hoteldata

hoteldata

hoteldata is a small local bridge to the hosted HasData Google Hotels MCP server, which returns Google Hotels search results as JSON. Give it a place or a property name together with check-in and check-out dates, and it fetches the matching hotels and vacation rentals: each property's name, link, location, nightly and total rates, hotel class, guest rating and review counts, images, amenities and nearby places, as returned upstream. Searches can be shaped by the guest mix (adults, plus children with their ages), by localisation (country, language and currency), and by a wide filter set covering price range, sort order, property types, amenities, minimum rating, brands, hotel class, free cancellation, special offers, eco-certification, vacation-rental mode with bedroom and bathroom minimums, and paging tokens.

The bridge stores no results of its own. It serves the upstream server's tool list locally, exactly as captured from the live endpoint, and forwards each tool call upstream, returning the result untouched. The captured surface is a single read-only search: there is no booking, reservation or payment tool in it.

Tools

• hasdata_google_travel_hotels_getGoogleHotels — search Google Hotels for one stay. Required: q (the search query: a city, neighbourhood or hotel name), checkInDate and checkOutDate (both in yyyy-MM-dd form). Optional: gl (country), hl (language), currency, adults, children and childrenAges (comma-separated ages matching the child count), sortBy (lowestPrice / highestRating / mostReviewed), minPrice and maxPrice per night, propertyType__ (hotel and rental property types), amenity__ (hotel and rental amenities), rating (minimum guest rating), brands, hotelClass, freeCancellation, specialOffers, ecoCertified, vacationRentals, bedrooms, bathrooms, nextPageToken (paging) and propertyToken (one property's detail). Returns per-property rates, price comparisons, ratings, reviews, amenities, deals and pagination tokens.

Configuration

• HASDATA_GOOGLE_HOTELS_MCP_URL (optional) — override the upstream endpoint. Defaults to https://mcp.hasdata.com/mcp?apis=google_travel_hotels. (The override hook is this rebuild's own labelled reconstruction.)
• HASDATA_API_KEY (optional) — when set, every upstream request carries an x-api-key: <key> header, for the caller's own HasData API key. When it is not set, no key header is sent. (The header name and the env name are pinned by the original's registry record; forwarding the key from this env var is a labelled reconstruction — the original surface was captured keyless.)

Forwarding mechanics

On the first tool call the client opens a streamable HTTP session with the upstream: a JSON-RPC initialize request (protocolVersion 2025-03-26, clientInfo name hoteldata), then a notifications/initialized notification, then the tools/call request carrying the caller's arguments unchanged. When the upstream answers initialize with an Mcp-Session-Id header, that value rides on every later request of the session, which is reused for the life of the process. Replies may arrive as plain JSON or as server-sent events; both are read.

Successful upstream results pass through verbatim, including any isError flag the upstream sets. Failures — a JSON-RPC error, a non-2xx status, an unreadable response, or a request that cannot be completed — come back as an isError result whose text starts with hoteldata error: (this rendering is this rebuild's own labelled reconstruction).

CLI

The tool is also a subcommand taking one JSON argument string:

npx @reneturcios/hoteldata hasdata_google_travel_hotels_getGoogleHotels '{"q":"San Francisco","checkInDate":"2026-11-10","checkOutDate":"2026-11-12","adults":2,"sortBy":"lowestPrice"}'
npx @reneturcios/hoteldata --version

Exit codes: 0 on success, 1 on an isError result, 2 on a usage error.

MCP server

npx -y @reneturcios/hoteldata mcp

MCP client config:

{
  "mcpServers": {
    "hoteldata": {
      "command": "npx",
      "args": ["-y", "@reneturcios/hoteldata", "mcp"]
    }
  }
}

Docker

docker run -i ghcr.io/cloudcorprecords/hoteldata
docker run --rm ghcr.io/cloudcorprecords/hoteldata --version

The container's default command is mcp, so the first form is a stdio MCP server; any other arguments reach the CLI normally.

Development

npm install
npm run build
npm test
npm run dev

The test suite runs entirely against a stubbed JSON-RPC upstream — no live network calls.
