PriceWin for DeepSeek Harness

Live hotel and flight prices compared across Booking.com, Agoda, Trip.com and Traveloka, in USD, from inside DeepSeek Harness. This is a DSH plugin bundle; its cordis.patch.yml adds two entries to the profile:

• pricewin-mcp: @deepseek-ai/dsh-mcp-client connected to the PriceWin MCP server, https://mcp.price.win/mcp (Streamable HTTP, no account, no API key);
• pricewin-skills: a @deepseek-ai/dsh-skill-filesystem provider that serves only this package's skills/pricewin-travel-search: how to run a search (results arrive in two steps), what to ask when the trip details are incomplete, and how to read prices and links.

The package contains no code of its own.

Install

dsh plugin --profile web add @pricewin/dsh

or from GitHub:

dsh plugin --profile web add github:PriceDotWin/pricewin-dsh

Use the name of your profile in place of web. You can also add it from the Plugins page in the Web sidebar. Then ask, for example:

Compare hotel prices in Da Nang for 2 adults from November 10 to 12.

The tools appear as mcp__pricewin__<tool>.

Tested with DSH 0.2.0-rc.2 (dsh --profile headless). DSH is a preview and its configuration format still changes; if a newer version refuses the bundle, please open an issue.

Tools

Tool	What it does
search_hotels_live, poll_search_results	Search a city's hotels across the OTAs and OpenTravel partner hotels; results arrive in two steps
search_flights_live, poll_flight_results	Search one-way or per-leg round-trip fares
get_ota_hotel_detail	Rooms, live prices, facilities and reviews for one named hotel (Booking.com)
get_hotel_detail, get_hotel_info	Rooms and prices, or facilities and policies, of an OpenTravel partner hotel
get_cancellation_policy	Refund terms for one rate
request_booking, check_booking_status	Send a booking request to a partner hotel and read its status
request_cancel_token, cancel_booking	Cancel such a booking, in two steps

Booking takes no money. request_booking sends the guest's name, phone and email to the hotel, which confirms the request; no room is held and the guest pays at the property. Cancelling needs a single-use token that is emailed to the address on the booking, so nothing is cancelled without the guest's own inbox.

What the bundle sends, and where

DSH talks to one remote MCP server, https://mcp.price.win/mcp.

• To mcp.price.win: the arguments of each tool call, which are trip details (city, dates, party size, hotel name, price range, airports, cabin), a short excerpt of the request used only to pick the reply language, and, for a booking request, the guest's name, phone number and email.
• Onward from PriceWin's server: only to PriceWin's own backend and to OpenTravel's API (api.travelopen.ai), which the PriceWin developer also owns. A booking request's name, phone and email go to the partner hotel through OpenTravel, so the hotel can confirm it.
• Usage analytics: PriceWin records trip parameters only (city, dates, party size, hotel name, currency), never a guest's name, email, phone, confirmation code or cancel token.
• Where prices come from: PriceWin's backend reads Booking.com, Agoda, Traveloka, Trip.com and Google Flights from their public pages at search time. PriceWin has no partnership with those sites. Each result is labelled with its source and links to it for booking. Prices are time-sensitive.

No payment data is ever requested. See the privacy policy and terms of service.

The same server and skill are packaged for Claude Code, Codex CLI, Antigravity and OpenCode in pricewin-agent-plugin, and for Pi in pricewin-pi.
