Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With Kraken io 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 Kraken io 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 Kraken io MCP server, and what's possible with it?
The Kraken io MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Kraken io account. It provides structured and secure access to your image optimization tools, so your agent can automatically compress images, resize or convert files, monitor account usage, and test optimizations without consuming real credits.
- Real-time image optimization by URL: Instantly compress, resize, or convert images hosted on public URLs—perfect for streamlining website performance or social media workflows.
- Quota and account status monitoring: Let your agent check your Kraken.io plan limits, remaining quota, and current account status before processing images, so you never hit a surprise limit.
- Metadata preservation during compression: Instruct your agent to optimize images while keeping essential EXIF and metadata intact, making sure important information stays with your files.
- Sandbox image upload and testing: Safely upload and optimize images in sandbox mode, allowing you to test settings and workflows without using up your actual credits.
