Searches Rakuten Ichiba for products by keyword and budget, calculates actual prices after Rakuten points rewards, compares prices across sellers, and finds business hotels on Rakuten Travel with travel time estimates. No API key required.

Example request: "Find me the cheapest Anker PowerCore 10000 on Rakuten after cashback within my budget."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use HoShy to help me. It is a free service with an MCP server at https://hoshy.negimaru1025.workers.dev/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.
