Overview

AI-generated overview

Lets an assistant read Lightspeed Retail (R-Series) store data and make limited writes such as creating customers and setting stock.

What it does
Connects an MCP client to a hosted Lightspeed Retail (R-Series) store account. Read tools cover account, shops, items, inventory levels, categories, sales, customers, vendors, purchase orders and employees. Write tools create a customer, update an item and set stock levels. Meta tools report usage and manage a paid subscription.
When to use it
Useful when an assistant needs to look up retail store data such as stock, sales or purchase orders, or to make small catalog and customer changes without opening the Lightspeed back office. Suited to store owners or staff who already have a Lightspeed Retail (R-Series) account.
Requirements
Remote hosted endpoint; no local install. Connect over OAuth by signing in to Lightspeed Retail and approving access; no API keys to paste. A subscription covers one store account, and the free tier allows 100 tool calls per month.
Before you install
Write tools create customers, update items and set stock levels, so changes should be confirmed before running. Access is limited to what the signed-in Lightspeed employee may do. Pro is $9/mo or $90/yr via a Stripe Checkout link; cancelling gives no refund for the current period. Store data is sent to the hosted provider.
