Why create_dataset_metric needs a policy

This tool creates new metrics, which are data objects that can be modified or deleted later. Creation is a Write operation—it modifies the dataset's configuration by adding metric definitions, but the action is reversible (metrics can be deleted via the sibling 'delete_dataset_metric' tool).

From the tool's definition Tool name is 'create_dataset_metric' and description states 'Create one or more new metrics for a dataset', indicating it creates new data artifacts within Superset that are reversible.

POLICY

How to control create_dataset_metric

PolicyLayer is an MCP gateway — it sits between your AI agents and Superset, and nothing reaches the server without passing your rules. This is the rule we recommend for create_dataset_metric:

policy.json

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

create_dataset_metric 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.

Create a free account and register Superset — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about create_dataset_metric

What does the create_dataset_metric tool do? +

Create one or more new metrics for a dataset. It is categorised as a Write tool in the Superset MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_dataset_metric? +

Register the Superset MCP server in PolicyLayer and add a rule for create_dataset_metric: 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 Superset. Nothing to install.

What risk level is create_dataset_metric? +

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

Can I rate-limit create_dataset_metric? +

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

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

create_dataset_metric is provided by the Superset MCP server (winding2020/superset-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Superset tool call.

Start from Superset, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
