Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs bad-param safely

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

bad-param Rate-limited

bad-param gets a rate cap, and everything else on the server is denied unless you say otherwise.
