How to integrate Eden AI MCP with Codex

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

The Eden AI MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Eden AI account. It provides structured and secure access to your AI models, generated responses, safety checks, model catalog, and usage data, so your agent can generate text, create embeddings, moderate content, discover model capabilities, and track costs on your behalf.

  • Text generation and response retrieval: Have your agent generate text with supported models, continue saved responses, and retrieve earlier results for follow-up work.
  • Embeddings for search and analysis: Direct your agent to turn individual texts or batches into embeddings for semantic search, clustering, and similarity tasks.
  • Content safety checks: Let the agent moderate one or more texts, identify flagged safety categories, and review confidence scores before using the content.
  • Model and capability discovery: Instruct your agent to find available models and compare supported features, providers, pricing, and regions before choosing one.
  • Usage planning and cost tracking: Have your agent count tokens before generating content, check account credits, and review consumption by provider or feature over a selected period.

Conclusion

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

Supported Tools

Every Eden AI action and event your agent gets out of the box.

Count Anthropic Tokens

Count input tokens for an Anthropic-format message request before generation, including system content and tool definitions.

Create Anthropic Message

Generate a non-streaming Anthropic-compatible message with content blocks, stop reason, token usage, provider metadata, and Eden AI cost.

Create Chat Completion

Generate a non-streaming OpenAI-compatible chat completion with a current Eden AI model and return its choices, token usage, provider, and cost.

Create Embeddings

Create embeddings for one text or a batch of texts and return vectors with model, usage, provider, and cost metadata.

Create Response

Create or continue a synchronous OpenAI Responses-compatible text response, stored by default for later retrieval, and return its ID, structured output, text, usage, provider, and cost.

Discover AI Capabilities

Find current Eden AI models or inspect Universal AI feature schemas, providers, pricing, and regions before an execution call.

Get Cost Overview

Return current account credits and, when a date range is supplied, aggregated consumption filtered by provider or subfeature.

Get Response

Retrieve a previously stored Responses API object by ID, including its status, text output, structured output, usage, and canonical model.

Moderate Text

Classify one text or a batch of texts for safety categories and return flags, category scores, applied input types, provider, and cost.

Run Universal AI

Run one synchronous Eden AI Universal AI feature using a current model and feature-specific input.

FAQ

Frequently asked questions

With a standalone Eden AI MCP server, the agents and LLMs can only access a fixed set of Eden AI tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Eden AI 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 Eden AI tools.

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