sitebox/kids-stay-mcp

Verified kid-friendly hotel data for Japan — 1,900+ hotels checked against official sources across 48 kid-friendly conditions (diaper-friendly baths, baby beds, kids' meals, in-room dining, and more), served over the Model Context Protocol.

Built and maintained by Kids Stay (kids-stay.com), a hotel search site for families traveling with babies and toddlers in Japan.

• Endpoint (Streamable HTTP): https://mcp.kidsstay.workers.dev/mcp
• Auth: none — free and open
• Access: read-only, rate-limited (60 req/min per IP)
• Registry: io.github.sitebox/kids-stay (official MCP registry)
• About & terms: https://kids-stay.com/mcp/

Why this exists

Booking sites can't answer questions like "Which hot-spring hotels allow toddlers who aren't potty-trained in the shared bath?" — that information lives deep inside each hotel's official website. Kids Stay reads those sources hotel by hotel and structures them into 48 verified conditions. This MCP server hands that data directly to AI assistants, with sources and verification dates attached.

Tools

Tool	Description
search_hotels	Search by condition IDs × prefecture/area × child age × budget. Returns up to 20 summary cards
get_hotel	Verified details for one hotel: conditions with per-hotel notes, target ages, nearby kid spots, sources
list_conditions	The 48 condition definitions (IDs, labels, EN labels)
list_areas	Hotel inventory per prefecture — useful for narrowing down before searching

Every response includes verified_at (when the data was last checked), sources (official URLs for re-verification), a page link to the hotel's page, and a disclaimer. Data is maintained in Japanese with English labels; translation is left to the agent.

Quick start

Claude (claude.ai / desktop): Settings → Connectors → Add custom connector → paste the endpoint URL.

Claude Code:

claude mcp add --transport http kids-stay https://mcp.kidsstay.workers.dev/mcp

Any MCP client (Streamable HTTP):

{
  "kids-stay": {
    "type": "streamable-http",
    "url": "https://mcp.kidsstay.workers.dev/mcp"
  }
}

Then ask things like: "Find hotels in Okinawa for a family with a 0-year-old — baby bed and baby food required."

Local (stdio): for MCP clients that prefer stdio, this repository ships a zero-dependency local build (index.js, Node.js 18+). Introspection is served locally from the bundled tool definitions; tool calls fetch live data from the hosted endpoint (the single source of truth):

npx github:sitebox/kids-stay-mcp        # or: git clone && node index.js

Data usage

Use in AI responses with attribution (link to the facility page on kids-stay.com) is welcome. Bulk redistribution, resale, or building competing databases is prohibited. Facilities change their services — always confirm current conditions on the hotel page before booking. Full terms: https://kids-stay.com/mcp/ and https://kids-stay.com/terms/

About this repository

The MIT license in LICENSE covers the code in this repository only. The hotel data served by the hosted endpoint is not part of this repository; its terms of use are described at https://kids-stay.com/mcp/ and https://kids-stay.com/terms/.

This repository is the public home of the server metadata (server.json) and a small local stdio build (index.js, MIT-licensed) for registry and directory listings. The hosted implementation and the dataset itself are not part of this repository — the data is the product of ongoing manual verification against official sources, refreshed monthly, and is served only through the endpoint.
