Google Sheets MCP

No. Google does not ship a first-party Google Sheets MCP server today. There are community-built MCP servers that wrap the Sheets API, but they require a Google Cloud project, a service account JSON key, local Node or Python to run, and are typically single-client. Quadratic MCP offers a simpler path: export your Sheet to Quadratic once and every MCP-compatible AI can work on it.

Download your Google Sheet as .xlsx (File → Download → Microsoft Excel), drop it into Quadratic, then install the Quadratic MCP server in your AI client of choice — ChatGPT, Claude, Cursor, VS Code, and more. Your AI can now read and write that spreadsheet from any chat, with OAuth-secured access to your Quadratic account.

Yes. Once the Sheet is imported into Quadratic, ChatGPT (Plus, Pro, Business, or Enterprise) can read cells, pull named ranges, summarize data, write formulas back to the sheet, and generate charts — all via the Quadratic MCP connector.

No. The common workflow is: export to Quadratic, let AI do the heavy lifting (Python analysis, chart building, forecasting), then re-share back as .xlsx or CSV when a teammate needs to view it in Sheets. You keep Google Sheets as the sharing layer and Quadratic as the AI workspace.

You can, but it requires a Google Cloud project, enabling the Sheets API, provisioning a service account, managing a JSON key, and running a local MCP binary. Quadratic MCP removes all of that. You sign in with OAuth once and every AI client works.

Yes. Quadratic supports hundreds of standard spreadsheet formulas — SUM, VLOOKUP/XLOOKUP, INDEX/MATCH, SUMIFS, IF, and more. GOOGLEFINANCE, IMPORTRANGE, and other Google-specific formulas don’t carry over, but Quadratic has built-in stock data, database connections, and Python that replace them with more power.

Yes — that’s one of the biggest upgrades from Google Sheets. Ask Claude or ChatGPT to run pandas, numpy, scikit-learn, or Plotly over your imported Sheet, and it executes inside Quadratic. Apps Script can’t do this and has no library ecosystem.

Yes. Every AI client authenticates via OAuth 2.0, data stays inside your Quadratic workspace, and you can revoke any connected client at any time from Quadratic settings. Quadratic is SOC 2 compliant with self-hosting available for enterprises.

Gemini inside Google Sheets can help with formulas and light summaries, but it cannot be used from ChatGPT, Claude, Cursor, or any other MCP-compatible AI — and it cannot run Python or SQL on your data. Quadratic MCP opens your spreadsheet to every major AI, with full read/write and native code execution.

Quadratic MCP is included with every Quadratic plan, including the free tier. You only need a Quadratic account and an MCP-compatible AI client.

Today the workflow is import/export rather than real-time sync. For most teams this is a feature, not a bug — AI can be disruptive on a shared production Sheet, so doing the work in Quadratic and pushing a reviewed version back to Sheets is the safer default.

CSV works too. Drop any CSV into Quadratic and the MCP can read and write it the same way. .xlsx is preferred because it preserves multi-tab workbooks and formulas.
