Introduction

Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With the Api labz MCP integration, Codex can validate IBANs, list your Airtable tables, run AI searches across Trello, and sync deals, 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 Api labz 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 Api labz task. The first time, Composio asks you to connect your Api labz account.

For example, ask it to:

  • "Validate this IBAN before making payment"
  • "Add a new deal record to CRM"
  • "List all Airtable tables in your project base"

What is the Api labz MCP server, and what's possible with it?

The API Labz MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your API Labz account. It provides structured and secure access to IBAN validation, deal integration, Airtable table listings, and Trello card search, so your agent can validate bank account numbers, integrate deals, list Airtable tables, and find relevant Trello cards on your behalf.

  • IBAN validation: Have your agent validate International Bank Account Numbers before using them in financial workflows.
  • Deal integration: Direct your agent to add deals to API Labz as part of your sales workflow.
  • Airtable table discovery: Let the agent list the tables available in a chosen Airtable base.
  • Trello card search: Instruct your agent to use semantic search to find relevant Trello cards across boards and lists.

Conclusion

You've successfully integrated Api labz with Codex using Composio's MCP server. Now you can interact with Api labz 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 Api labz 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 Api labz operations
  • Explore cross-app workflows by connecting more toolkits
  • Build automation scripts that leverage Codex's AI capabilities
