chronoverify-mcp

An MCP server for ChronoVerify. It gives any MCP-compatible AI agent (Claude Desktop, Cursor, Cline, and others) one tool, verify_image, to check a photo's capture time and provenance: C2PA Content Credentials, EXIF and XMP metadata, and classical pixel forensics, fused into one verdict (provenance_confirmed, consistent, inconclusive, metadata_anomaly, or manipulation_indicated) with a 0 to 100 confidence.

Provenance-first, not a deepfake detector. Results are investigative triage to support human review, not proof.

Get an API key (the first 100 verifications each month are included): https://chronoverify.com/pricing . Without a key, the server uses the free, rate-limited public path.

Install

Add it to your MCP client config. For Claude Desktop (claude_desktop_config.json) or any MCP client:

{
  "mcpServers": {
    "chronoverify": {
      "command": "npx",
      "args": ["-y", "chronoverify-mcp"],
      "env": { "CHRONOVERIFY_API_KEY": "cv_live_..." }
    }
  }
}

Omit the env block to use the free public path.

The tool

verify_image takes exactly one of:

• url: a publicly reachable image URL (the server fetches it),

• file_path: an absolute path to a local image, or

• image_base64: base64-encoded image bytes.

It returns the verdict, the confidence, the capture time and device when present, the C2PA status, and the SHA-256 of the file.

Example prompts

• "Verify the provenance of /Users/me/Downloads/photo.jpg"

• "When was the photo at this URL taken, and has it been edited? https://example.com/photo.jpg"
