How to integrate ImageRouter MCP with Codex

Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With ImageRouter 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 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 ImageRouter 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 ImageRouter MCP server, and what's possible with it?

The ImageRouter MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your ImageRouter account. It provides structured and secure access to ImageRouter's generative models, model details, and account credits, so your agent can generate images, edit images, create videos, produce text, and review usage on your behalf.

  • Image generation: Have your agent turn a detailed text prompt into an image using a selected ImageRouter model.
  • Image editing: Direct your agent to transform or inpaint one or more existing images provided as web links or embedded image data.
  • Video creation: Let the agent generate videos from written prompts, with optional images supplied as visual inputs.
  • Text and multimodal responses: Instruct your agent to create text completions or responses based on plain text and structured multimodal input.
  • Model and credit checks: Have your agent discover available models, review their capabilities, supported options, and pricing, then check remaining credits and usage before starting paid work.

Conclusion

You've successfully integrated ImageRouter with Codex using Composio's MCP server. Now you can interact with ImageRouter 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 ImageRouter 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 ImageRouter 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 ImageRouter MCP server, the agents and LLMs can only access a fixed set of ImageRouter tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from ImageRouter 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 ImageRouter tools.

Yes, absolutely. You can configure which ImageRouter 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 ImageRouter data and credentials are handled as safely as possible.
