Delete a worker set
AI agents call delete_worker_set to permanently remove resources in Rockfish MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes a worker set, which cannot be undone. Worker sets are infrastructure components in an ML platform that likely support running workflows and models. Deleting a worker set is irreversible data/resource destruction with potentially significant operational impact (jobs may fail, workflows may be interrupted).
From the tool's definition Tool name is 'delete_worker_set' with description 'Delete a worker set'. The verb 'delete' indicates irreversible removal of a resource (a worker set) from the ML platform.
Attacks that exploit this kind of access
Delete a worker set. It is categorised as a Destructive tool in the Rockfish MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Rockfish MCP Server MCP server in PolicyLayer and add a rule for delete_worker_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 Rockfish MCP Server. Nothing to install.
delete_worker_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_worker_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_worker_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_worker_set is provided by the Rockfish MCP Server MCP server (wolfdancer/rockfish-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
