An AI agent can call recommend_purchase faster than any human can review: one bad instruction and it creates or modifies resources in Nitrostack by the hundred, each call as confident as the last.

RECOMMENDED RULE

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

recommend_purchase Rate-limited

recommend_purchase 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.
