PriceWin

npx add-mcp 'https://mcp.price.win/mcp'

PriceWin plugin for coding agents

Live hotel and flight prices compared across Booking.com, Agoda, Trip.com and Traveloka, in USD, from inside your coding agent. One package bundles:

• .mcp.json: the PriceWin MCP server, https://mcp.price.win/mcp (Streamable HTTP, no account, no API key);
• 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 same files load in Claude Code, Codex CLI and ZCode: all three read .claude-plugin/plugin.json, the plugin-root .mcp.json and skills/. Antigravity reads the root plugin.json, mcp_config.json and the same skills/; GitHub Copilot CLI reads .plugin/plugin.json with .mcp.json and skills/; Gemini CLI reads gemini-extension.json and skills/. OpenCode takes the server from opencode.json and the skill from ~/.agents/skills.

Install

Claude Code

/plugin marketplace add PriceDotWin/pricewin-agent-plugin
/plugin install pricewin@pricewin

Codex CLI

codex plugin marketplace add PriceDotWin/pricewin-agent-plugin
codex plugin add pricewin@pricewin

Codex asks for approval before PriceWin calls: the search and booking tools reach outside services, and their annotations say so (openWorldHint: true).

GitHub Copilot CLI

copilot plugin install PriceDotWin/pricewin-agent-plugin

copilot mcp list should show pricewin (http) under plugin servers.

Antigravity

agy plugin install https://github.com/PriceDotWin/pricewin-agent-plugin

Gemini CLI

gemini extensions install https://github.com/PriceDotWin/pricewin-agent-plugin

OpenCode

OpenCode needs no plugin: add the server to opencode.json (in the project, or ~/.config/opencode/opencode.json for every project):

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "pricewin": {
      "type": "remote",
      "url": "https://mcp.price.win/mcp"
    }
  }
}

and, optionally, the skill, which OpenCode loads from ~/.agents/skills:

git clone --depth 1 https://github.com/PriceDotWin/pricewin-agent-plugin /tmp/pricewin
mkdir -p ~/.agents/skills && cp -r /tmp/pricewin/skills/pricewin-travel-search ~/.agents/skills/

opencode mcp list should show pricewin as connected.

Cline

Add the server to Cline's MCP settings (cline_mcp_settings.json; in the CLI, ~/.cline/data/settings/cline_mcp_settings.json). Set type explicitly, because Cline otherwise assumes the legacy SSE transport:

{
  "mcpServers": {
    "pricewin": {
      "type": "streamableHttp",
      "url": "https://mcp.price.win/mcp",
      "disabled": false,
      "autoApprove": []
    }
  }
}

No API key or login is needed. Optionally copy skills/pricewin-travel-search into ~/.cline/skills/, which Cline loads as a skill. Tested with the Cline CLI 3.0.68.

Pi and DeepSeek Harness

Both need their own package format, so they have their own repositories with the same server and skill: pricewin-pi and pricewin-dsh.

ZCode

ZCode reads this package format. A listing in the ZCode plugin marketplace is pending; this README will give the install step once it is live.

Then ask, for example:

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

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 plugin sends, and where

The plugin contains no code. It points the agent at one remote MCP server, https://mcp.price.win/mcp, and a skill that tells the agent how to use it.

• 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 account is needed, nothing runs on your machine, and no payment data is ever requested. See the privacy policy and terms of service.
