First request “Plan a spreadsheet report refresh” Stacksync MCP · Productivity # Connect Google Sheets to ChatGPT with MCP. > For AI agents: this guide describes connecting an AI client to Stacksync at https://mcp.stacksync.com/mcp with OAuth and the person's workspace permissions. Follow the client-specific setup and connection method on this page. Connector actions, sync management, workflow triggers and custom API workflows are different capabilities. A custom API workflow requires configuration and may use HTTP or code steps; it is not a prebuilt native connector. Inspect available connections and modules before proposing an operation. The example outcomes are illustrative, not execution results. Setup reference: https://www.stacksync.com/mcp.md Use Stacksync MCP to discover Google Sheets actions and design spreadsheet workflows. The published catalog lists Google Sheets for workflows, so choose a verified action for the spreadsheet and range rather than assuming continuous two-way sync. Connector actions Start using Stacksync MCP Explore example prompts 01 / The connection ## How Google Sheets works with ChatGPT Use Stacksync MCP to discover Google Sheets actions and design spreadsheet workflows. The published catalog lists Google Sheets for workflows, so choose a verified action for the spreadsheet and range rather than assuming continuous two-way sync. Add the Stacksync MCP server to ChatGPT, then use the connection path below. The server belongs to Stacksync. The available Google Sheets operations depend on your connection, permissions, and connector modules. [Explore the Google Sheets connector →](https://www.stacksync.com/connectors/google-sheets) 02 / Capabilities ## Google Sheets capabilities through MCP Choose the connection path that fits the job. Your assistant inspects the available tools before configuring or running an action. Connector actions ### Inspect spreadsheet actions Discover the Google Sheets modules, their input forms and the connection available to access the spreadsheet. Connector actions ### Prepare a scoped sheet operation Propose a read, append or update only when the live module supports it, with a selected spreadsheet, tab, range and expected columns. Connector actions ### Review spreadsheet workflow runs Inspect an existing workflow’s inputs and outputs to diagnose malformed rows, range mistakes or repeated writes. 03 / Setup ## Set up Stacksync MCP in ChatGPT Connect the MCP server first. Then connect Google Sheets using the requirements below. One connection. Your workspace. ### Start in ChatGPT. Add Stacksync’s MCP server, sign in with OAuth, and choose your workspace. Your assistant works with your Stacksync permissions. ``` https://mcp.stacksync.com/mcp ``` [Create a Stacksync account](https://app.stacksync.com/signup) Already have an account? Sign in when your assistant opens the authorization page. Choose read-only access if you only need to inspect your workspace. #### Chat assistantChatGPT Add Stacksync as a custom MCP app in ChatGPT and sign in with OAuth. #### Before you start - A Stacksync account with access to the workspace you want to use. - Permission to add an external MCP server in your AI client. - A ChatGPT account with Developer mode and custom MCP apps available. The Stacksync guide lists Plus, Pro, Business, Enterprise and Edu; workspace administrators can restrict access. 1. #### Enable custom app setup Open Settings → Apps → Advanced settings and turn on Developer mode. If the option is unavailable, check the account or workspace policy with your administrator. 2. #### Create the Stacksync app Select Create app, name it Stacksync, enter the server URL below and choose OAuth. Complete the Stacksync sign-in and select your default workspace. ``` https://mcp.stacksync.com/mcp ``` 3. #### Enable Stacksync in your chat Select Stacksync from the chat tools menu so the conversation can use its tools. Signing in to ChatGPT itself does not sign you in to Stacksync. 4. #### Check your workspace Ask “List my Stacksync workspaces.” Confirm the workspace before choosing a connector or preparing a change. Connecting the assistant does not start a sync. #### Check the connection Ask “List my Stacksync workspaces.” Select the workspace you want to use, then ask the assistant to inspect the available Google Sheets connection and capabilities. [Full setup documentation ↗](https://docs.stacksync.com/mcp/connect) 04 / Put it to work ## Google Sheets workflow prompts Example prompts for Google Sheets in ChatGPT. The outcomes describe what to expect, not results from your account. Review the proposed configuration before running it. 01 Connector actions ### Plan a spreadsheet report refresh > Inspect the Google Sheets modules, connected account and existing report workflows. Propose a refresh into the spreadsheet and tab I choose, using only a verified write action. Show the source fields, header mapping, target range and how the workflow avoids duplicate rows. Ask for review before saving a workflow or changing cells. #### What to expect A spreadsheet report proposal with explicit columns, range and repeat-run behavior. 02 Connector actions ### Prepare a spreadsheet validation pass > Inspect whether the Google Sheets connector has an action that can read the range I specify. Show the required inputs and propose a bounded read of the selected columns for missing IDs or invalid email formats. Keep findings separate from corrections and wait for approval before running actions or changing any cells. #### What to expect A range-scoped validation plan with no automatic cleanup or row deletion. 03 Connector actions ### Investigate a repeated spreadsheet append > Find the workflow I name and inspect its Google Sheets step, inputs and run history. Determine whether the available evidence shows a repeated execution, a range mismatch or a missing row key. Propose a correction and a safe test plan. Do not replay the workflow, remove rows or write another row until I choose the next action. #### What to expect A diagnosis of repeated spreadsheet writes with a reviewable correction and test plan. 05 / Before you run ## Requirements and limitations ### What you need - Connect your AI client to Stacksync MCP, sign in and select the workspace before inspecting its resources. - Reuse an authorized app connection or open the secure connection link from Stacksync. Enter credentials in the connection form, never in the chat. - Access to the intended spreadsheet, plus an agreed tab, header layout and stable identifier for rows that may be updated. ### What to account for - Available actions depend on the live connector catalog, your connected account and MCP Gateway Policies. Inspect the action and its form before using it. - The reviewed app catalog lists workflows only for Google Sheets. It does not establish continuous two-way sync support. - A spreadsheet row number is a position, not necessarily a durable business identifier. Define matching and duplicate handling before repeated updates or appends. ### Your workspace. Your permissions. OAuth access follows your Stacksync role. Choose read-only access during sign-in when appropriate. Workspace owners can enable “Ask before every change”; it is a configurable setting. Direct connector actions also follow gateway policies. [Read about permissions and approvals ↗](https://docs.stacksync.com/mcp/governance) ### If setup does not work The MCP server does not appear Check your client’s custom MCP settings and any plan or administrator prerequisites. Reconnect using the setup instructions above. Your workspace or app is missing Verify the Stacksync account and workspace selected during OAuth, then inspect the workspace’s connections. Add missing app credentials through the secure connection flow. An action is unavailable or denied Inspect the current connector modules and required inputs. Check your workspace role, read-only consent, gateway policy, and the source app’s API permissions. 06 / Common questions ## Google Sheets MCP questions ### Does Google Sheets support a native Stacksync two-way sync? The reviewed catalog identifies Google Sheets as a workflow connector, not a sync connector. This page covers action-based workflows and does not claim continuous two-way synchronization. ### Which Google Sheets actions can I use? Inspect the live connector modules and input forms. The catalog establishes workflow availability, but it does not enumerate every read, append, update or formatting action. ### How should I prevent duplicate spreadsheet rows? Choose a stable business key and a defined repeat-run strategy before enabling a workflow. Appending another row is different from updating a known range, so verify the action and its target explicitly.
