Use to list webhook subscriptions. Webhooks deliver real-time event notifications to your HTTPS endpoint.
AI agents call list_webhooks to retrieve information from Rentalot MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and returns existing webhook subscription data. It retrieves information about configured webhooks without creating, modifying, deleting, or triggering any webhooks. The action is purely informational with no side effects, fitting the 'Read' category. Severity is low because listing webhooks reveals configuration details but does not directly expose sensitive data or enable harmful operations.
From the tool's definition Tool name is 'list_webhooks' and description states 'Use to list webhook subscriptions' — a retrieval operation with no modification, deletion, or execution of external actions.
