WHAT IT DOES

What hideSheetDimension does on Google Drive

AI agents use hideSheetDimension 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.
`endIndex`	number	Yes	0-based end index (exclusive); must be greater than startIndex
`dimension`	string	Yes	Which dimension to hide
`startIndex`	number	Yes	0-based start index (inclusive)
`spreadsheetId`	string	Yes	Spreadsheet ID

Parameters from the server's own tool schema.

RISK

Why hideSheetDimension is rated Medium

This tool creates or modifies data reversibly by toggling the hidden state of columns/rows in a Google Sheet. While it changes the visual presentation and metadata of the sheet, the action is fully reversible (columns/rows can be unhidden), and no data is deleted or permanently lost. The blast radius is limited to formatting changes within a specific sheet.

From the tool's definition The tool description states it 'Hide a range of columns or rows in a sheet (sets hiddenByUser=true)', which modifies the visibility state of sheet dimensions. This is a reversible modification to spreadsheet formatting.

RECOMMENDED RULE

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

hideSheetDimension Rate-limited

hideSheetDimension 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.

}

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 hideSheetDimension call is checked against it from then on.

FAQ

Questions about hideSheetDimension

What does the hideSheetDimension tool do? +

Hide a range of columns or rows in a sheet (sets hiddenByUser=true). Indices are 0-based and the interval is half-open [startIndex, endIndex) — to hide a single column/row at position 5, pass startIndex: 5, endIndex: 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 hideSheetDimension accept? +

hideSheetDimension accepts 6 parameters: account, sheetId, endIndex, dimension, startIndex, spreadsheetId. Required: sheetId, endIndex, dimension, startIndex, spreadsheetId. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on hideSheetDimension? +

Register the Google Drive MCP server in PolicyLayer and add a rule for hideSheetDimension: 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 hideSheetDimension? +

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

Can I rate-limit hideSheetDimension? +

Yes. Add a rate_limit block to the hideSheetDimension 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 hideSheetDimension completely? +

Set action: deny in the PolicyLayer policy for hideSheetDimension. 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 hideSheetDimension? +
