What props_delete_collection does on Propresenter
AI agents call props_delete_collection to permanently remove resources in Propresenter, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why props_delete_collection is rated Critical
The tool performs an irreversible deletion operation on prop collections in ProPresenter 7. Even though the blast radius is limited to presentation props rather than critical system data, deletion of collections cannot be undone and represents loss of user work. This meets the Destructive category definition: 'irreversibly deletes or overwrites data, or actions that cannot be undone.'
From the tool's definition Tool name contains 'delete' and description states 'Delete a specific prop collection' — this is an irreversible removal of data.
Attacks that exploit this kind of access
The rule that runs props_delete_collection safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Propresenter, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For props_delete_collection, this is the rule to start with:
props_delete_collection 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 Propresenter, apply this rule, and every props_delete_collection call is checked against it from then on.
