wishfinity/wishfinity-mcp-plusw

**+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.
Zero-dependency option: /add-wish
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:
→ 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.

Option 2: Remote endpoint (HTTP transport)

How it works
1. AI calls the add_to_wishlist tool with a product URL
2. MCP server returns a Wishfinity link: https://wishfinity.com/add?url=...
3. User clicks the link → logs in (first time only) → product is saved
4. User can organize, share, or purchase later
**No API keys required.** Authentication happens on Wishfinity's website when the user clicks the link.

- **After recommending products**: Proactively offer to save shown items
