## Why hires_list_messages is rated Low

This tool queries existing message data (sent, scheduled, delivery history) without creating, modifying, deleting, or executing any actions. It has minimal blast radius—an AI agent misusing this could at worst review outbound communication logs, which poses no direct risk to data integrity, financial commitments, or system operations. Appropriate for an ATS monitoring use case.

From the tool's own definition: "Tool description states 'List messages' and 'Returns outbound messages only (sent and scheduled)', indicating a retrieval operation with no modifications or side effects. Keywords 'monitoring', 'check', and 'history' confirm read-only intent."

## Use case

AI agents call hires_list_messages to retrieve information from 100Hires MCP Server 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)
