AI agents call smartsheet_get_columns to retrieve information from Smartsheet MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only query operation that retrieves schema information about a Smartsheet sheet. It performs no modifications, deletions, or execution of external code. The purpose is informational—to obtain column IDs and types for reference by other tools. The blast radius of misuse is minimal; exposing column definitions poses no direct data loss or financial risk.
From the tool's definition Tool description explicitly states 'Retrieve all column definitions' and returns column metadata without modifying any data. The tool only 'gets' information needed for subsequent operations, with no side effects.

It is categorised as a Read tool in the Smartsheet MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Smartsheet MCP Server MCP server in PolicyLayer and add a rule for smartsheet_get_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 Smartsheet MCP Server. Nothing to install.
smartsheet_get_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 smartsheet_get_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 smartsheet_get_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.
smartsheet_get_columns 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.
