Introduction

Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With the Google Slides MCP integration, Codex can create presentations, build slides from Markdown, copy decks from templates, update slide content, and fetch page thumbnails, all without leaving the terminal or the app, whichever you prefer.

For exact tool slugs and parameter tables, see the tool catalog in the Composio docs.

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 1700+ 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 Slides MCP in Codex

Run the setup command

Run this command in your terminal to add the Composio MCP server to Codex.

Terminal

It will initiate the authentication in a browser window, authorize Codex to access your Composio account.

Composio authentication page

(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 composio

Verify the connection

Run codex mcp list to confirm Composio appears as a registered MCP server.

bash
codex mcp list

Codex App

Codex App follows the same approach as VS Code.

  1. Click ⚙️ on the bottom left → MCP Servers → + Add servers → Streamable HTTP:
  2. Fill the header and Key fields with { "x-consumer-api-key" = "ck_*******" }.
  3. The Key is the Composio API key, that you can find on dashboard.composio.dev
  4. Click on Authenticate and authorize Codex to your Composio account and you're all set.
Codex App MCP setup
  1. 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 Slides task. The first time, Composio asks you to connect your Google Slides account.

For example, ask it to:

  • "Turn this meeting summary into slides"
  • "Add a new slide with project milestones"
  • "Update presentation with these markdown notes"

What is the Google Slides MCP server, and what's possible with it?

The Google Slides 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 Slides account. It provides structured and secure access to your presentations, so your agent can create slides from markdown, update existing decks, fetch presentation details, and generate slide previews on your behalf.

  • Create presentations and slides automatically: Let your agent generate brand new Google Slides decks or add slides using markdown or templates for fast, professional results.
  • Bulk update presentations with markdown: Effortlessly refresh or enhance existing decks by sending markdown content or batch updates, applying themes, smart formatting, and more.
  • Fetch and inspect presentation details: Retrieve up-to-date information for entire presentations or specific slides, layouts, and notes to keep track of content and structure.
  • Generate slide thumbnails for previews: Instantly produce thumbnail images of any slide page, making it easy to review or share snapshots of your presentations.
  • Duplicate and initialize presentations: Quickly create blank presentations or duplicate existing ones to streamline your workflow and maintain consistency across projects.

Conclusion

You've successfully integrated Google Slides with Codex using Composio's MCP server. Now you can interact with Google Slides 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 Slides operations
  • Managed authentication through Composio
  • Access to 20,000+ tools across 1700+ apps for cross-app workflows
  • CodeAct workbench for complex tool chaining

Next steps:

  • Try asking Codex to perform various Google Slides operations
  • Explore cross-app workflows by connecting more toolkits
  • Build automation scripts that leverage Codex's AI capabilities
