WHAT IT DOES

What services_update does on ServiceTitan MCP Server

AI agents use services_update 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 services_update is rated Medium

Based on the sibling tools pattern (activities_controllers_get, adjustments_update, etc.), this server exposes CRUD operations. The 'update' suffix combined with 'services' indicates a Write operation that modifies data reversibly. While the empty description lowers confidence slightly, the naming convention and context are clear.

From the tool's definition Tool name is 'services_update' with empty description. The 'update' verb indicates modification of existing data.
