WHAT IT DOES

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

AI agents use enable_filter to create or update resources in Teradata Workload Management (WLM) MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Teradata Workload Management (WLM) MCP Server environment.

THE RISK

Medium Risk

Why enable_filter needs a policy

This is a Write operation because it modifies the state of a filter rule (activation/deactivation), which is reversible and has no permanent deletion or financial impact. Severity is medium because enabling a filter rule affects workload management policy application, which could impact query routing and performance if misconfigured, but changes are not destructive and can be undone.

From the tool's definition Tool description states 'Enable (activate) a previously disabled filter rule' and 'CHANGES REQUIRE ACTIVATION'.

Documented attack patterns abuse exactly the kind of access enable_filter gives an agent:

POLICY

How to control enable_filter

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 enable_filter:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "enable_filter": {
      "limits": [
        {
          "counter": "enable_filter_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

enable_filter stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about enable_filter

What does the enable_filter tool do? +

Enable (activate) a previously disabled filter rule. REQUIRES: ruleset_name, filter_name. CHANGES REQUIRE ACTIVATION. It is categorised as a Write tool in the Teradata Workload Management (WLM) MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on enable_filter? +

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

enable_filter is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit enable_filter? +

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

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

enable_filter 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.
