AI agents call delete_table_column to permanently remove resources in Docx_MCP_cj — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes table columns from Word documents without the ability to undo the operation through the tool itself. Deletion of data is irreversible and constitutes a destructive action. While the blast radius is limited to document structure rather than system-wide, the permanent data loss justifies 'high' severity.

{
"version": "1",
"default": "deny",
"hide": [
"delete_table_column"
]
}delete_table_column disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
