Delete rows from an Excel file based on filters
AI agents call delete_rows to permanently remove resources in Excel MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes data from Excel files with no undo mechanism within the MCP protocol scope. While the deletion is scoped by filters (not entirely blind), the operation is irreversible and constitutes data destruction. This ranks as Destructive rather than Write because deletion cannot be undone.
From the tool's definition Tool name 'delete_rows' combined with description 'Delete rows from an Excel file based on filters' explicitly performs irreversible deletion of data.
Attacks that exploit this kind of access
Delete rows from an Excel file based on filters. It is categorised as a Destructive tool in the Excel MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Excel MCP Server MCP server in PolicyLayer and add a rule for delete_rows: 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 Excel MCP Server. Nothing to install.
delete_rows 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_rows 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_rows. 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_rows is provided by the Excel MCP Server MCP server (tapankumarbarik/python-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
