## Facts

- Tool: `prometheus_query`
- Server: Mcp Control Plane (`albertik322-sudo/mcp-control-plane`) — https://policylayer.com/tools/mcp-control-plane.md
- Homepage: https://github.com/albertik322-sudo/mcp-control-plane
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Allowed

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "prometheus_query",
    "arguments": {}
  }
}
```

## Why prometheus_query is rated Low

Prometheus queries retrieve time-series metrics and observability data without side effects. Even though 'Execute' might seem applicable because a query is technically 'executed,' the tool's purpose is data retrieval, not arbitrary code execution or system operation invocation. The blast radius is limited to information disclosure of metrics the requester is already authorized to access.

From the tool's own definition: "Tool name 'prometheus_query' and description 'Run an instant Prometheus query' indicate retrieval of metrics data from Prometheus. Query execution against a metrics database is a read-only operation with no data modification or deletion."

## Use case

AI agents call prometheus_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.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Mcp Control Plane:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "prometheus_query": {}
  }
}
```
