WHAT IT DOES

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

AI agents invoke activate_ruleset to trigger actions in Teradata Workload Management (WLM) MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

THE RISK

High Risk

Why activate_ruleset needs a policy

Activating a ruleset pushes all accumulated configuration changes into a live production system immediately. This is an irreversible trigger of potentially wide-ranging system-level changes (throttles, filters, workload rules) affecting all active sessions and workloads. It is not merely a write (config staging) but an execution trigger with immediate, broad blast radius on a production Teradata environment.

From the tool's definition ACTIVATE a ruleset to apply ALL pending configuration changes to the live system. IMMEDIATE EFFECT.

POLICY

How to control activate_ruleset

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 activate_ruleset:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "activate_ruleset": {
      "limits": [
        {
          "counter": "activate_ruleset_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

activate_ruleset stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about activate_ruleset

What does the activate_ruleset tool do? +

ACTIVATE a ruleset to apply ALL pending configuration changes to the live system. MUST BE CALLED after any create, modify, enable, disable, or delete operations. REQUIRES: ruleset_name. IMMEDIATE EFFECT. It is categorised as a Execute tool in the Teradata Workload Management (WLM) MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on activate_ruleset? +

Register the Teradata Workload Management (WLM) MCP Server MCP server in PolicyLayer and add a rule for activate_ruleset: 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 activate_ruleset? +

activate_ruleset is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit activate_ruleset? +

Yes. Add a rate_limit block to the activate_ruleset 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 activate_ruleset completely? +

Set action: deny in the PolicyLayer policy for activate_ruleset. 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 activate_ruleset? +

activate_ruleset 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.
