mysql_alter_table_drop_column

THE RISK

Critical Risk

Dropping a column from a database table is a destructive, irreversible operation. All data stored in that column is permanently lost, and any dependent queries, views, or application code referencing that column will break. This cannot be undone without a prior backup.

From the tool's definition 'Drop a column from an existing table' — dropping a column is an irreversible schema change that permanently removes the column and all its data.

HOW TO CONTROL MYSQL_ALTER_TABLE_DROP_COLUMN

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Windows, and nothing reaches the server without passing your rules. This is the rule we recommend for mysql_alter_table_drop_column:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "mysql_alter_table_drop_column"
  ]
}

mysql_alter_table_drop_column disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Mcp Windows — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
