## Why databricks_start_app is rated High

Starting an application is an Execute action—it triggers an external operation whose effects depend on which app is started and its configuration. While not irreversible (apps can be stopped), it initiates computational or service operations that may consume resources or interact with external systems.

From the tool's own definition: "Tool name 'databricks_start_app' indicates starting/launching an application. The sibling tools on this server (databricks_create_app, databricks_cancel_run, databricks_create_cluster) establish this is a Databricks operations server where 'start' actions…"

## Use case

AI agents invoke databricks_start_app to trigger actions in Databricks MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
