Universal wishlist for AI shopping experiences. Save any product URL from any store to a wishlist. Works with Claude, ChatGPT, LangChain, n8n, and any MCP clien
Universal wishlist for AI shopping experiences. Save any product URL from any store to a wishlist. Works with Claude, ChatGPT, LangChain, n8n, and any MCP client.
+W is a universal "save for later" action for commerce. This MCP server lets AI assistants save any product URL to a user's Wishfinity wishlist with one click.
Works with Claude, ChatGPT, Gemini, LangChain, OpenAI Agents SDK, and any MCP-compatible client.
When an AI recommends a product, it can offer +W Add to Wishlist. The user clicks the link, and the product is saved to their Wishfinity account — ready for later purchase or gifting.
User: "Find me a good espresso machine under $200"
AI: Here are 3 options...
[+W Add to Wishlist] [View on Amazon]
Don't need the full MCP server? The /add-wish skill teaches any AI agent the +W pattern using just a URL — no npm, no server, no setup:
https://wishfinity.com/add?url={any_product_url}
→ View the /add-wish skill file
Works with any AI platform. The MCP server below adds richer tool integration, but /add-wish is all you need to get started.
Best for Claude Desktop, ChatGPT Desktop, Cursor, VS Code, and local development.
