AI agents call pushonly_policy to retrieve information from UnClick without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns API guardrails/policy information without executing code, modifying data, or performing side effects. It is a read-only operation that queries existing policy definitions. The explicit disclaimer about 'no execution or source-of-truth writes' confirms it does not modify systems.
From the tool's definition Tool description states it "Return[s] the PinballWake PushOnlyAPI guardrails" and explicitly specifies "no execution or source-of-truth writes." The function is to retrieve and return policy/guardrail information.
Attacks that exploit this kind of access
Return the PinballWake PushOnlyAPI guardrails. This blue push lane turns verified IgniteOnly wake packets into worker-facing push envelopes only; no execution or source-of-truth writes. It is categorised as a Read tool in the UnClick MCP Server, which means it retrieves data without modifying state.
Register the UnClick MCP server in PolicyLayer and add a rule for pushonly_policy: 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 UnClick. Nothing to install.
pushonly_policy is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the pushonly_policy 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.
Set action: deny in the PolicyLayer policy for pushonly_policy. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
pushonly_policy is provided by the UnClick MCP server (@unclick/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
