RECOMMENDED RULE

The rule that runs fin_receitas safely

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

fin_receitas Rate-limited

fin_receitas gets a rate cap, and everything else on the server is denied unless you say otherwise.
