## Introduction

Atomic Agent is an open-source AI agent that runs on your machine and supports local models through llama.cpp. Connect it to 1,500+ apps through Composio, including Commerce Layer.
This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Commerce Layer account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions.

## TL;DR

### How Atomic Agent connects to Commerce Layer
Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication.
Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account.

## Connect Commerce Layer to Atomic Agent

### Connect Commerce Layer to Atomic Agent
- Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key.
- In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart.
- Ask Atomic Agent to do something in Commerce Layer. It searches Composio for the right tool.
- On first use, open the sign-in link returned in the chat. Connect your Commerce Layer account, then return to Atomic Agent to continue.
### Headless setup
Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file.

```bash
COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY
```

## 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 so your agent can perform Commerce Layer operations on your behalf.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `COMMERCE_LAYER_CREATE_CUSTOMER` | Create Customer | Create one Commerce Layer customer from an email and optional external-reference metadata. Use a unique email or reference for automation. This mutation is cleanly undoable with DELETE_CUSTOMER using the returned customer ID. |
| `COMMERCE_LAYER_DELETE_CUSTOMER` | Delete Customer | Permanently delete one Commerce Layer customer by exact ID. This irreversible operation requires explicit confirmation and is intended only for confirmed cleanup or erasure, never bulk deletion. Never infer or enumerate customer IDs; call GET_CUSTOMER first unless deleting a fixture created in the same workflow. |
| `COMMERCE_LAYER_GET_CUSTOMER` | Get Customer | Retrieve one customer by its Commerce Layer resource ID. |
| `COMMERCE_LAYER_GET_ORDER` | Get Order | Retrieve one Commerce Layer order by ID, optionally including customer, line-item, shipment, or return context. |
| `COMMERCE_LAYER_GET_ORDER_METRIC` | Get Order Metric | Compute one common order KPI over optional date, market, currency, and status filters using the Commerce Layer Metrics API. |
| `COMMERCE_LAYER_LIST_CUSTOMERS` | List Customers | Return one page of customers, optionally filtered by an exact email address. |
| `COMMERCE_LAYER_LIST_ORDERS` | List Orders | Return one page of orders, newest first by default, for operational review and follow-up by order ID. |
| `COMMERCE_LAYER_LIST_SKUS` | List SKUs | Return one page of catalog SKUs for product discovery and ID lookup. |
| `COMMERCE_LAYER_LIST_STOCK_ITEMS` | List Stock Items | Return one page of stock items with inventory quantities and SKU codes. |
| `COMMERCE_LAYER_UPDATE_CUSTOMER` | Update Customer | Update selected attributes of one Commerce Layer customer. Only non-null fields supplied by the caller are changed. Inspect the customer first when rollback matters; restoring the captured values reverses this update. |

## Troubleshooting

### Why is my API key rejected?

Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying.

### Why are Composio tools unavailable after saving a key?

Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk.

### Does Composio have a free plan?

The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See [Composio pricing](/pricing) for the current limits that apply to your connection.

## Conclusion

### Use Commerce Layer from Atomic Agent
With your account connected, ask Atomic Agent to work with Commerce Layer in natural language. You can connect more apps through the same Composio integration as you need them.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Commerce Layer MCP?

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.

### Can I use Tool Router MCP with Atomic Agent?

Yes, you can. Atomic Agent 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.

### Can I manage the permissions and scopes for Commerce Layer while using Tool Router?

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.

### 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 Commerce Layer data and credentials are handled as safely as possible.
