## Description

Securely connect your AI agents and chatbots (Claude, ChatGPT, Cursor, etc) with Commerce Layer MCP or direct API to create and manage orders, update inventory levels, adjust prices and promotions, and track fulfillment and shipments through natural language.

## Summary

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.

## Categories

- e-commerce

## Toolkit Details

- Tools: 10

## Images

- Logo: https://logos.composio.dev/api/commerce_layer

## Authentication

- **S2s Oauth2**
  - Type: `custom`
  - Description: S2s Oauth2 authentication for Commerce Layer.
  - Setup:
    - Configure S2s Oauth2 credentials for Commerce Layer.
    - Use the credentials when creating an auth config in Composio.

## Suggested Prompts

- List open orders created in last day
- Create refund for order 12345 now
- Update inventory levels for SKU 5678

## 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. |

## Installation and MCP Setup

### Path 1: SDK Installation

#### Path 1, Step 1: Install Composio

Install the Composio SDK
```python
pip install composio_openai
```

```typescript
npm install @composio/openai
```

#### Path 1, Step 2: Initialize Composio and Create Tool Router Session

Import and initialize Composio client, then create a Tool Router session. Use auth_configs.create() and connected_accounts.link() to configure credentials when linking Commerce Layer accounts.
```python
from openai import OpenAI
from composio import Composio
from composio_openai import OpenAIResponsesProvider

composio = Composio(provider=OpenAIResponsesProvider())
openai = OpenAI()
session = composio.create(user_id='your-user-id')
```

```typescript
import OpenAI from 'openai';
import { Composio } from '@composio/core';
import { OpenAIResponsesProvider } from '@composio/openai';

const composio = new Composio({
  provider: new OpenAIResponsesProvider(),
});
const openai = new OpenAI({});
const session = await composio.create('your-user-id');
```

#### Path 1, Step 3: Execute Commerce Layer Tools via Tool Router with Your Agent

Get tools from Tool Router session and execute Commerce Layer actions with your Agent (use a concrete Commerce Layer prompt below).
```python
tools = session.tools
response = openai.responses.create(
  model='gpt-4.1',
  tools=tools,
  input=[{
    'role': 'user',
    'content': 'List open orders created in the last 24 hours and summarize totals by currency'
  }]
)
result = composio.provider.handle_tool_calls(
  response=response,
  user_id='your-user-id'
)
print(result)
```

```typescript
const tools = session.tools;
const response = await openai.responses.create({
  model: 'gpt-4.1',
  tools: tools,
  input: [{
    role: 'user',
    content: 'List open orders created in the last 24 hours and summarize totals by currency'
  }],
});
const result = await composio.provider.handleToolCalls(
  'your-user-id',
  response.output
);
console.log(result);
```

### Path 2: MCP Server Setup

#### Path 2, Step 1: Install Composio

Install the Composio SDK for Python or TypeScript
```python
pip install composio claude-agent-sdk
```

```typescript
npm install @composio/core ai @ai-sdk/openai @ai-sdk/mcp
```

#### Path 2, Step 2: Initialize Client and Create Tool Router Session

Import and initialize the Composio client, then create a Tool Router session for Commerce Layer. You can call mcp.create() (via composio.create()) to provision the Tool Router session and retrieve session.mcp.url.
```python
from composio import Composio
from claude_agent_sdk import ClaudeSDKClient, ClaudeAgentOptions

composio = Composio(api_key='your-composio-api-key')
session = composio.create(user_id='your-user-id')
url = session.mcp.url
```

```typescript
import { Composio } from '@composio/core';

const composio = new Composio({ apiKey: 'your-api-key' });
const session = await composio.create('your-user-id');
console.log(`Tool Router session created: ${session.mcp.url}`);
```

#### Path 2, Step 3: Connect to AI Agent

Use the MCP server with your AI agent (Anthropic Claude or Mastra)
```python
import asyncio

options = ClaudeAgentOptions(
    permission_mode='bypassPermissions',
    mcp_servers={
        'tool_router': {
            'type': 'http',
            'url': url,
            'headers': {
                'x-api-key': 'your-composio-api-key'
            }
        }
    },
    system_prompt='You are a helpful assistant with access to Commerce Layer tools.',
    max_turns=10
)

async def main():
    async with ClaudeSDKClient(options=options) as client:
        await client.query('YOUR_SPECIFIC_PROMPT_HERE')
        async for message in client.receive_response():
            if hasattr(message, 'content'):
                for block in message.content:
                    if hasattr(block, 'text'):
                        print(block.text)

asyncio.run(main())
```

```typescript
import { openai } from '@ai-sdk/openai';
import { experimental_createMCPClient as createMCPClient } from '@ai-sdk/mcp';
import { generateText } from 'ai';

const client = await createMCPClient({
  transport: {
    type: 'http',
    url: session.mcp.url,
    headers: {
      'x-api-key': 'your-composio-api-key',
    },
  },
});

const tools = await client.tools();
const { text } = await generateText({
  model: openai('gpt-4o'),
  tools,
  messages: [{
    role: 'user',
    content: 'YOUR_SPECIFIC_PROMPT_HERE'
  }],
  maxSteps: 5,
});

console.log(`Agent: ${text}`);
```
