WHAT IT DOES

What check_code_server does on Mcp Nettools

AI agents call check_code_server to retrieve information from Mcp Nettools without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why check_code_server is rated Low

This tool retrieves health status from a code-server instance via a read-only GET request. While code-server itself is an Execute-capable service, this specific tool merely queries its health endpoint and returns a simple status response. The action is non-destructive, non-modifying, and informational only.

From the tool's definition Tool performs a GET request to a health check endpoint (/healthz) that returns status information ('OK'). No modification, deletion, or execution of arbitrary code occurs.
