WHAT IT DOES

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

AI agents call list_active_WD 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

Low Risk

Why list_active_WD needs a policy

This tool retrieves and displays information about active workload definitions in the Teradata WLM system. It performs a read-only operation that queries the current state of workloads without creating, modifying, deleting, or executing any changes. The blast radius of misuse is minimal—an agent could only gain visibility into workload configuration, which poses no direct risk to data or systems.

From the tool's definition Tool name is 'list_active_WD' and description states it 'List all currently active workload definitions' and 'Returns workload names, states, and basic configuration.' These are query/retrieval operations with no side effects.

POLICY

How to control list_active_WD

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_active_WD:

policy.json

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

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

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Questions about list_active_WD

What does the list_active_WD tool do? +

List all currently active workload definitions (WD). Workloads are categories that classify and manage different types of queries (e.g., ETL, Reporting, Ad-hoc). Use this to see which workloads are enabled, verify workload configuration, or understand current workload management setup. Returns workload names, states, and basic configuration. It is categorised as a Read tool in the Teradata Workload Management (WLM) MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on list_active_WD? +

Register the Teradata Workload Management (WLM) MCP Server MCP server in PolicyLayer and add a rule for list_active_WD: 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 Teradata Workload Management (WLM) MCP Server. Nothing to install.

What risk level is list_active_WD? +

list_active_WD is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit list_active_WD? +

Yes. Add a rate_limit block to the list_active_WD 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.

How do I block list_active_WD completely? +

Set action: deny in the PolicyLayer policy for list_active_WD. 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.

What MCP server provides list_active_WD? +

list_active_WD is provided by the Teradata Workload Management (WLM) MCP Server MCP server (teradata-labs/mcp-server-teradata-wlm). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
