What pages_set_body_text does on AirMCP
AI agents use pages_set_body_text to create or update resources in AirMCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AirMCP environment.
Why pages_set_body_text is rated Medium
This tool modifies existing content in a Pages document (Apple's word processor). While the change is reversible (undo/version history), it can overwrite significant user work without warning if invoked by an agent. The severity is high because Pages documents often contain important personal or professional content.
From the tool's definition Tool name 'pages_set_body_text' and description 'Replace the body text of an open Pages document' explicitly indicate modification of document content. The verb 'Replace' confirms reversible alteration of data.
