WHAT IT DOES

What jobs_get_custom_field_types does on ServiceTitan MCP Server

RISK

Why jobs_get_custom_field_types is rated Low

Despite the empty description, the naming convention strongly suggests this tool retrieves custom field type metadata for jobs without modifying data. The 'get' verb is consistently used across this MCP server for read-only operations. The lack of destructive keywords (delete, drop, etc.) and the context of querying field type definitions (metadata retrieval) indicate minimal blast radius if misused by an AI agent.

From the tool's definition Tool name 'jobs_get_custom_field_types' contains the verb 'get', which indicates data retrieval. The sibling tools on this server follow a pattern of _get, _get_list, and _update operations, consistent with CRUD read operations.
