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

Your choice stays on this device in a cookie; no account needed.

Values you fill in

CHRONOVERIFY_API_KEY secret env
Your ChronoVerify API key (cv_live_...). Optional: omit to use the free, rate-limited public path.

Common questions

Is Chronoverify 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?

You need to fill in: CHRONOVERIFY_API_KEY

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 (0.1.9) reached the registry 3 months 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?

chronoverify-mcp

An MCP server for ChronoVerify. It gives any MCP-compatible AI agent (Claude Desktop, Cursor, Cline, VS Code, and others) the tools 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 or AI-generation detector. Results are investigative triage to support human review, not proof.

ChronoVerify is a C2PA Conformant Validator, listed on the C2PA Conforming Products List (record 019f8a20-6452-7a43-b11b-59d0b0e4a84a; validation of JPEG, PNG, WebP, and AVIF). Details: https://chronoverify.com/compliance#conformance

Source and issues: github.com/beeswaxpat/chronoverify-mcp

Listed on Smithery: https://smithery.ai/servers/beeswaxpat/chronoverify-mcp

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

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 (verification only; signed reports always need a key).

Tools

`verify_image`

Verify a photo's capture time and provenance. 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.

Optionally set permalink: true to also store the verdict (never the image) and get back an unlisted, shareable link to it in the permalink field, for citing the result to people or in reports. Keyless links expire after 90 days; links minted with an API key do not expire.

It returns a human-readable summary and a typed structured object so an agent can branch on the result without parsing prose:

"schema_version": "v1", "verdict": "consistent", "confidence": 58, "headline": "Metadata is internally consistent. No manipulation signals fired.", "summary": "...", "capture_time": { "value": "2026-03-14T09:21:30", "source": "exif", "consistent": null }, "capture_device": { "make": "Canon", "model": "EOS R6", "software": "Firmware 1.8.1" }, "capture_location": { "present": false, "place": null }, "c2pa": { "present": false, "validated": null, "validation_state": null, "signature_valid": null, "trust_list_match": null, "signer": null }, "integrity": { "sha256": "1313339a...", "sha512": "93a81e4a...", "format": "JPEG", "width": 1200, "height": 800, "c2pa_validator_enabled": true }, "permalink": null, "limits": "ChronoVerify returns investigative triage, not proof.", "source": "ChronoVerify (https://chronoverify.com)" }

The verdict enum:

provenance_confirmed: a trusted C2PA Content Credential validated against the official trust list.
consistent: metadata holds up and no manipulation signal fired (consistent with an unedited capture, not proof).
inconclusive: not enough signal to decide.
metadata_anomaly: the metadata contradicts itself.
manipulation_indicated: pixel forensics flagged possible editing for human review.

`get_signed_report`

Generate a signed PDF audit report for one image: the chain-of-custody / compliance record (for example an EU AI Act Article 50 transparency record, an insurance or legal evidence file, or a newsroom audit trail). Takes one of file_path or image_base64 (this endpoint does not fetch URLs) and an optional out_path. Writes the PDF and returns the path. Requires CHRONOVERIFY_API_KEY; metered as a premium report unit. The report carries an Ed25519 signature you can verify against the public key at https://chronoverify.com/v1/key.

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"
"Validate the C2PA Content Credentials on this image and tell me the signer."
"Verify this photo and give me a shareable link to the verdict."
"Generate a signed provenance report for ./evidence/claim-001.jpg and save it to ./reports/"
