  "jsonrpc": "2.0",

## Why f1_get_circuits is rated Low

This tool retrieves static information about Formula 1 racing circuits. The verb 'Get' combined with the read-only nature of querying circuit data (no creation, modification, deletion, or execution of operations) clearly places this in the Read category. The low severity reflects that unauthorized access to publicly available sports data carries minimal blast radius.

From the tool's own definition: "Tool name 'f1_get_circuits' and description 'Get Formula 1 circuits with optional filters' indicates data retrieval with no modification or side effects."

## Use case

AI agents call f1_get_circuits to retrieve information from Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Mcp:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "f1_get_circuits": {}
  }
}
```
