WHAT IT DOES

What addSheet does on Google Drive

AI agents use addSheet to create or update resources in Google Drive, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Google Drive environment.

Parameter	Type	Required	Description
`title`	string	Yes	Title for the new sheet/tab
`account`	string	—	Alias of the Google account to target. Optional — defaults to the session/global default account, or the sole authenticated account. Run manage_accounts list to
`spreadsheetId`	string	Yes	Spreadsheet ID

Parameters from the server's own tool schema.

RISK

Why addSheet is rated Medium

Adding a new sheet to a Google Sheet is a data creation action that modifies the spreadsheet structure but is easily undone (sheets can be deleted). This does not permanently destroy data, execute arbitrary code, trigger external side effects, or involve financial transactions. It fits the Write category as a reversible modification.

From the tool's definition Tool description explicitly states it 'adds a new sheet/tab' to a spreadsheet. The verb 'add' and the functional outcome of creating a new sheet constitute a reversible write operation.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs addSheet safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Google Drive, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For addSheet, this is the rule to start with:

addSheet Rate-limited

addSheet 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.

policy.json

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

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Google Drive, apply this rule, and every addSheet call is checked against it from then on.
