Remove a label from the registry.
AI agents call unregister to permanently remove resources in Teammate — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Unregistering a label from the registry is an irreversible deletion of a registry entry. Once removed, the label mapping is gone and other tools that depend on it (like ask, ask_claude, ask_codex) may lose the ability to route messages to that pane. This constitutes a destructive, non-reversible modification to system state.

Attacks that exploit this kind of access
Remove a label from the registry. It is categorised as a Destructive tool in the Teammate MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Teammate MCP server in PolicyLayer and add a rule for unregister: 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 Teammate. Nothing to install.
unregister 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 unregister 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 unregister. 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.
unregister is provided by the Teammate MCP server (jonghklee/teammate-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
