Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With Cloudconvert MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer.

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 870+ 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 Cloudconvert 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.
Verify the connection
Run codex mcp list to confirm Composio appears as a registered MCP server.
Codex 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
What is the Cloudconvert MCP server, and what's possible with it?
The Cloudconvert MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your CloudConvert account. It provides structured and secure access to your file conversion workflows, so your agent can perform actions like converting files, exporting results to cloud storage, managing webhooks, and exploring supported formats on your behalf.
- Seamless file conversion: Ask your agent to convert documents, images, audio, video, spreadsheets, or presentations between hundreds of supported formats automatically.
- Automated export to cloud storage: Direct your agent to export converted files directly into your Google Cloud Storage or Amazon S3 buckets, streamlining storage and distribution.
- Format discovery and optimization: Have the agent list all supported conversion formats, engines, and options, so you can choose the best settings for your needs.
- Webhook management: Let your agent create, list, or delete webhooks to receive real-time notifications about conversion events and automate downstream processes.
- Task tracking and user info: Retrieve detailed task histories, filter by status or date, and confirm the authenticated user’s account details for secure operations.
