Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs delete_message safely

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

delete_message Hidden

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