List all columns in a Coda table, including their IDs and types. Useful to get column IDs before reading/writing rows, since Coda rows use column IDs as keys. Args: - doc_id (string): The document ID - table_id (string): The table ID or name - response_format:
AI agents call coda_list_columns to retrieve information from Coda MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about table columns without creating, modifying, or deleting any data. It is a pure read operation that returns information needed for subsequent operations. The severity is low because listing columns causes no harm and has minimal blast radius if invoked incorrectly.
From the tool's definition Tool name is 'coda_list_columns' and description states it 'List all columns in a Coda table, including their IDs and types.' The description explicitly notes it is used 'to get column IDs before reading/writing rows' — a retrieval/query operation with no…

List all columns in a Coda table, including their IDs and types. Useful to get column IDs before reading/writing rows, since Coda rows use column IDs as keys. Args: - doc_id (string): The document ID - table_id (string): The table ID or name - response_format:. It is categorised as a Read tool in the Coda MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Coda MCP Server MCP server in PolicyLayer and add a rule for coda_list_columns: 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_list_columns is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the coda_list_columns 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_list_columns. 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_list_columns 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.
