WHAT IT DOES

What abort_sessions_user does on Teradata Workload Management (WLM) MCP Server

AI agents call abort_sessions_user to permanently remove resources in Teradata Workload Management (WLM) MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

THE RISK

Critical Risk

Why abort_sessions_user needs a policy

The tool irreversibly kills all active sessions and running queries for a user. Terminated sessions and aborted queries cannot be undone — any in-flight work is lost. The blast radius is critical because misuse could disrupt an entire user's workload or accidentally target the wrong user, causing widespread data processing interruption.

From the tool's definition TERMINATES all active sessions for a specified user. This immediately kills all running queries for that user.

POLICY

How to control abort_sessions_user

PolicyLayer is an MCP gateway — it sits between your AI agents and Teradata Workload Management (WLM) MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for abort_sessions_user:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "abort_sessions_user"
  ]
}

abort_sessions_user disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
