WHAT IT DOES

What server_status does on MCP Data Visualization Server

AI agents call server_status to retrieve information from MCP Data Visualization Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why server_status needs a policy

This is a non-destructive information retrieval tool. It queries the server for health metrics and status data, producing no side effects, no data modifications, and no external operations. It falls squarely into the Read category with low severity due to minimal impact if misused—an agent could at worst spam status checks, which has negligible blast radius.

From the tool's definition Tool name 'server_status' and description 'Get server status and health information' indicate a query operation that retrieves diagnostic data without modifying state or triggering external operations.

POLICY

How to control server_status

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Data Visualization Server, and nothing reaches the server without passing your rules. This is the rule we recommend for server_status:

policy.json

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

server_status is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register MCP Data Visualization Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
