AI agents call clearCache to permanently remove resources in Formula1 MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The name 'clearCache' strongly suggests this tool deletes/purges cached data, which is an irreversible action (cached data is lost). However, the description is empty and uninformative, so confidence is reduced. In the context of an F1 data server, clearing the cache would remove stored race/timing data, requiring it to be re-fetched.
From the tool's definition Tool name 'clearCache' implies irreversible deletion of cached data
Documented attack patterns abuse exactly the kind of access clearCache gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Formula1 MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for clearCache:
{
"version": "1",
"default": "deny",
"hide": [
"clearCache"
]
}clearCache disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

clearCache. It is categorised as a Destructive tool in the Formula1 MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Formula1 MCP Server MCP server in PolicyLayer and add a rule for clearCache: 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 Formula1 MCP Server. Nothing to install.
clearCache 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 clearCache 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 clearCache. 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.
clearCache is provided by the Formula1 MCP Server MCP server (panth1823/formula1-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Formula1 MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
