WHAT IT DOES

What insertSheetDimension does on Google Drive

AI agents use insertSheetDimension 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); endIndex - startIndex rows/columns are inserted
`dimension`	string	Yes	Insert rows or columns
`startIndex`	number	Yes	0-based index where the first new row/column goes (inclusive)
`spreadsheetId`	string	Yes	Spreadsheet ID
`inheritFromBefore`	boolean	—	Take formatting from the row/column before the insertion point (default: true when startIndex > 0, else from the one after)

Parameters from the server's own tool schema.

RISK

Why insertSheetDimension is rated Medium

An AI agent can call insertSheetDimension faster than any human can review: one bad instruction and it creates or modifies resources in Google Drive by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

insertSheetDimension Rate-limited

insertSheetDimension 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.

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

FAQ

Questions about insertSheetDimension

What does the insertSheetDimension tool do? +

Insert empty rows or columns at a position in a sheet (one spreadsheets.batchUpdate); what is there now moves down (rows) or right (columns), and formulas referring to it follow. Indices are 0-based and the interval is half-open [startIndex, endIndex): to insert 3 rows before row 5 (0-based; the 6th row), pass startIndex: 5, endIndex: 8. To add rows at the end instead, appendSpreadsheetRows is simpler. Fill the new cells afterwards with updateGoogleSheet / batchUpdateGoogleSheetValues. 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 insertSheetDimension accept? +

insertSheetDimension accepts 7 parameters: account, sheetId, endIndex, dimension, startIndex, spreadsheetId, inheritFromBefore. 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 insertSheetDimension? +

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

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

Can I rate-limit insertSheetDimension? +

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

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

insertSheetDimension 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.
