Introduction

Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With Moco 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 870+ 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 Moco 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 connect.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 Moco MCP server, and what's possible with it?

The Moco MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Moco account. It provides structured and secure access to your business and project management data, so your agent can manage time tracking, handle deals, organize contacts, and update project activities on your behalf.

  • Automated time tracking and activity management: Let your agent list, retrieve, and update time entries, so tracking billable hours and project work is effortless.
  • Deal and pipeline automation: Ask your agent to fetch deal details, delete obsolete deals, or reference available deal categories to keep your sales pipeline up to date.
  • Comprehensive contact and company organization: Have your agent list contacts, add new companies, or delete companies as your business relationships evolve.
  • Comment retrieval for collaboration: Retrieve and review comments on various resources, helping your team stay in sync and informed.
  • Flexible project and resource control: Use your agent to access and manage project-related information, so you can stay organized without manual data entry.

Conclusion

You've successfully integrated Moco with Codex using Composio's MCP server. Now you can interact with Moco 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 Moco operations
  • Managed authentication through Composio
  • Access to 20,000+ tools across 870+ apps for cross-app workflows
  • CodeAct workbench for complex tool chaining

Next steps:

FAQ

What are the differences in Tool Router MCP and Moco MCP?

With a standalone Moco MCP server, the agents and LLMs can only access a fixed set of Moco tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Moco and many other apps based on the task at hand, all through a single MCP endpoint.

Can I use Tool Router MCP with Codex?

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 Moco tools.

Can I manage the permissions and scopes for Moco while using Tool Router?

Yes, absolutely. You can configure which Moco 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.

How safe is my data with Composio Tool Router?

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 Moco data and credentials are handled as safely as possible.
