Delete a user by their ID
AI agents call delete_user to permanently remove resources in MCP Node Js TypeScript API — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes user records from MongoDB without possibility of recovery (unless backups exist outside the tool's control). While the blast radius depends on which user is targeted, the irreversible nature of deletion and the sensitivity of user data warrant a 'high' severity rating. Confidence is very high because the intent is unambiguous.
From the tool's definition Tool name is 'delete_user' with description 'Delete a user by their ID'. The verb 'delete' combined with the explicit purpose of removing a user record indicates irreversible data deletion.
Attacks that exploit this kind of access
Delete a user by their ID. It is categorised as a Destructive tool in the MCP Node Js TypeScript API MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the MCP Node Js TypeScript API 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 MCP Node Js TypeScript API. 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 MCP Node Js TypeScript API MCP server (proffillipesilva/mcpnodefil). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
