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 Airwallex 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_*******" }

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

The Airwallex MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Airwallex account. It provides structured and secure access to your account profile, balances, currency conversions, beneficiaries, global accounts, and transfers, so your agent can review funds, check account details, explore supported currencies, and track financial activity on your behalf.

  • Account and balance checks: Have your agent review your Airwallex account profile and report available, pending, reserved, prepayment, and total balances by currency.
  • Currency conversion visibility: Let the agent check which currencies you can buy or sell and review recent conversions by currency, status, or date.
  • Beneficiary lookup: Direct your agent to find beneficiaries by identity, bank account details, entity type, or creation date.
  • Global account review: Instruct your agent to list global accounts and narrow them by country, currency, nickname, status, or creation date.
  • Transfer tracking: Have your agent review transfers and filter them by currency, destination, status, or creation date.

Conclusion

You've successfully integrated Airwallex with Codex using Composio's MCP server. Now you can interact with Airwallex 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 Airwallex operations
  • Managed authentication through Composio
  • Access to 20,000+ tools across 1000+ apps for cross-app workflows
  • CodeAct workbench for complex tool chaining

Next steps:

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

FAQ

Frequently asked questions

With a standalone Airwallex MCP server, the agents and LLMs can only access a fixed set of Airwallex tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Airwallex and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Codex fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Airwallex tools.

Yes, absolutely. You can configure which Airwallex scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Airwallex data and credentials are handled as safely as possible.
