Attacks that exploit this kind of access
The rule that runs ansi_strip safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Gateway, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For ansi_strip, this is the rule to start with:
ansi_strip is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Gateway, apply this rule, and every ansi_strip call is checked against it from then on.
