delete_file
AI agents call delete_file to permanently remove resources in Looker MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool performs an irreversible deletion operation on files within Looker. Even without a description, 'delete' is a destructive keyword indicating data cannot be recovered. This is more severe than Write or Execute. Within a Looker instance managing dashboards, reports, and business intelligence content, file deletion could impact multiple users and workflows.
From the tool's definition Tool name is 'delete_file' with no description provided. The name and server context (Looker content management) indicate irreversible deletion of data.
Attacks that exploit this kind of access
delete_file. It is categorised as a Destructive tool in the Looker MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Looker MCP Server MCP server in PolicyLayer and add a rule for delete_file: 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 Looker MCP Server. Nothing to install.
delete_file 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 delete_file 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 delete_file. 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.
delete_file is provided by the Looker MCP Server MCP server (ultrathink-solutions/looker-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
