What delete_note does on AirMCP
AI agents call delete_note to permanently remove resources in AirMCP, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why delete_note is rated Critical
This tool irreversibly removes user data (notes) from the Apple Notes application. Although there is a 30-day recovery window via Recently Deleted, the action cannot be undone immediately and the data is permanently lost after that period. This qualifies as Destructive rather than Write (which is reversible).
From the tool's definition "Delete a note by ID. The note is moved to Recently Deleted and permanently removed after 30 days." — the tool explicitly deletes notes with permanent removal after 30 days.
Attacks that exploit this kind of access
The rule that runs delete_note safely
PolicyLayer is an MCP gateway: it sits between your AI agents and AirMCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For delete_note, this is the rule to start with:
delete_note is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect AirMCP, apply this rule, and every delete_note call is checked against it from then on.
