Part of the Google Super MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use GOOGLESUPER_ADD_SHEET to create or modify resources in Google Super. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call GOOGLESUPER_ADD_SHEET repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Google Super.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Adds a new sheet (worksheet) to a spreadsheet. Use this tool to create a new tab within an existing Google Sheet, optionally specifying its title, index, size, and other properties. IMPORTANT: - Always provide the spreadsheetId. Use 'Search Spreadsheets' action if you need to find it by name - Sheet names must be unique within the spreadsheet - For tab colors, use EITHER rgbColor OR themeColor, never both - Index must be less than or equal to the current number of sheets - CONCURRENCY WARNING: Do not use 'index' when creating multiple sheets in parallel - this causes 'index is too high' errors. For parallel creation, omit the index field and let sheets be added at the end Common use cases: - Add a new sheet with a specific name - Insert a sheet at a specific position - Create a sheet with custom colors and formatting. It is categorised as a Write tool in the Google Super MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Add a rule in your Intercept YAML policy under the tools section for GOOGLESUPER_ADD_SHEET. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Google Super MCP server.
GOOGLESUPER_ADD_SHEET is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the GOOGLESUPER_ADD_SHEET rule in your Intercept 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.
Set action: deny in the Intercept policy for GOOGLESUPER_ADD_SHEET. 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.
GOOGLESUPER_ADD_SHEET is provided by the Google Super MCP server (googlesuper). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
