How to integrate Google Sheets MCP with Codex
Connect Codex to Google Sheets MCP. Add a new sheet named 'q3 sales', update all rows where status is 'pending', and more using natural language, with authentication handled for you.

Why use Composio?
Apart from a managed and hosted MCP server, you will get:
- CodeAct: A dedicated workbench that allows GPT to write its code to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
- Large tool responses: Handle them to minimise context rot.
- Dynamic just-in-time access to 20,000 tools across 1500+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need.
How to install Google Sheets MCP in Codex
Run the setup command
Run this command in your terminal to add the Composio MCP server to Codex.
It will initiate the authentication in a browser window, authorize Codex to access your Composio account.
(Optional) Authenticate with OAuth
To authenticate manually, run the login command to open a browser window and authorize Codex to access your Composio account.
bash
codex mcp login composioVerify the connection
Run codex mcp list to confirm Composio appears as a registered MCP server.
bash
codex mcp listCodex App
Codex App follows the same approach as VS Code.
- Click ⚙️ on the bottom left → MCP Servers → + Add servers → Streamable HTTP:
- Fill the header and Key fields with
{ "x-consumer-api-key" = "ck_*******" }. - The Key is the Composio API key, that you can find on dashboard.composio.dev
- Click on Authenticate and authorize Codex to your Composio account and you're all set.
- Restart and verify if it's there in
.codex/config.toml
bash
[mcp_servers.composio]
url = "https://connect.composio.dev/mcp"
http_headers = { "x-consumer-api-key" = "ck_*******" }Try it
Ask Codex for a Google Sheets task. The first time, Composio asks you to connect your Google Sheets account.
For example, ask it to:
- "Add a new sheet named 'Q3 Sales'"
- "Update all rows where status is 'Pending'"
- "Create a pie chart of expenses by category"
What is the Google Sheets MCP server, and what's possible with it?
The Google Sheets MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Google Sheets account. It provides structured and secure access to your spreadsheets, worksheet data, formatting rules, and charts, so your agent can create, read, update, organize, and export spreadsheet content on your behalf.
- Spreadsheet and worksheet creation: Have your agent create new spreadsheets, add worksheet tabs, copy sheets between spreadsheets, and rename or reorder tabs.
- Data reading and updates: Let the agent retrieve cell ranges, append new records, update values in batches, clear ranges, and upsert rows using a key.
- Data organization: Direct your agent to insert or delete rows and columns, sort ranges, apply filters, resize or hide dimensions, and find and replace text.
- Rules and visual presentation: Instruct your agent to add dropdowns and other data validation rules, manage conditional formatting, and list, move, or resize charts.
- Search and export: Have your agent find spreadsheets, inspect file details, export entire spreadsheets in supported formats, or export a worksheet or selected range as a PDF.
Conclusion
You've successfully integrated Google Sheets with Codex using Composio's MCP server. Now you can interact with Google Sheets directly from your terminal, VS Code, or the Codex App using natural language commands.
Key benefits of this setup:
- Seamless integration across CLI, VS Code, and standalone app
- Natural language commands for Google Sheets operations
- Managed authentication through Composio
- Access to 20,000+ tools across 1500+ apps for cross-app workflows
- CodeAct workbench for complex tool chaining
Next steps:
- Try asking Codex to perform various Google Sheets operations
- Explore cross-app workflows by connecting more toolkits
- Build automation scripts that leverage Codex's AI capabilities

FAQ
Frequently asked questions
With a standalone Google Sheets MCP server, the agents and LLMs can only access a fixed set of Google Sheets tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Google Sheets and many other apps based on the task at hand, all through a single MCP endpoint.
Yes, you can. Codex fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Google Sheets tools.
Yes, absolutely. You can configure which Google Sheets scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.
All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Google Sheets data and credentials are handled as safely as possible.
