## Why mysql_alter_table_add_column is rated Medium

This tool performs a reversible modification to a MySQL database table schema. While the change can be undone (via DROP COLUMN or similar operations), it qualifies as Write rather than Destructive because ALTER TABLE ADD COLUMN is not inherently destructive—it extends the schema without deleting existing data.

From the tool's own definition: "Tool name explicitly contains 'mysql_alter_table_add_column', indicating it modifies database schema by adding a column to an existing table. The 'ALTER TABLE' operation is a write action that modifies table structure."

## Use case

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