WHAT IT DOES

What customer_memberships_create does on ServiceTitan MCP Server

AI agents use customer_memberships_create 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 customer_memberships_create is rated Medium

This tool creates new membership records for customers, which modifies customer data in the ServiceTitan system. While reversible (hence Write rather than Destructive), it could impact customer billing cycles, access levels, or service entitlements if misused by an AI agent. The empty description lowers confidence slightly, but the 'create' verb in the name clearly indicates a write operation.

From the tool's definition Tool name 'customer_memberships_create' explicitly indicates creation of new customer membership records. No destructive or financial keywords present, and the operation is reversible (memberships can be updated or removed).
