RECOMMENDED RULE

The rule that runs crypto_compare safely

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

crypto_compare Allowed

crypto_compare is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
