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

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

## Why server_health is rated Low

This tool retrieves and returns health information about a server (metrics, status, diagnostics). It is a read-only operation that queries existing data without creating, modifying, deleting, executing code, or performing financial operations. The blast radius of misuse is minimal since it only exposes observability data about system health.

From the tool's own definition: "Tool named 'server_health' with description 'Return a practical health bundle for the Ubuntu server' indicates querying and retrieving server health metrics/status data with no modification or side effects."

## Use case

AI agents call server_health 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": {
    "server_health": {}
  }
}
```

## 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`
