Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@PurchasePlus MCP check on-hand inventory for tomatoes at the main store"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Official Marketboomer plugin and connection package for PurchasePlus AI assistants.
Use it to connect Cursor, Claude, ChatGPT, and other MCP-capable clients to PurchasePlus. With purchaser access, an assistant can browse catalogues and catalogue-line prices, list delivery addresses, look up inventory (stock locations, on-hand, and WAC), list or inspect stocktakes and recipes, draft requisitions, add items to a buy list, export reports, read invoice files, start invoice-from-document upload, and import a priced-catalogue CSV (HTTPS file URL — never paste the file into chat). With supplier access, an assistant can list and inspect connections, catalogues, catalogued products, customer purchase orders, and invoices, and export entitled reports.
Authentication is OAuth only. Sign in with your PurchasePlus account.

Skills ship with the plugin. They tell agents to fetch live how-to documentation from https://learn.purchaseplus.com/. Clients that do not install the plugin should fetch skills on demand via list_plugin_skills. It returns named full texts: purchaseplus (router), purchaseplus-how-to (help centre), purchaseplus-mcp (tool-use), purchaseplus-supplier-mcp (supplier tool-use).
