CAA Record Grounding Data for AI Agents

The tool

The API parses CAA record strings and provides detailed information about issuance policies, including recognized CA providers and critical flags.

Once your client is connected to the VerveContext MCP server, this appears in its tool list as CAARecordGroundingDataforAIAgents. It is read-only and open-world: it fetches, it never mutates anything on your side, so most clients will call it without asking you to confirm.

{
  "name": "CAARecordGroundingDataforAIAgents",
  "arguments": {
    "record": "example.com. 3600 IN CAA 0 issue \"letsencrypt.org\""
  }
}

What that looks like in a conversation

You don't name the tool — the model picks it. Asking about example.com. 3600 IN CAA 0 issue "letsencrypt.org" in the terms this source covers is enough for it to reach for CAARecordGroundingDataforAIAgents on its own.

Connecting

One server URL covers every source in the catalog, including this one. Authorization is OAuth — the client opens a browser once and there is no key to paste into a config file.

{
  "mcpServers": {
    "vervecontext": {
      "url": "https://api.vervecontext.com/v1/mcp"
    }
  }
}

Per-client setup — Claude Desktop, Cursor, VS Code, ChatGPT — is on the MCP setup page.

Arguments

These are the properties on the tool's inputSchema, so a well-behaved client validates them before the call is made.

What the model gets back

The result carries a structuredContent object matching the tool's declared outputSchema, so a client can read fields without parsing prose. status is "ok" on success and error is null; a null field means the value wasn't available for that input, not that the call failed.

{
  "status": "ok",
  "error": null,
  "data": {
    "raw_record": "example.com. 3600 IN CAA 0 issue \"letsencrypt.org\"",
    "parsed": {
      "domain": "example.com",
      "ttl": 3600,
      "class": "IN",
      "flags": 0,
      "tag": "issue",
      "value": "letsencrypt.org"
    },
    "ca_info": {
      "name": "Let's Encrypt",
      "type": "Free",
      "wildcard_support": true
    },
    "interpretation": {
      "meaning": "Only letsencrypt.org is authorized to issue certificates",
      "restriction": "Restricted to specific CA",
      "critical": false,
      "critical_explanation": "Non-critical - CA may proceed if not understood"
    },
    "tag_description": "Authorizes a CA to issue certificates (any type)",
    "is_valid": true
  }
}

Fields

Why ground on it

A model can produce something that looks like this answer from its training data, and be confidently out of date or simply wrong. This source returns the current value with a shape you can check, which is the difference between an answer you can cite and one you have to hedge.

Point an evaluation at raw_record: it is the field most worth pinning a claim to, and it is either present and current or absent — never plausibly invented.

Failure modes

Errors come back as tool errors with a sentence the model can act on, not a bare status code.
