## Why servicetitan_list_customers is rated Low

This tool queries and retrieves customer data without creating, modifying, deleting, or executing operations. The optional filters are query parameters, not actions. Misuse would at worst expose customer information, a read-access risk rather than a write, execute, or destructive one.

From the tool's own definition: "Tool name is 'list_customers' and description states 'List all customers with optional filters' — classic data retrieval operation with no modification or side effects."

## Use case

AI agents call servicetitan_list_customers to retrieve information from ServiceTitan MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

```json
{
  "version": "1",
