WHAT IT DOES

What delete_exercise does on Businys

AI agents call delete_exercise to permanently remove resources in Businys, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why delete_exercise is rated Critical

This tool permanently removes exercise data with no undo mechanism. While the blast radius is somewhat limited to a single user's custom exercises (not seed/system exercises), the action is irreversible and constitutes data destruction. Severity is high rather than critical because the impact is scoped to exercise records rather than financial data or critical business information.

From the tool's definition Tool name is 'delete_exercise' and description states 'Delete a custom exercise.' The verb 'delete' indicates irreversible removal of data.

RECOMMENDED RULE

The rule that runs delete_exercise safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Businys, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For delete_exercise, this is the rule to start with:

delete_exercise Hidden

delete_exercise is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
