Commerce Layer is a headless commerce platform with transactional APIs for orders, inventory, pricing, customers, and fulfillment. Use it to centralize ecommerce operations and surface real-time commerce data.

10 Tools

Introduction

Hermes is a 24/7 autonomous agent that lives on your computer or server — it remembers what it learns and evolves as your usage grows.

This guide explains the easiest and most robust way to connect your Commerce Layer account to Hermes. You can do this through either Composio Connect CLI or Composio Connect MCP. For personal use we recommend the CLI, but you won't go wrong with MCP either.

What is Composio Connect?

Composio Connect is a consumer offering that lets anyone plug 1,500+ applications directly into their agent harness — including Hermes. It can:

  • Search and load tools from relevant toolkits on-demand, reducing context usage.
  • Chain multiple tools to accomplish complex workflows via a remote workbench, without excessive back-and-forth with the LLM.
  • Manage app authentication end-to-end with zero manual overhead.

Integrating Commerce Layer with Hermes

Using Composio Connect CLI

1. Install the Composio CLI

Run the install script directly, or paste https://composio.dev/hermes into your Hermes chat box to have it installed for you.

bash
curl -fsSL https://composio.dev/install | bash
Hermes authenticating with Composio

2. Authenticate

Once the CLI is installed, ask Hermes to authenticate with Composio.

3. Connect to Commerce Layer

Ask your agent to connect to Commerce Layer, or simply request any Commerce Layer-related task. Hermes will prompt you to authenticate and authorize access.

4. Done. You're all set with a new Commerce Layer connection.

Using Composio Connect MCP

1. Get your MCP URL and API Key

Go to dashboard.composio.dev and copy your Connect MCP URL and API key.

2. Open the Hermes config file

bash
nano ~/.hermes/config.yaml

3. Add the Composio Connect MCP server

bash
mcp_servers:
  composio:
    url: "https://connect.composio.dev/mcp"
    headers:
      x-consumer-api-key: "YOUR_COMPOSIO_API_KEY"
    connect_timeout: 60
    timeout: 180

Save with Ctrl + O, Enter, then exit with Ctrl + X.

4. Restart your Hermes agent

Once restarted, ask your agent to connect to Commerce Layer or request any Commerce Layer-related task. It will prompt you to authenticate and authorize access.

5. Done!

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

The Commerce Layer MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Commerce Layer account. It provides structured and secure access to your customers, orders, catalog, inventory, and order analytics, so your agent can manage customers, review orders, calculate order metrics, browse SKUs, and check stock levels on your behalf.

  • Customer management: Have your agent create customers, find their account details, update selected information, or permanently remove customer records.
  • Order review: Let the agent list recent orders and retrieve individual orders with related customer, line item, shipment, or return details.
  • Order performance metrics: Direct your agent to calculate common order KPIs filtered by date, market, currency, or order status.
  • Catalog discovery: Instruct your agent to browse SKUs and find the products available in your Commerce Layer catalog.
  • Inventory checks: Have your agent review stock items, available quantities, and related SKU codes to answer inventory questions.

Way Forward

With Commerce Layer connected, Hermes can now act on your behalf whenever it detects a relevant task or you ask it to.

From here, you can extend Hermes further:

  • Connect more apps: Calendar, Slack, Notion, Linear, and hundreds of others are available through the same Composio Connect setup. Each new integration compounds what Hermes can do for you.
  • Build workflows across tools: Once multiple apps are connected, Hermes can chain actions together — turn an email into a calendar invite, a Slack message into a Linear ticket, or a meeting note into a follow-up draft.
  • Let it learn your patterns: The more you use Hermes, the better it gets at anticipating how you'd handle recurring tasks. Give it feedback on drafts and decisions, and it will adapt.

FAQ

Frequently asked questions

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

Yes, you can. Hermes 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 Commerce Layer tools.

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