check_domain_health

Check the live SSL/TLS certificate (validity + expiry + issuer), DNS records (A/AAAA/MX/NS resolution), and domain-registration (RDAP) expiry of any public hostname. Each leg fails soft and is reported independently.

Parameters1

hostname

string

required

A public hostname, e.g. example.com

Raw schema

{
  "type": "object",
  "properties": {
    "hostname": {
      "type": "string",
      "description": "A public hostname, e.g. example.com"
    }
  },
  "required": [
    "hostname"
  ],
  "additionalProperties": false
}

check_agent_readiness

Score how ready a website is for AI agents and answer engines. Fetches /llms.txt, /robots.txt, and the homepage and returns a letter grade with per-signal findings. No browser rendering or LLM call — deterministic HTTP/parse.

Parameters1

hostname

string

required

A public hostname, e.g. example.com

Raw schema

{
  "type": "object",
  "properties": {
    "hostname": {

    }
  },
  "required": [
    "hostname"
  ],
  "additionalProperties": false
}

check_mcp_health

Health-check a live MCP (Model Context Protocol) server by URL: performs a real JSON-RPC initialize handshake, then tools/list, and returns whether it is up/degraded/down, its protocol version, server name/version, the callable tool/resource/prompt inventory, transport, and handshake latency. Deterministic — no LLM. Use it to verify your own MCP server is alive and spec-compliant.

url
