WHAT IT DOES

What list_domains does on TrekMail MCP Server

AI agents call list_domains to retrieve information from TrekMail MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_domains is rated Low

This tool retrieves and queries domain information from the TrekMail account without performing any side effects, modifications, or state changes. It is a straightforward read operation that falls squarely into the Read category with low severity, as unauthorized access to domain listings poses minimal risk compared to write, execute, or destructive operations.

From the tool's definition Tool description explicitly states 'List domains' and 'Returns paginated results', indicating a data retrieval operation with filtering and search capabilities but no modification or execution of actions.

RECOMMENDED RULE

The rule that runs list_domains safely

list_domains Allowed

list_domains is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect TrekMail MCP Server, apply this rule, and every list_domains call is checked against it from then on.
