## Why leads_update is rated Medium

The 'leads_update' tool modifies lead records in a business-critical CRM system (ServiceTitan). While reversible through subsequent updates, this carries high severity because leads represent potential revenue opportunities and client contacts. Unauthorized or erroneous updates could damage business relationships, corrupt customer data, or redirect work opportunities.

From the tool's own definition: "Tool name 'leads_update' indicates modification of lead records. The '_update' suffix clearly denotes a write operation that modifies existing data."

## Use case

AI agents use leads_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.
