Connect via MCP (Beta)

This feature is in beta. Turn it on under Settings → Experimental in Nifty. Changes made by an assistant apply immediately and can't be undone. Only connect assistants you trust, and use at your own risk.

Connect Nifty to ChatGPT, Claude, Gemini, or any other MCP-compatible assistant, then ask about your inventory, orders, and sales in plain English.

Choose your assistant

• Claude — add Nifty from the Claude connector directory. It always has the latest tools.

• ChatGPT — add Nifty as a custom connection. The Nifty plugin in the ChatGPT directory is under review and doesn't have the latest tools yet.

• Gemini — add Nifty as a custom app and use it in Gemini Spark. Requires a Google AI Pro or Ultra subscription.

• Any other MCP client — add this server URL with OAuth authentication:

https://api.nifty.ai/api/mcp

What you can ask

• "How many items do I have listed on Poshmark?"

• "Show me my sales for the last 30 days."

• "What's my profit and loss for May?"

• "Itemize the expenses I entered in Analytics for May.

• "Compare the sell-through rate of my items labeled 'Consignment' vs 'Goodwill'."

• "Lower the eBay price of my Patagonia fleece to $40."

What the assistant can change

• Favorite or unfavorite items.

• Save or update private notes on items.

• Create, update, and delete labels.

• Add labels to items or remove them.

• Edit item titles, descriptions, conditions, quantities, costs, SKUs, listing prices, and each marketplace's category and attributes. Edits to listed items are republished to the marketplaces, usually within 10–15 seconds and rarely up to a minute.

These are the only changes the assistant can make. It cannot create or delete items, change your account settings, or manage your marketplace connections.

• On Claude Team/Enterprise and ChatGPT Business/Enterprise/Edu plans, a workspace admin must enable the Nifty connector (or allow custom connectors) before members can use it.

Troubleshooting

Missing a tool, or a tool that fails with "Tool not found"? New tools are released regularly, and assistants keep the tool list from when you connected. Make sure MCP server access is turned on under Settings → Experimental in Nifty, then follow the troubleshooting steps for Claude, ChatGPT, or Gemini.
