Deletes rows from a sheet
AI agents call delete_rows to permanently remove resources in Smartsheet MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of rows is irreversible and cannot be undone through normal tool operations. This represents permanent data loss. While not as severe as a financial transaction, the destructive category is appropriate as it destroys data that may be critical to business operations in a Smartsheet context.
From the tool's definition Tool name is 'delete_rows' and description states 'Deletes rows from a sheet'. The verb 'delete' and the irreversible nature of removing rows from a sheet clearly indicate this is a destructive operation.
Attacks that exploit this kind of access
Deletes rows from a sheet. It is categorised as a Destructive tool in the Smartsheet MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Smartsheet 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 Smartsheet 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 Smartsheet MCP Server MCP server (thomaswtwrt/smar-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
