WHAT IT DOES

What appointments_add does on ServiceTitan MCP Server

AI agents use appointments_add 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 appointments_add is rated Medium

The 'add' action in the context of a service business API (ServiceTitan manages scheduling, appointments, and service operations) indicates creation of appointment records. This modifies business-critical data (scheduling system) but is reversible (appointments can be deleted/modified). Categorized as Write rather than Execute because it creates structured data records rather than triggering arbitrary operations.

From the tool's definition Tool name 'appointments_add' indicates creation of new appointment records. No description provided, but the naming pattern 'add' combined with sibling tools showing CRUD operations (get, get_list, update) on ServiceTitan API (business management platform)…

RECOMMENDED RULE

The rule that runs appointments_add safely

appointments_add Rate-limited

appointments_add 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.
