WHAT IT DOES

What create_spreadsheet does on Mcp Google Sheets

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

Parameter	Type	Required	Description
`title`	string	Yes	The spreadsheet title (also the Drive file name).
`locale`	string	—	Spreadsheet locale as ISO code, e.g. "en_US" or "ru_RU" (affects number/date parsing).
`time_zone`	string	—	Time zone in CLDR format, e.g. "Europe/Moscow" (affects NOW()/TODAY()).
`sheet_titles`	array	—	Tab titles to create, in order, e.g. ["Data","Summary"]. Omitted = one default sheet.

Parameters from the server's own tool schema.

RECOMMENDED RULE

The rule that runs create_spreadsheet safely

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

create_spreadsheet Rate-limited

create_spreadsheet 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.

FAQ

Questions about create_spreadsheet

What does the create_spreadsheet tool do? +

Creates a new Google Sheets spreadsheet and returns it: spreadsheetId, spreadsheetUrl, properties (title, locale, timeZone) and sheets[] with each sheet's numeric sheetId. sheet_titles creates one tab per title in order (omitted = a single default "Sheet1"). The file lands in the authorized user's My Drive root — moving it into a folder needs the Drive API, which this server does not cover. Save the returned spreadsheetId: the Sheets API has no list endpoint of its own (search_spreadsheets exists, but it needs a Drive scope on the token). It is categorised as a Write tool in the Mcp Google Sheets MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does create_spreadsheet accept? +

create_spreadsheet accepts 4 parameters: title, locale, time_zone, sheet_titles. Required: title. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on create_spreadsheet? +

Register the Mcp Google Sheets MCP server in PolicyLayer and add a rule for create_spreadsheet: 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 Mcp Google Sheets. Nothing to install.

What risk level is create_spreadsheet? +

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

Can I rate-limit create_spreadsheet? +

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

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

create_spreadsheet is provided by the Mcp Google Sheets MCP server (@a1-x-tech/mcp-google-sheets). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
