## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__agentpay-lookup__lookup_domain_report` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__agentpay-lookup__lookup_dns` `mcp__agentpay-lookup__lookup_domain_report` `mcp__agentpay-lookup__lookup_ip` `mcp__agentpay-lookup__lookup_whois` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `agentpay-lookup`:

```json
{
  "permissions": {
    "allow": [
      "mcp__agentpay-lookup__lookup_dns",
      "mcp__agentpay-lookup__lookup_whois",
      "mcp__agentpay-lookup__lookup_ip",
      "mcp__agentpay-lookup__lookup_domain_report"
    ],
    "ask": [],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__agentpay-lookup__lookup_dns`: untrusted-input
- `mcp__agentpay-lookup__lookup_whois`: untrusted-input
- `mcp__agentpay-lookup__lookup_ip`: untrusted-input
- `mcp__agentpay-lookup__lookup_domain_report`: private-data, untrusted-input
