RECOMMENDED RULE

The rule that runs rag_optimize_retrieval safely

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

rag_optimize_retrieval Rate-limited

rag_optimize_retrieval 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.
