WHAT IT DOES

What server_health does on Mcp Control Plane

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.

RISK

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 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.

RECOMMENDED RULE

The rule that runs server_health 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 server_health, this is the rule to start with:

server_health Allowed

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

View as policy code

policy.json

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

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 server_health call is checked against it from then on.
