Install Spree Commerce: open-source B2B and marketplace ecommerce in Zed

What you need first

• Zed, installed.
• Nothing else: the server runs on its publisher's machines and Zed connects to it.

Steps

1. Open Zed's settings file, ~/.config/zed/settings.json (on Windows %APPDATA%\Zed\settings.json), or .zed/settings.json for one project.
2. Add this block. If the file already has context_servers, add only the entry inside it.

{
  "context_servers": {
    "ecommerce-b2b-marketplace": {
      "url": "https://{store_domain}/api/v3/admin/mcp"
    }
  }
}

3. Save the file. Zed starts the server, and Settings › AI › MCP Servers lists it.

Check it worked

Ask Zed: List the tools of ecommerce-b2b-marketplace.

If it does not start

401 Unauthorized

The endpoint wants a sign-in or a key. Sign in when Zed asks.

Nothing changes after a restart

The file is not valid JSON any more. Look for a missing comma where the block was added.
