WHAT IT DOES

What ArrivalWindows_Activated does on ServiceTitan MCP Server

AI agents use ArrivalWindows_Activated to create or update resources in ServiceTitan MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ServiceTitan MCP Server environment.

RISK

Why ArrivalWindows_Activated is rated Medium

The tool name implies toggling or activating arrival windows, a reversible configuration change in a service management system. Without a description, confidence is reduced, but the naming pattern and server context (ServiceTitan handles field service operations) suggest this creates or modifies scheduling/availability settings rather than destructively deleting or executing arbitrary operations.

From the tool's definition Tool name 'ArrivalWindows_Activated' suggests activation/enablement of arrival windows, which modifies state. Description is empty, limiting certainty.

Attacks that exploit this kind of access

ArrivalWindows_Activated Rate-limited

ArrivalWindows_Activated stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
