# Shopping Agent with MCP

The MCP lets your agent shop. It's the fastest way to explore what’s possible with Channel3. You can use it without writing any code, and without an API key.

## 1. Connect MCP

Point your agent at:

```text theme={"theme":{"light":"github-light","dark":"github-dark"}}
https://mcp.trychannel3.com/
```

## 2. Run a prompt

```text theme={"theme":{"light":"github-light","dark":"github-dark"}}
Search for merino wool sweaters under $150 that are in stock.
```

```text theme={"theme":{"light":"github-light","dark":"github-dark"}}
Look up this product URL and show every store selling it with price and availability:
https://www.nike.com/t/air-force-1-07-mens-shoes-5QFp5Z/CW2288-111
```

Your agent selects Channel3 tools automatically. See [available tools](/mcp/tools) and [usage examples](/mcp/usage) for more.

## 3. Add an API key for production

For unlimited usage and to earn commissions on sales, add an API key.

1. [Create an account](https://trychannel3.com/sign-up/developer)
2. Copy your key
3. Send it with every request as a header:

```text theme={"theme":{"light":"github-light","dark":"github-dark"}}
X-API-Key: <your-api-key>
```

To call it from your own agent, point any MCP client library at the same URL and send the key as an `X-API-Key` header.
