Clear the geolocation cache
AI agents call clearGeoCache to permanently remove resources in Mcp Helper Tools — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Clearing a cache permanently removes stored data without a recovery mechanism. While the data can be re-fetched, the cached entries themselves are irreversibly destroyed. Blast radius is medium since it only affects a local/application cache rather than primary data stores.
From the tool's definition 'Clear the geolocation cache' — the word 'clear' implies irreversible deletion of cached geolocation data
Attacks that exploit this kind of access
Clear the geolocation cache. It is categorised as a Destructive tool in the Mcp Helper Tools MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Mcp Helper Tools MCP server in PolicyLayer and add a rule for clearGeoCache: 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 Mcp Helper Tools. Nothing to install.
clearGeoCache 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 clearGeoCache 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 clearGeoCache. 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.
clearGeoCache is provided by the Mcp Helper Tools MCP server (missionsquad/mcp-helper-tools). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
