## Why mautic_list_contact_fields is rated Low

This tool queries and retrieves metadata about contact fields in the Mautic system. It performs a read-only operation with no side effects, no data modification, no code execution, and no destructive capabilities. The blast radius of misuse is minimal—an agent could only discover what fields exist, not access contact data itself or modify system state.

From the tool's own definition: "Tool name is 'mautic_list_contact_fields' and description states 'List contact fields including custom fields' — both indicate data retrieval without modification."
