RECOMMENDED RULE

The rule that runs fx_basket safely

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

fx_basket Rate-limited

fx_basket 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.
