## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `domain` | string | yes |  |

Parameters from the server's own tool schema.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "lookup_ssl_cert",
    "arguments": {
      "domain": "<domain>"
    }
  }
}
```

## Why lookup_ssl_cert is rated Low

This is a pure data retrieval operation. TLS certificate information is public metadata served by the domain's server during the TLS handshake. Inspecting it has no side effects, does not trigger code execution, and does not modify any state. It is analogous to a DNS lookup or HTTP HEAD request and is commonly used for legitimate security and compliance monitoring.

From the tool's own definition: "Tool description states it 'Inspect[s] a domain's TLS certificate' for 'security audits and uptime monitoring.' The example call passes only a domain name parameter, and the function retrieves certificate metadata (issuer, expiry, SANs—Subject Alternative…"

## Use case

AI agents call lookup_ssl_cert to retrieve information from GoCreative Agent API without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches GoCreative Agent API:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "lookup_ssl_cert": {}
  }
}
```
