Price Compare

Price Compare MCP is a multip platform price search and comparison server for Taiwan e-commerce. It lets you search across major markets like momo, PChome, Coupang, ETMall, Rakuten, Yahoo Shopping, and Yahoo Auctions to find the lowest prices for your queries, then returns a compact response optimized for large language model usage.

How to use

You use this MCP server through an MCP client or adapter. Start a local MCP server or connect to a remote one, then issue a price query. The server will search across supported platforms and return the lowest-price results in a compact TOON format to minimize token usage. You can filter by platform, apply keyword group filters, and optionally include Yahoo Auctions bids.

## CLI usage with the MCP server

After you have the server configured, you can invoke the price search from your MCP client using the tool name you configured (price-compare). The MCP server will return a compact list of matching products in TOON format to reduce token usage.

## Notes and tips

If you notice unrelated low-priced items on some platforms, you can tighten results with the keyword groups you provide under require\_words to more precisely filter brands and features.
