Attacks that exploit this kind of access
The rule that runs delete_contact safely
PolicyLayer is an MCP gateway: it sits between your AI agents and FavCRM, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For delete_contact, this is the rule to start with:
delete_contact 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 FavCRM, apply this rule, and every delete_contact call is checked against it from then on.
