Update specific cells in an existing row. Args: - doc_id (string): The document ID - table_id (string): The table ID - row_id (string): The row ID - cells (array): Array of {column, value} pairs to update Returns: Request ID confirmation.
AI agents use coda_update_row to create or update resources in Coda MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Coda MCP Server environment.
This tool creates or modifies data reversibly within Coda tables. It updates specific cells in an existing row without deleting data, making it a Write operation. Severity is medium because unauthorized updates could corrupt important document data, but the changes are theoretically reversible (unlike Destructive operations).
From the tool's definition Tool name 'coda_update_row' and description 'Update specific cells in an existing row' directly indicate modification of existing data. The tool accepts row_id, column, and value parameters to perform targeted updates.

Update specific cells in an existing row. Args: - doc_id (string): The document ID - table_id (string): The table ID - row_id (string): The row ID - cells (array): Array of {column, value} pairs to update Returns: Request ID confirmation. It is categorised as a Write tool in the Coda MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Coda MCP Server MCP server in PolicyLayer and add a rule for coda_update_row: 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 Coda MCP Server. Nothing to install.
coda_update_row 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 coda_update_row 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 coda_update_row. 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.
coda_update_row is provided by the Coda MCP Server MCP server (thierryvm/coda-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
