It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

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
https://lightspeed-r-series.usefulapi.io/mcp.claude mcp add --transport http lightspeed-r-series https://lightspeed-r-series.usefulapi.io/mcp, then run /mcp to log in.{
"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.
