AI agents call servicenow_list_attachments to retrieve information from Servicenow without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries attachment metadata without any side effects. It performs no writes, deletions, code execution, or financial operations. The blast radius of misuse is minimal—an attacker could enumerate attachments across records but cannot modify, delete, or execute anything. Classification as Read is appropriate.
From the tool's definition Tool description states 'List file attachments' and returns 'Attachment metadata including filename, content type, size, and download link'. The action is purely retrieval with no modification, creation, deletion, or execution capabilities.
