Update one or more existing rows in a Smartsheet sheet. Each row update specifies the row ID and cells to change. Only provided cells are updated; unspecified cells are left unchanged. Can also lock/unlock rows or change hierarchy. Args: - sheet_id (number): Target sheet ID - rows (array): Array ...
AI agents use smartsheet_update_rows to create or update resources in Smartsheet MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Smartsheet MCP Server environment.
The tool modifies existing data in a Smartsheet sheet by updating cell values, row locks, and hierarchy—all reversible operations. This qualifies as Write category. Severity is medium because bulk row updates could affect substantial data sets and dependent workflows, but the changes are not destructive and can be undone.
From the tool's definition Tool description states 'Update one or more existing rows in a Smartsheet sheet' and 'Only provided cells are updated; unspecified cells are left unchanged.' This is clearly a modification operation.
Attacks that exploit this kind of access
Update one or more existing rows in a Smartsheet sheet. Each row update specifies the row ID and cells to change. Only provided cells are updated; unspecified cells are left unchanged. Can also lock/unlock rows or change hierarchy. Args: - sheet_id (number): Target sheet ID - rows (array): Array of row update objects, each containing: - row_id (number): ID of the row to update - cells (array): Array of {column_id, value} cells to update - locked (boolean, optional): Lock or unlock the row - expanded (boolean, optional): Expand or collapse row Returns: Updated row data and new sheet version. It is categorised as a Write tool in the Smartsheet MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Smartsheet MCP Server MCP server in PolicyLayer and add a rule for smartsheet_update_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.
smartsheet_update_rows is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the smartsheet_update_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 smartsheet_update_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.
smartsheet_update_rows is provided by the Smartsheet MCP Server MCP server (prmbr42-bot/smartsheet-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
