Introduction

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

Also integrate Baselinker with

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

The Baselinker MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Baselinker account. It provides structured and secure access to your e-commerce data, so your agent can perform tasks like managing orders, tracking inventory, processing receipts, and retrieving sales information on your behalf.

  • Order management and retrieval: Let your agent fetch, filter, and download order details—including by date, status, or customer email—for fast access to sales and customer data.
  • Inventory and purchase order tracking: Automatically retrieve current inventory documents, view purchase orders, and get document series to keep your stock and supply chain in check.
  • External storage and warehouse discovery: Seamlessly list all external stores and warehouses connected to your Baselinker account, so your agent knows where your products live.
  • Order status and custom field mapping: Ask your agent to pull order statuses or extra field definitions, making it easy to interpret, categorize, and automate order processing flows.
  • Pending receipt management: Quickly fetch receipts that still need to be issued, helping your team stay on top of fiscal compliance and transaction documentation.

FAQ

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

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

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

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