Lightspeed Retail (R-Series) MCP by usefulapi

Work with your Lightspeed Retail (R-Series) store from Claude, Cursor, or any MCP client — look up items, stock per shop, sales, customers, vendors, purchase orders and employees; create customers, edit items and set stock levels. Hosted, no local install: connect with your Lightspeed Retail account over OAuth.

Live endpoint: https://lightspeed-r-series.usefulapi.io/mcp · Homepage: https://usefulapi.io/lightspeed-r-series

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://lightspeed-r-series.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http lightspeed-r-series https://lightspeed-r-series.usefulapi.io/mcp, then run /mcp to log in.
• VS Code: Add to VS Code.
• Cursor and other clients: add the URL as a remote MCP server:

{
  "mcpServers": {
    "lightspeed-r-series": {
      "url": "https://lightspeed-r-series.usefulapi.io/mcp"
    }
  }
}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and you sign in with your Lightspeed Retail (R-Series) account.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/lightspeed-r-series/

On first connect you'll be sent to Lightspeed to sign in and approve access; no API keys to paste. The server can do only what the Lightspeed employee who signs in is allowed to do, and you can revoke access any time from your Lightspeed Retail account settings. One subscription covers one store account.
