Attacks that exploit this kind of access
The rule that runs explain_topic 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 explain_topic, this is the rule to start with:
explain_topic is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Nitrostack, apply this rule, and every explain_topic call is checked against it from then on.
