WHAT IT DOES

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

AI agents call list_query_band to retrieve information from Teradata Workload Management (WLM) MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

POLICY

How to control list_query_band

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 list_query_band:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_query_band": {}
  }
}

list_query_band is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
