Cleanup team resources and save state
AI agents call teammate_cleanup to permanently remove resources in Claude Flow — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The term 'cleanup' typically implies irreversible removal or deallocation of resources (agents, pools, state artifacts). While 'save state' suggests some preservation occurs beforehand, the act of cleaning up team resources cannot generally be undone — agents may be terminated, connections dropped, and allocated infrastructure released.
From the tool's definition 'Cleanup team resources' implies removal or deallocation of resources; 'save state' suggests persistence before removal but the cleanup action itself may be irreversible
Attacks that exploit this kind of access
Cleanup team resources and save state. It is categorised as a Destructive tool in the Claude Flow MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Claude Flow MCP server in PolicyLayer and add a rule for teammate_cleanup: 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 Claude Flow. Nothing to install.
teammate_cleanup 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 teammate_cleanup 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 teammate_cleanup. 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.
teammate_cleanup is provided by the Claude Flow MCP server (claude-flow). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
