Introduction

Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With Zep 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 Zep 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.

(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.

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 Zep MCP server, and what's possible with it?

The Zep MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Zep account. It provides structured and secure access so your agent can perform Zep operations on your behalf.

Conclusion

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

FAQ

Frequently asked questions

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

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