## Why built_in_variables_enable is rated Medium

This tool modifies GTM workspace configuration by enabling built-in variables, which is a reversible operation (variables can be disabled). It does not delete data, execute arbitrary code, move money, or cause permanent damage. The severity is medium because enabling variables could affect tracking behavior or expose data collection mechanisms, but the change is non-destructive and can be reversed.

From the tool's own definition: "Tool description explicitly marks this as [WRITE] and states it 'Enable[s] one or more built-in variables in a GTM workspace,' which creates or modifies configuration state in Google Tag Manager."

## Use case

AI agents use built_in_variables_enable to create or update resources in Samarth Gtm Mcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Samarth Gtm Mcp environment.
