AI agents call get_driver_number 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 retrieves static reference data (a driver's car number) without side effects. It is purely informational and read-only, similar to a database lookup. No data is created, modified, or destroyed, and no external operations are triggered.
From the tool's definition The tool name 'get_driver_number' and description 'Get the car number for a specific driver' indicate a simple data retrieval operation with no modification, deletion, or execution of code/commands.
Attacks that exploit this kind of access
Get the car number for a specific driver. 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_driver_number: 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_driver_number 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_driver_number 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_driver_number. 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_driver_number 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.
