Block by default and require explicit approval.
Register the x711 — Universal Agent Gas Station MCP server in PolicyLayer and add a rule for x711_hallucination_pill: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches x711 — Universal Agent Gas Station. Nothing to install.
x711_hallucination_pill is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the x711_hallucination_pill rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
