How to integrate Skyfire MCP with Codex
Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With Skyfire MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer.
Skyfire is a payment infrastructure that lets AI agents transact and pay for services autonomously. It streamlines payments for AI applications, reducing manual overhead.
Introduction
Also integrate Skyfire with
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 Skyfire 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.
codex mcp login composioVerify the connection
Run codex mcp list to confirm Composio appears as a registered MCP server.
codex mcp listCodex 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
[mcp_servers.composio]
url = "https://connect.composio.dev/mcp"
http_headers = { "x-consumer-api-key" = "ck_*******" }What is the Skyfire MCP server, and what's possible with it?
The Skyfire MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Skyfire account. It provides structured and secure access to your autonomous payment and transaction infrastructure, so your agent can create tokens, pay for services, check balances, audit charges, and discover available AI-powered services on your behalf.
- Autonomous service payments: Let your agent issue payment tokens and seamlessly pay for AI services or digital goods without manual intervention.
- Wallet balance and charge auditing: Have your agent check buyer wallet balances before transactions and audit token charges to track exactly what was spent and when.
- Discovery of AI and digital services: Enable your agent to browse, filter, and retrieve detailed info about available services using tags or seller agents, streamlining selection and integration.
- Token management and automation: Allow your agent to create, manage, and charge Skyfire tokens (KYA, PAY, KYA+PAY), handling sophisticated payment flows programmatically.
- Service details and compliance checks: Instruct your agent to fetch detailed service terms, API specs, and integration URLs—helping ensure compliance and smooth onboarding before making purchases.
Conclusion
You've successfully integrated Skyfire with Codex using Composio's MCP server. Now you can interact with Skyfire 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 Skyfire 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 Skyfire operations
- Explore cross-app workflows by connecting more toolkits
- Build automation scripts that leverage Codex's AI capabilities

Karan skipped his own birthday party to fix our critical issue. It was 10pm and he diverted his Waymo to help us instead. This really sets the bar — it shows the commitment you need when users rely on your software.
A lot of students tell us that the moment their connected tools start talking to each other inside Opennote feels almost magical. The agent just knows them, and it's immensely helped keep new users on the platform.
We chose Composio over Pipedream because it delivered depth where it mattered — niche tools and tricky edge cases other platforms simply ignored. That gave us confidence to scale without compromising.
As a solo builder, shipping fast is life or death. The only way I can outcompete incumbents is by outmanoeuvring them. Getting bogged down managing agent auth would have been a death sentence.
Before Composio, adding tool integrations was slow and resource-intensive. Each one could take weeks of engineering time, and maintaining them meant constantly keeping up with API changes.
With hands-on help from their founder, we integrated Gmail and Google Drive in just 30 minutes. This level of personal support and commitment is exactly what startups should strive for.
