Add sub-criteria to a target classification for advanced rule targeting. Sub-criteria types: FTSCAN, MINSTEPTIME, MAXSTEPTIME, JOIN, MEMORY. REQUIRES: ruleset_name, rule_name, target_type, target_value, description, subcriteria_type. CHANGES REQUIRE ACTIVATION.
AI agents use add_subcriteria_to_target 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.
This tool creates or modifies rule sub-criteria configuration (FTSCAN, MINSTEPTIME, MAXSTEPTIME, JOIN, MEMORY criteria for workload classification targets). These changes are reversible—they modify rule definitions but require activation and can be undone by removing or modifying the sub-criteria.
From the tool's definition Tool description explicitly states "Add sub-criteria to a target classification" and "CHANGES REQUIRE ACTIVATION", indicating the tool creates or modifies workload management rules configuration that can be reversed (changes are not immediately applied until…
Documented attack patterns abuse exactly the kind of access add_subcriteria_to_target gives an agent:
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 add_subcriteria_to_target:
{
"version": "1",
"default": "deny",
"tools": {
"add_subcriteria_to_target": {
"limits": [
{
"counter": "add_subcriteria_to_target_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add_subcriteria_to_target 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.

Add sub-criteria to a target classification for advanced rule targeting. Sub-criteria types: FTSCAN, MINSTEPTIME, MAXSTEPTIME, JOIN, MEMORY. REQUIRES: ruleset_name, rule_name, target_type, target_value, description, subcriteria_type. 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.
Register the Teradata Workload Management (WLM) MCP Server MCP server in PolicyLayer and add a rule for add_subcriteria_to_target: 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.
add_subcriteria_to_target is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the add_subcriteria_to_target 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.
Set action: deny in the PolicyLayer policy for add_subcriteria_to_target. 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.
add_subcriteria_to_target 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.
Start from Teradata Workload Management (WLM) MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
