RECOMMENDED RULE

The rule that runs tools_fierce safely

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

tools_fierce Rate-limited

tools_fierce stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
