WHAT IT DOES

What cancel_invitation does on Businys

AI agents call cancel_invitation 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 cancel_invitation is rated Critical

Cancelling an invitation is an irreversible action — the invitation token/record is invalidated and cannot be 'uncancelled'. The 'Owner only' restriction indicates it is a privileged, non-trivial operation. While the blast radius is moderate (limited to the specific invitation), the action cannot be undone, placing it in the Destructive category.

From the tool's definition Cancel a pending invitation. Owner only.

RECOMMENDED RULE

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

cancel_invitation Hidden

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