
    "context7": {
      "command": "npx",
      "args": [
        "-y",
        "@upstash/context7-mcp"
      ]
    }
