Why recommend_indexes_account needs a policy

The tool name suggests it may recommend indexes for an account, which would likely be a Read operation. However, with no description available, it's difficult to determine the exact behavior. Lowering confidence accordingly. If it only recommends (read/analyze), it would be Read. Given the ambiguity, classifying as Other with low confidence.

From the tool's definition Tool name is 'recommend_indexes_account' and description is empty or uninformative.

POLICY

How to control recommend_indexes_account

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "recommend_indexes_account": {
      "limits": [
        {
          "counter": "recommend_indexes_account_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

recommend_indexes_account gets a rate cap, and everything else on the server is denied unless you say otherwise.

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