Clear server caches.
AI agents call clear_cache to permanently remove resources in Ansible Know — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Clearing caches permanently removes stored data (cached documentation, module info, etc.) that cannot be recovered without re-fetching. This is an irreversible operation fitting the Destructive category.
From the tool's definition 'Clear server caches' — clearing caches is an irreversible action that destroys cached data
Attacks that exploit this kind of access
Clear server caches. It is categorised as a Destructive tool in the Ansible Know MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Ansible Know MCP server in PolicyLayer and add a rule for clear_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 Ansible Know. Nothing to install.
clear_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 clear_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 clear_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.
clear_cache is provided by the Ansible Know MCP server (leogallego/ansible-know-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
