Introduction

Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With Asana MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or app, whichever you prefer.

Composio removes the Authentication handling completely from you. We handle the entire integration lifecycle, and all you need to do is just copy the URL below, authenticate inside Codex, and start using it.

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 Asana MCP in Codex

Codex CLI

Run the command in your terminal.

Terminal

This will auto-redirect you to the Rube authentication page.

Rube authentication redirect page

Once you're authenticated, you will be able to access the tools.

Verify the installation by running:

codex mcp list

If you otherwise prefer to use config.toml, add the following URL to it. You can get the bearer token from rube.app → Use Rube → MCP URL → Generate token

[projects."/home/user/composio"]
trust_level = "untrusted"

[mcp_servers.rube]
bearer_token_env_var = "your bearer token"
enabled = true
url = "https://rube.app/mcp"

Codex in VS Code

If you have installed Codex in VS Code.

Then: ⚙️ → MCP Settings → + Add servers → Streamable HTTP:

Add the Rube MCP URL: https://rube.app/mcp and the bearer token.

VS Code MCP Settings

To verify, click on the Open config.toml

Open config toml in Codex

Make sure it's there:

[mcp_servers.composio_rube]
bearer_token_env_var = "your bearer token"
enabled = true
url = "https://rube.app/mcp"

Codex App

Codex App follows the same approach as VS Code.

  1. Click ⚙️ on the bottom left → MCP Servers → + Add servers → Streamable HTTP:
Codex App MCP Settings
  1. Restart and verify if it's there in .codex/config.toml
[mcp_servers.composio_rube]
bearer_token_env_var = "your bearer token"
enabled = true
url = "https://rube.app/mcp"
  1. Save, restart the extension, and start working.

What is the Asana MCP server, and what's possible with it?

The Asana MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Asana account. It provides structured and secure access to your Asana workspace, so your agent can perform actions like creating tasks, managing projects, tagging work, assigning followers, and attaching files on your behalf.

  • Automated task creation and updates: Let your agent create new tasks with specific details, add tasks to projects or sections, and update them as work progresses.
  • Collaborator and follower management: Easily add users as followers to tasks, ensuring that the right people stay informed and engaged with project updates.
  • Project and workspace organization: Create new projects, define custom fields, and set up tags to keep your Asana workspace organized and tailored to your team's workflow.
  • File and attachment handling: Allow your agent to upload and attach important files directly to tasks, making sure all documentation stays in the right context.
  • Goal and resource linking: Link tasks, projects, or portfolios to goals, or add supporting relationships to help your team track progress and dependencies more effectively.

FAQ

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

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

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

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