REQUIRED for cleaning up old cached media files (images and videos) and freeing disk space. Use this tool when users want to remove old cached media, clean up storage space, or when cache becomes too large. Essential for cache maintenance and storage management.
AI agents call cleanup_media_cache to permanently remove resources in Google Ads MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes cached data. While the data is recoverable through re-caching, the tool itself performs permanent deletion of stored files. The blast radius is high because an AI agent with unconstrained use could delete substantial cached media without user awareness, disrupting service performance and requiring expensive re-caching operations.
From the tool's definition Tool description explicitly states it removes ('cleaning up', 'remove') 'cached media files (images and videos)' and 'freeing disk space', operations that are irreversible and cannot be undone without re-caching.
Documented attack patterns abuse exactly the kind of access cleanup_media_cache gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Google Ads MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for cleanup_media_cache:
{
"version": "1",
"default": "deny",
"hide": [
"cleanup_media_cache"
]
}cleanup_media_cache disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

REQUIRED for cleaning up old cached media files (images and videos) and freeing disk space. Use this tool when users want to remove old cached media, clean up storage space, or when cache becomes too large. Essential for cache maintenance and storage management. It is categorised as a Destructive tool in the Google Ads MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Google Ads MCP Server MCP server in PolicyLayer and add a rule for cleanup_media_cache: 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 Google Ads MCP Server. Nothing to install.
cleanup_media_cache 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 cleanup_media_cache 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 cleanup_media_cache. 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.
cleanup_media_cache is provided by the Google Ads MCP Server MCP server (proxy-intell/google-ads-library-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Google Ads MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
