Delete a permission set. This action cannot be undone.
AI agents call delete_permission_set 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.
Deleting a permission set is an irreversible action that permanently removes access control configurations. While the blast radius is limited to permission management rather than data or financial systems, the inability to undo the operation and the potential impact on user access control justifies the Destructive category and high severity.
From the tool's definition Tool name is 'delete_permission_set' and description explicitly states 'This action cannot be undone.' The verb 'delete' combined with the irreversible nature confirms destructive classification.
Attacks that exploit this kind of access
Delete a permission set. This action cannot be undone. 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_permission_set: 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_permission_set 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_permission_set 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_permission_set. 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_permission_set 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.
