WHAT IT DOES

What setColumnWidth does on Google Drive

AI agents use setColumnWidth 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
`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
`sheetId`	number	Yes	Sheet ID (from getSpreadsheetInfo / listSheets). The default first sheet is usually 0.
`endColumn`	number	Yes	0-based end column index (exclusive); must be greater than startColumn
`pixelSize`	number	Yes	Column width in pixels (must be >= 0)
`startColumn`	number	Yes	0-based start column index (inclusive)
`spreadsheetId`	string	Yes	Spreadsheet ID

Parameters from the server's own tool schema.

RISK

Why setColumnWidth is rated Medium

setColumnWidth modifies spreadsheet metadata (column dimensions) but does not create, delete, or destroy data. The change is completely reversible—column widths can be adjusted again or reset. This is a Write operation with low severity because it affects only formatting/presentation properties with no data loss risk and minimal business impact.

From the tool's definition Tool description explicitly states it modifies column width in a spreadsheet sheet: 'Set the width (in pixels) of one or more columns in a sheet.' This is a reversible formatting change.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

setColumnWidth Rate-limited

setColumnWidth 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": {
    "setColumnWidth": {
      "limits": [
        {
          "counter": "setcolumnwidth_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 setColumnWidth call is checked against it from then on.

FAQ

Questions about setColumnWidth

What does the setColumnWidth tool do? +

Set the width (in pixels) of one or more columns in a sheet. Indices are 0-based and the interval is half-open [startColumn, endColumn) — to resize a single column at position 5, pass startColumn: 5, endColumn: 6. It is categorised as a Write tool in the Google Drive MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does setColumnWidth accept? +

setColumnWidth accepts 6 parameters: account, sheetId, endColumn, pixelSize, startColumn, spreadsheetId. Required: sheetId, endColumn, pixelSize, startColumn, spreadsheetId. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on setColumnWidth? +

Register the Google Drive MCP server in PolicyLayer and add a rule for setColumnWidth: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Google Drive. Nothing to install.

What risk level is setColumnWidth? +

setColumnWidth is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit setColumnWidth? +

Yes. Add a rate_limit block to the setColumnWidth rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block setColumnWidth completely? +

Set action: deny in the PolicyLayer policy for setColumnWidth. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides setColumnWidth? +

setColumnWidth is provided by the Google Drive MCP server (@ark7/google-drive-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
