Attacks that exploit this kind of access

RECOMMENDED RULE

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

register_server Rate-limited

register_server stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. 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 register_server call is checked against it from then on.
