WHAT IT DOES

What addDataValidation does on Google Drive

AI agents use addDataValidation 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
`range`	string	Yes	A1 range
`strict`	boolean	—	Reject invalid values
`values`	array	Yes	Condition values (e.g. list items, threshold). For ONE_OF_RANGE: exactly one value, the source range in A1 notation (e.g. 'Reference!A2:A50'); a leading '=' is
`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
`showCustomUi`	boolean	—	Show dropdown/custom UI
`conditionType`	string	Yes	Validation condition type. ONE_OF_RANGE creates a dropdown sourced from a cell range in the same spreadsheet, so the list can be maintained in one place (or imp
`spreadsheetId`	string	Yes	Spreadsheet ID

Parameters from the server's own tool schema.

RISK

Why addDataValidation is rated Medium

This tool modifies spreadsheet properties (data validation rules) but does not delete data, execute arbitrary code, or cause destructive effects. It is categorized as Write because it creates or modifies spreadsheet metadata/configurations reversibly.

From the tool's definition Tool name 'addDataValidation' and description 'Add data validation rules to a sheet range' indicate modification of spreadsheet configurations. This creates or modifies validation rules on existing data ranges, which is a reversible write operation.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs addDataValidation 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 addDataValidation, this is the rule to start with:

addDataValidation Rate-limited

addDataValidation 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.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "addDataValidation": {
      "limits": [
        {
          "counter": "adddatavalidation_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 addDataValidation call is checked against it from then on.
