Delete a user. user_id: from list_users
AI agents call delete_user to permanently remove resources in Morpheus MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a user account is a destructive operation that cannot be undone and results in permanent removal of identity and access control from the Morpheus infrastructure management system. This impacts user access, audit trails, and system security. While not financial, it is more severe than Execute or Write operations due to its irreversible nature.
From the tool's definition Tool name is 'delete_user' and description states 'Delete a user', which is an irreversible action that removes user accounts from the system.
Attacks that exploit this kind of access
Delete a user. user_id: from list_users. It is categorised as a Destructive tool in the Morpheus MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Morpheus MCP Server MCP server in PolicyLayer and add a rule for delete_user: 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 Morpheus MCP Server. Nothing to install.
delete_user 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_user 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_user. 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_user is provided by the Morpheus MCP Server MCP server (nixndme/morpheus-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
delete_user is one line of Morpheus MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
