Proofly MCP Integration

This document describes two ways to integrate Proofly's deepfake detection capabilities with Model Context Protocol (MCP) compatible clients:

1. Via a Hosted MCP Server (https://mcp.proofly.ai): For clients that connect to MCP servers using a URL (e.g., Cursor, Cascade/Windsurf).
2. Via a Local CLI MCP Server (proofly-mcp npm package): For clients that can execute a local command for an MCP server (e.g., Claude Desktop).

Both integration methods ultimately use the Proofly API (https://api.proofly.ai) for analysis.

1. Using the Hosted MCP Server (https://mcp.proofly.ai)

This is the recommended method for MCP clients that connect to servers via HTTP/SSE URLs, such as Cursor, Cascade/Windsurf, etc.

Configuration Examples (for URL-based clients)

Add one of the following configurations to your MCP client (e.g., in mcp_config.json):

A. Streaming (SSE - Recommended where supported):

{
  "proofly": {
    "serverUrl": "https://mcp.proofly.ai/sse",
    "supportedMethods": [
      "analyze-image",
      "analyze",
      "get-face-details",
      "check-session-status"
    ],
    "auth": { "type": "none" } // Or your specific auth if Proofly API https:/get.proofly.ai requires it
  }
}

B. Standard HTTP (Non-streaming):

{
  "proofly": {
    "serverUrl": "https://mcp.proofly.ai/mcp",
    "supportedMethods": [
      "analyze-image",
      "analyze",
      "get-face-details",
      "check-session-status"
    ],
    "auth": { "type": "none" } // Or your specific auth if Proofly API https:/get.proofly.ai requires it
  }
}

Note: The mcp.proofly.ai server is a separate deployment. This proofly-mcp npm package is not used to run or configure mcp.proofly.ai.

2. Using the Local CLI MCP Server (proofly-mcp npm package)

This proofly-mcp npm package provides a command-line tool that acts as an MCP server. It's designed for MCP clients that can execute a local command and communicate with it via stdio (e.g., Claude Desktop).

Features of proofly-mcp CLI

• Acts as a local MCP server communicating via stdio.
• Analyzes images for deepfake detection (from Base64 or URL).
• Checks session status for an analysis.
• Gets detailed information about specific detected faces.

Installation of proofly-mcp CLI

Global Installation (Recommended for direct use by clients like Claude Desktop):

npm install -g proofly-mcp

Local Installation (For programmatic use or if preferred):

npm install proofly-mcp

Environment Variables for proofly-mcp CLI (Optional)

• PROOFLY_API_KEY: Your Proofly API key. The proofly-mcp CLI will use this API key if the variable is set when communicating with Proofly API https://get.proofly.ai.

Configuration Examples (for command-based clients using proofly-mcp)

Claude Desktop:

Add to your Claude Desktop config file (e.g., claude_desktop_config.json). The recommended way is to use npx to ensure you are running the latest version without requiring a global install:

{
  "mcpServers": {
    "proofly": {
      "command": "npx",
      "args": [
        "-y", // The -y flag might be specific to your npm/npx version or aliasing for auto-confirmation.
              // Alternatively, for most npx versions: "proofly-mcp@latest"
        "proofly-mcp@latest"
      ],
      "supportedMethods": [
        "analyze-image",
        "analyze",
        "get-face-details",
        "check-session-status"
      ]
    }
  }
}

Alternatively, if you have proofly-mcp installed globally (npm install -g proofly-mcp), you can use:

{
  "mcpServers": {
    "proofly": {
      "command": "proofly-mcp",
      "args": [],
      "supportedMethods": [
        "analyze-image",
        "analyze",
        "get-face-details",
        "check-session-status"
      ]
    }
  }
}

• Claude Desktop will execute the specified command, which then acts as the MCP server.

Other command-capable MCP Clients:

If your MCP client can launch a local command, configure it to run proofly-mcp. Conceptual example (actual config varies by client):

{
  "mcpServers": {
    "proofly": {
      "type": "command",
      "command": "proofly-mcp",
      "supportedMethods": [
        "analyze-image",
        "analyze",
        "get-face-details",
        "check-session-status"
      ]
    }
  }
}

Available MCP Methods

The following methods are supported by both the https://mcp.proofly.ai hosted server and the proofly-mcp CLI server.

analyze-image

Analyzes an image provided as a base64 string for deepfake detection.

Parameters:

• imageBase64: string - Base64 encoded image data.
• filename: string - Original filename with extension (e.g., 'image.jpg').
• format: "text" | "json" (optional, default: "text") - Output format.

analyze

Analyzes an image from a URL for deepfake detection.

Parameters:

• imageUrl: string - URL of the image to analyze.
• format: "text" | "json" (optional, default: "text") - Output format.

check-session-status

Checks the status of a deepfake analysis session.

Parameters:

• sessionUuid: string - Session UUID to check status for.
• format: "text" | "json" (optional, default: "text") - Output format.

get-face-details

Gets detailed information about a specific face detected in an image analysis session.

Parameters:

• sessionUuid: string - Session UUID from a previous analysis.
• faceIndex: number - Index of the face to get details for (starting from 0).
