RECOMMENDED RULE

The rule that runs login safely

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

Any call to login is blocked until a human approves it. The rest of the server keeps working.
