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 1000+ 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 One drive MCP in Codex

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

http_headers = { "x-consumer-api-key" = "ck_*******" }What is the One drive MCP server, and what's possible with it?
The One drive MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your OneDrive account. It provides structured and secure access to your cloud files and folders, so your agent can perform actions like uploading documents, sharing files, managing storage, and retrieving version histories on your behalf.
- File and folder management: Effortlessly copy, move, or delete files and folders, keeping your OneDrive organized with just a prompt.
- Easy sharing and collaboration: Instantly generate secure sharing links for documents or folders, making collaboration with others seamless.
- File download and preview: Have your agent fetch files or retrieve visual thumbnails for quick previews and streamlined access.
- Access control and permissions review: Check who can view or edit any file or folder, and manage sharing permissions without manual clicks.
- Version tracking and quota monitoring: Retrieve version histories for files and monitor your storage quota to stay on top of changes and space usage.
Conclusion
You've successfully integrated One drive with Codex using Composio's MCP server. Now you can interact with One drive directly from your terminal, VS Code, or the Codex App using natural language commands.
Key benefits of this setup:
