Add this server to your MCP client. Auth is handled automatically — no manual setup needed.

Claude Code

Add to .mcp.json in your project root:

{
  "mcpServers": {
    "metricduck": {
      "type": "http",
      "url": "https://mcp.metricduck.com/mcp"
    }
  }
}

Or via CLI: claude mcp add --transport http -s project metricduck https://mcp.metricduck.com/mcp

Using Claude Desktop, Cursor, Windsurf, or a headless agent with an API key? See the full setup guide for client-specific configs.

Note: MCP clients handle authentication and transport automatically. Do not manually call this endpoint with curl or raw HTTP — MCP uses Streamable HTTP, not simple JSON-RPC POST.
