WHAT IT DOES

What trash_file does on AirMCP

AI agents call trash_file 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.

RISK

Why trash_file is rated Critical

Moving to Trash is a precursor to permanent deletion and constitutes a destructive action. An AI agent misusing this could move critical files to Trash, and if Trash is subsequently emptied (manually or automatically), data would be permanently lost. The blast radius is high as entire folders could be affected.

From the tool's definition 'Move a file or folder to the Trash' — moves files/folders to Trash, which is a deletion action that removes data from its original location.

RECOMMENDED RULE

The rule that runs trash_file 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 trash_file, this is the rule to start with:

trash_file Hidden

trash_file 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 trash_file call is checked against it from then on.
