Context7

Upstash Context7 pulls current, version-specific library docs into the agent so it stops inventing APIs.

The remote server is https://mcp.context7.com/mcp. OAuth is available at https://mcp.context7.com/mcp/oauth if you would rather not put a key in the client config. A local stdio build is npx -y @upstash/context7-mcp.

Source: upstash/context7. The tools resolve a library id and then fetch docs for a question. Treat the API key like any other credential.

Setup snippet

{
  "mcpServers": {
    "context7": {
      "url": "https://mcp.context7.com/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Client config shape varies. Cursor and Claude Desktop use mcpServers. VS Code often uses servers. The values above are the part that matters.
