WHAT IT DOES

What prometheus_range_query does on Mcp Control Plane

AI agents call prometheus_range_query to retrieve information from Mcp Control Plane without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why prometheus_range_query is rated Low

Prometheus range queries are read-only operations that retrieve time-series metrics data over a specified time range. This is a pure data retrieval operation with no side effects, modifications, or state changes.

From the tool's definition Tool name 'prometheus_range_query' and description 'Run a Prometheus range query' indicate querying a time-series database for metrics data. Range queries retrieve historical metric data without modifying state.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs prometheus_range_query safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Control Plane, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For prometheus_range_query, this is the rule to start with:

prometheus_range_query Allowed

prometheus_range_query is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

{
  "version": "1",
  "default": "deny",
  "tools": {
    "prometheus_range_query": {}
  }

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Control Plane, apply this rule, and every prometheus_range_query call is checked against it from then on.
