SpyFu MCP by usefulapi

SpyFu MCP by usefulapi

Use your SpyFu account from Claude, Cursor, or any MCP client. Read domain stats, competitors, organic and paid keywords, rankings, top pages and ad history. Hosted, no local install: connect with your own credentials.

Live endpoint: https://spyfu.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://spyfu.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http spyfu https://spyfu.usefulapi.io/mcp, then run /mcp to log in.
• VS Code: Add to VS Code.
• Cursor and other clients: add the URL as a remote MCP server:

{
  "mcpServers": {
    "spyfu": {
      "url": "https://spyfu.usefulapi.io/mcp"
    }
  }
}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your SpyFu credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/spyfu/

On first connect you provide a SpyFu API ID and a SpyFu Secret Key (SpyFu → Account Settings → API Usage). The server validates it and stores it per user. No keys go in config files.
