WHAT IT DOES

What sheetData does on Mcp Google Sheets

AI agents call sheetData to retrieve information from Mcp Google Sheets without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why sheetData needs a policy

This tool only retrieves or queries existing data from a Google Sheet without performing any side effects, modifications, or irreversible actions. It is a pure read operation that returns data based on specified parameters. The low severity reflects minimal blast radius—worst case is unauthorized data access to a single spreadsheet's cells.

From the tool's definition Tool name 'sheetData' and description states it 'Returns the data present in the specified sheet' with no modification or deletion capabilities. It 'Accepts spreadsheetId, sheet name, range as an argument' to retrieve data.

POLICY

How to control sheetData

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 sheetData:

policy.json

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

sheetData 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.
