Why drive_getFileContent needs a policy

This tool retrieves and reads file data from Google Drive. It exports documents in standard formats (text, CSV) but does not create, modify, delete, or execute any operations. The action is purely informational with no blast radius beyond unauthorized data access to files the authenticated user can already access.

From the tool's definition Tool name 'drive_getFileContent' and description 'Get the content of a file. Exports Google Docs/Sheets as text/csv' indicate retrieval of file content with no modification, deletion, or side effects.

POLICY

How to control drive_getFileContent

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

policy.json

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

drive_getFileContent 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 Google MCP Remote — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
