AI agents call get_circuit_info to retrieve information from F1 without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries static circuit data without creating, modifying, or deleting anything. It has no side effects and presents no risk of unintended harm if invoked by an AI agent. The blast radius is minimal—worst case, an agent receives stale or irrelevant circuit data for analysis.
From the tool's definition Tool retrieves circuit information (corner positions, marshal lights, marshal sectors) with no modification capability. The verb 'Get' and the nature of the data (static circuit metadata) indicate a read-only operation.
Attacks that exploit this kind of access
Get circuit corner positions, marshal lights, and marshal sectors. It is categorised as a Read tool in the F1 MCP Server, which means it retrieves data without modifying state.
Register the F1 MCP server in PolicyLayer and add a rule for get_circuit_info: 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 F1. Nothing to install.
get_circuit_info 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 get_circuit_info 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 get_circuit_info. 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.
get_circuit_info is provided by the F1 MCP server (luffy610/f1-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
