Why spreadsheetInfo needs a policy

This tool only reads and returns information about a spreadsheet. It accepts a spreadsheetId and returns metadata. There are no side effects, no data modification, and no destructive actions. It is a straightforward read/query operation with minimal blast radius.

From the tool's definition 'Gives info about the spreadsheet' — retrieves metadata about a spreadsheet by its ID, no modification implied

How to control spreadsheetInfo

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "spreadsheetInfo": {}
  }
}

spreadsheetInfo is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Mcp Google Sheets — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
