RECOMMENDED RULE

The rule that runs update_pinterest_pin safely

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

update_pinterest_pin Rate-limited

update_pinterest_pin 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.
