WHAT IT DOES

What list_webhook_subscriptions does on instantKOM MCP Server

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

RISK

Why list_webhook_subscriptions is rated Low

This tool performs a read-only operation that queries and returns webhook subscription information. It does not create, modify, delete, or execute any actions. The only potential concern is information disclosure (what webhooks are configured), which is a low-severity read risk in the context of an authenticated user querying their own resources.

From the tool's definition Tool name "list_webhook_subscriptions" and description "List all active webhook subscriptions" indicate a query operation that retrieves existing configuration data without modification or side effects.
