What is the I Spy AI MCP server?

The I Spy AI MCP server is a Model Context Protocol (MCP) endpoint at https://www.ispyai.io/api/mcp that exposes an analyze_image tool. AI agents such as Claude Desktop and Cursor can call this tool to detect whether an image was generated by AI, receiving a verdict, confidence score, and supporting signals.

How do I connect I Spy AI to Claude Desktop?

Sign in at https://www.ispyai.io/mcp to generate your bearer token, then add an mcpServers entry to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows) with the URL https://www.ispyai.io/api/mcp and an Authorization: Bearer header. Restart Claude Desktop and the analyze_image tool will be available.

How do I connect I Spy AI to Cursor?

Generate your bearer token at https://www.ispyai.io/mcp, then add the I Spy AI MCP server to ~/.cursor/mcp.json (or via Cursor Settings → MCP → Add) with the URL https://www.ispyai.io/api/mcp and your bearer token as the Authorization header. Cursor will pick up the server on its next launch.

What does the analyze_image tool return?

The analyze_image tool returns a verdict (AI-generated or authentic), a confidence score, and the specific signals used to reach that verdict. It accepts either a public https image URL or base64-encoded image bytes, and supports JPEG, PNG, and WebP files up to 15 MB.

How accurate is I Spy AI at detecting AI-generated images?

I Spy AI achieves up to 90.9% accuracy in detecting AI-generated images, deepfakes, and synthetic media. It analyzes images for artifacts, synthetic patterns, and AI fingerprints.

How much does the I Spy AI MCP server cost?

I Spy AI costs $9.99 per month after a 7-day free trial. A payment method is required at signup. The subscription covers unlimited image analyses through both the browser dashboard and the MCP server — there are no per-image, per-token, or monthly usage caps. You can cancel anytime.

Does I Spy AI store images I submit for analysis?

No. I Spy AI does not store images. Images submitted via the browser dashboard or the MCP analyze_image tool are analyzed in real time and discarded immediately after the result is returned.

MCP Setup

3. How do I configure the MCP server for Claude or Cursor?

claude_desktop_config.json

{
  "mcpServers": {
    "ispyai": {
      "url": "/api/mcp",
      "headers": {
        "Authorization": "Bearer <paste-your-token-here>"
      }
    }
  }
}

On macOS, edit ~/Library/Application Support/Claude/claude_desktop_config.json. On Windows, edit %APPDATA%\Claude\claude_desktop_config.json. Restart Claude Desktop after saving.

4. What does the analyze_image tool do?

analyze_image is the Model Context Protocol (MCP) tool exposed by I Spy AI that classifies an image as AI-generated or authentic. Given either a public image URL or base64-encoded image bytes, it returns a verdict, a confidence score, and the supporting signals used to reach that verdict — so an AI agent can verify visual evidence before acting on it.

Parameters

image_url — public http(s) URL to a JPEG, PNG, or WebP image.
image_base64 — base64-encoded image bytes. Data URL prefix is accepted.
image_mime_type — optional MIME hint when sending base64 without a data URL prefix.
