ChronoVerify agent recipes

Drop-in recipes to give any AI agent one capability: verify a photo's capture time and provenance (cryptographic C2PA Content Credentials validation, EXIF and XMP metadata, and classical pixel forensics) and return one verdict with a confidence and a signed audit record.

Provenance-first, not a deepfake or AI-generation detector. Results are investigative triage, not proof.

One-click MCP install

Or paste this into your MCP client config (Claude Desktop, Claude Code, Cline, Windsurf):

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

Omit the env block to use the free, rate-limited public path. See mcp/install.md for every client.

Direct function calling

Copy-paste tool definitions:

• tool-definitions/openai-chat-completions.json
• tool-definitions/openai-responses.json
• tool-definitions/anthropic-messages.json

When the model calls chronoverify_verify_image, POST the arguments to https://chronoverify.com/v1/verify and return the JSON verdict.

Frameworks

Point each framework's MCP adapter at the published server:

• frameworks/langchain.py
• frameworks/llamaindex.py
• frameworks/crewai.py
• frameworks/n8n.md

SDKs

Runnable examples on the first-party SDKs:

• Python (examples/example.py): pip install chronoverify
