RECOMMENDED RULE

The rule that runs create_buy_order safely

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

create_buy_order Rate-limited

create_buy_order 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.
