MCP server

Connect Claude, Cursor or any MCP client to Rankfield's remote MCP server over Streamable HTTP, with your API key as a bearer token.

The server is a thin layer over the HTTP API: each tool calls the same endpoint with your key and returns its JSON.

#Connect

• URL: https://rankfield.dev/mcp
• Transport: Streamable HTTP (JSON-RPC over POST), protocol versions 2025-11-25, 2025-06-18 and 2025-03-26.
• Auth: the header Authorization: Bearer <key>. Every call needs it, tools/list included.

For a client configured with JSON:

{
  "mcpServers": {
    "rankfield": {
      "type": "http",
      "url": "https://rankfield.dev/mcp",
      "headers": { "Authorization": "Bearer YOUR_API_KEY" }
    }
  }
}

With Claude Code:

claude mcp add --transport http rankfield https://rankfield.dev/mcp --header "Authorization: Bearer YOUR_API_KEY"

Opening the URL in a browser shows connection instructions; tools only answer authenticated POST requests.

#Tools

Each tool takes the same inputs as its endpoint (domain, url or urls, query or queries, cursor, limit, maxAge…), and tools/list gives the exact schemas. The Scrape, Bot View, Brand and Site Map job tools take items: each item is one call's arguments without timeout.

#Example prompts

• "What is the Site Strength of example.com, and which of its referring domains are above 60?"
• "List the external links on https://example.com/pricing and flag the nofollow ones."
• "Export every domain linking to example.com as CSV."
• "What does Bing suggest for running shoes in the en-GB market?"
• "Scrape https://example.com/pricing and list the plans and prices."

Limits are those of the endpoints behind each tool: see Rate limits.
