Why create_sheet_in_workspace needs a policy

This tool creates a new sheet, which is a reversible write operation. It modifies the workspace by adding a new document but does not execute arbitrary code, delete data, or move funds. The blast radius is medium because creating sheets in a shared workspace could impact collaboration or consume storage resources, but the action is easily undone by deletion.

From the tool's definition Tool name 'create_sheet_in_workspace' and description 'Create a sheet in a workspace' indicate creation of new data/resources in Smartsheet.

POLICY

How to control create_sheet_in_workspace

PolicyLayer is an MCP gateway — it sits between your AI agents and Smartsheet MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_sheet_in_workspace:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_sheet_in_workspace": {
      "limits": [
        {
          "counter": "create_sheet_in_workspace_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_sheet_in_workspace stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
