Overview

Description from the maker (original English)

Inspect editable image source clues. No C2PA signature verification or authenticated origin.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Design, images & audio

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • The registry lists no key to fill in.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "ai-image-detector": {
      "command": "npx",
      "args": [
        "-y",
        "checkaifree-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add ai-image-detector -- npx -y checkaifree-mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "ai-image-detector": {
      "command": "npx",
      "args": [
        "-y",
        "checkaifree-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "ai-image-detector": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "checkaifree-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Check AI Free — Image Source Clues safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.2) reached the registry 21 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Check AI Free MCP server

Official MCP adapter for Check AI Free. It uploads a selected image for source/header inspection and returns editable metadata observations with limitations. It does not verify C2PA signatures, authenticate an origin or identify an exact generator.

Install

{

"mcpServers": { "checkaifree": { "command": "npx", "args": ["-y", "checkaifree-mcp"] } } }

Use this stdio configuration in an MCP client that supports local commands. No service API key or account is required; rate limits and availability apply.

Tools

  • detect_ai_image: accepts one of image_url, file_path, or image_base64. Read source observations; metadata-only readings do not display a model percentage.
  • inspect_c2pa_provenance: accepts image_url or file_path. The historical tool name is retained for compatibility. It observes source markers and camera fields; signatures, asset binding and certificate trust are not verified.

Supported inputs: JPEG, PNG and WebP up to 10 MiB. A supplied URL is fetched by this Node process; the selected image bytes and filename are then sent to the Check AI Free backend. Local files and base64 input are also uploaded. This adapter is not an in-browser/local-only checker. Do not supply sensitive images without reviewing image handling.

The current adapter calls the source/header endpoint. It does not run the website's separate image re-encoding/pixel-model fallback. Missing metadata can therefore remain inconclusive. Use the website for the full user-facing flow. Source text is editable; no metadata observation or model estimate is proof of authenticity or account identity.

Reading example

An illustrative source-only response might say:

Source text suggests AI generation. No completed model score; source clues alone do not establish a probability. Source fields are editable. C2PA signatures are not verified.

This is an explanation of output semantics, not an accuracy benchmark. The method page documents the product's capabilities and limits.

Development and release checks

npm ci

npm test npm pack --dry-run

The default tests are offline: output semantics, protocol initialization/tool discovery and missing-input rejection. test:live retains the legacy integration runner and requires explicit review of its fixtures and network requests before use. Release checks do not need paid provider calls.
