# get_metrics

Get a DenkOps project's request metrics (latency percentiles, error rate), latest resource sample, and rejected-request count over the last 24h.

- Recommended policy verdict: Allowed

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `project_id` | string | yes |  |

Parameters from the server's own tool schema.

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "get_metrics",
    "arguments": {
      "project_id": "<project_id>"
    }
  }
}
```

## Why get_metrics is rated Low

This tool only queries and retrieves monitoring/observability data about a DenkOps project. It performs no mutations, executions, deletions, or financial operations. The data returned is read-only diagnostic information used for understanding system performance over the last 24 hours. The blast radius of misuse is minimal—an attacker gains visibility into performance metrics but cannot alter infrastructure or data.

From the tool's own definition: "Tool name 'get_metrics' and description explicitly states it retrieves metrics (latency percentiles, error rate, resource samples, rejected-request counts) with no modification or side effects implied."

## Use case

AI agents call get_metrics to retrieve information from Denkopsai 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 Denkopsai:

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

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
