+W MCP Server (Wishfinity)
+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.
What it does
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.
Quick start
Option 1: Local installation (stdio transport)
Best for Claude Desktop, ChatGPT Desktop, Cursor, VS Code, and local development.
Add to your MCP client configuration:
Option 2: Remote endpoint (HTTP transport)
Best for server-side agents, LangChain production deployments, and hosted AI applications.
