## Why arvan_notify_webhook is rated High

This tool sends HTTP POST requests to arbitrary external URLs with arbitrary JSON payloads. This constitutes an external operation/trigger whose effects depend on the arguments — the destination webhook and payload determine what happens. It could be used to trigger any downstream automation, exfiltrate data, or invoke external APIs with unpredictable side effects.

From the tool's own definition: "POST a JSON payload to an arbitrary webhook"

## Use case

AI agents invoke arvan_notify_webhook to trigger actions in ArvanCloud MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
