Delete a column by header name or letter.
AI agents call delete_column to permanently remove resources in Google Connections — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a column in a spreadsheet irreversibly removes all data in that column and cannot be undone through normal tool operations. This is a destructive action that meets the criteria for the Destructive category. While the blast radius is limited to a single spreadsheet (not organization-wide), the permanent data loss justifies 'high' severity.
From the tool's definition Tool name 'delete_column' explicitly performs a delete operation on spreadsheet columns. Description states 'Delete a column by header name or letter,' confirming irreversible removal of data.
Attacks that exploit this kind of access
Delete a column by header name or letter. It is categorised as a Destructive tool in the Google Connections MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Google Connections MCP server in PolicyLayer and add a rule for delete_column: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Google Connections. Nothing to install.
delete_column is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_column rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for delete_column. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
delete_column is provided by the Google Connections MCP server (michaelzrork/google-connections-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
