Shows Shopify store owners what to reorder, how much to buy and which stock is running low or sitting idle.
Connects to a Shopify store through Forthcast to show live stock, demand forecasts, reorder points, suggested order quantities, open purchase orders and supplier performance. Standalone calculators for safety stock, order quantity and demand forecasting work without a connected store. Read-only: it does not create or change purchase orders.
Try asking Muse: "Which of my Shopify products are at risk of running out in the next two weeks, and how many should I reorder from each supplier?"

Forthcast Inventory is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
In Claude, open Settings, then Connectors.
Choose Add custom connector, give it a name, and paste the link.
If it needs a sign-in, Claude sends you to it. Then turn the connector on in a chat from the tools menu and ask.
Custom connectors are available on paid Claude plans; on Team and Enterprise accounts an admin may need to add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in Claude
