How to integrate Cults MCP with Codex
Connect Codex to Cults MCP. List your latest uploaded 3d models, share a new 3d file creation link, and more using natural language, with authentication handled for you.
Api Key
Cults is a digital marketplace for 3D printing models, connecting designers and makers. It lets creators share, sell, and discover a huge variety of printable designs easily.

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 Cults 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.
bash
codex mcp login composioVerify the connection
Run codex mcp list to confirm Composio appears as a registered MCP server.
bash
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
bash
[mcp_servers.composio]
url = "https://connect.composio.dev/mcp"
http_headers = { "x-consumer-api-key" = "ck_*******" }What is the Cults MCP server, and what's possible with it?
The Cults MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Cults account. It provides structured and secure access to your Cults digital marketplace, so your agent can perform actions like sharing new 3D creations, executing advanced queries, and managing approved sharing origins for your designs.
- Fetch approved sharing origins: Instantly retrieve the list of domains authorized to share your 3D models, making it easy to manage and validate sharing destinations.
- Automate GraphQL queries and mutations: Use your agent to run powerful GraphQL operations against the Cults API for custom data retrieval or updates—perfect for creators who need flexibility.
- One-click sharing of new creations (FR): Quickly generate pre-filled links to share your latest 3D files on Cults (in French locale), streamlining the publishing workflow for designers.
- Manage digital assets programmatically: Enable your agent to interact with your Cults account to organize, update, or extend your digital portfolio through the available tools.
Conclusion
You've successfully integrated Cults with Codex using Composio's MCP server. Now you can interact with Cults 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 Cults 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 Cults 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 Cults MCP server, the agents and LLMs can only access a fixed set of Cults tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Cults 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 Cults tools.
Yes, absolutely. You can configure which Cults 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 Cults data and credentials are handled as safely as possible.
