@prosperkartik/hostaway-mcp

Model Context Protocol (MCP) server for the Hostaway PMS — connect Claude to your vacation rental ops.

@prosperkartik/hostaway-mcp connects Claude (in Claude Code, Claude Desktop, or any MCP-compatible client) to your Hostaway account — listings, reservations, calendar availability, guest messaging, and financials. Authored by an engineer who has integrated Hostaway, Ciirus, and major OTA APIs (Airbnb, VRBO, Booking.com, Expedia, Marriott) in production for short-term rental operators since 2022.

Hostaway is a trademark of Hostaway Inc. This project is community-built and not affiliated with or endorsed by Hostaway.

Why this server

Three reasons:

1. Tool coverage. 10 read-only tools across listings, reservations, calendar, conversations, financials, and a health-check — broader surface than other community MCP servers in this space.
2. Cleaner auth UX. Takes the two credentials Hostaway gives you on the API settings page — Account ID + API Key — and handles the OAuth token exchange internally. No "go generate a bearer token elsewhere first" step.
3. Built by someone who works the API. The author has 3+ years of production Hostaway / Ciirus integration work behind the design decisions. Tools map to real operator workflows, not just REST endpoints.

Tools (v0.1)

All v0.1 tools are read-only. Write operations are coming in later versions, gated behind explicit confirmation.

Tool	Description
whoami	Health-check — returns connected account counts (listings, reservations, conversations, owner statements, users). Run this first to confirm setup works.
list_listings	List properties on the account
get_listing	Full detail for a single listing — location, capacity, pricing, reputation, channel URLs
list_reservations	List reservations, with optional filters by arrival date range and status
get_reservation	Full detail for a single reservation — guest, dates, pricing, channel
list_calendar	Per-day availability for a listing across a date range — answers "is property X free between A and B?"
list_conversations	List guest message threads with unread state and last activity
list_unread_conversations	Only conversations with unread guest messages — answers "who's waiting on a reply?"
get_conversation_messages	Full message history of a single conversation
list_owner_statements	List owner financial statements

Quick start

1. Get your Hostaway API credentials

In your Hostaway operator account → Settings → Hostaway API. Generate API credentials. You'll get an Account ID and an API Key.

2. Add to Claude Code

claude mcp add hostaway \
  --scope user \
  -e HOSTAWAY_ACCOUNT_ID=your-account-id \
  -e HOSTAWAY_API_KEY=your-api-key \
  -- npx -y @prosperkartik/hostaway-mcp

(Or use --scope local to install for the current project only.)

3. Or add to Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) and add:

{
  "mcpServers": {
    "hostaway": {
      "command": "npx",
      "args": ["-y", "@prosperkartik/hostaway-mcp"],
      "env": {
        "HOSTAWAY_ACCOUNT_ID": "your-account-id",
        "HOSTAWAY_API_KEY": "your-api-key"
      }
    }
  }
}

Restart Claude Desktop. The Hostaway tools appear in the tools picker.

4. Try it

Ask Claude things like:

• "Run whoami to confirm Hostaway is connected."
• "List my Hostaway listings."
• "What reservations are checking in next week?"
• "Is listing 12345 available May 10–17?"
• "Do I have any unread guest messages?"
• "Show me the conversation with [guest]."

Example output (placeholder data)

> List my Hostaway listings.

Found 3 listings:

| ID    | Name              | Location          | Beds | Baths | Capacity | Status |
|-------|-------------------|-------------------|------|-------|----------|--------|
| 10001 | Sample Apt 2BR    | Sample City, US   | 2    | 2     | 4        | active |
| 10002 | Sample Loft       | Sample City, US   | 1    | 1     | 2        | active |
| 10003 | Sample Beachfront | Sample Beach, US  | 3    | 2     | 6        | active |

Configuration

Env var	Required	Description
HOSTAWAY_ACCOUNT_ID	yes	Your Hostaway account ID (acts as OAuth client_id)
HOSTAWAY_API_KEY	yes	Your Hostaway API secret (acts as OAuth client_secret)

The server exchanges those for a bearer token at startup and caches it in memory for the lifetime of the process.

Local development

git clone https://github.com/prosperkartik/hostaway-mcp.git
cd hostaway-mcp
npm install
cp .env.example .env  # fill in credentials
npm run build
npm start

Hot-reload via tsx:

npm run dev

Roadmap

• v0.1 — 10 read-only tools across listings, reservations, calendar, conversations, financials, and health-check
• v0.2 — Tasks (list_tasks, get_task); Cancellation policies; Custom fields read
• v0.3 — Guest payments read; Webhooks read
• v0.4+ — Write operations (send guest messages, update calendar blocks, create tasks) gated behind explicit confirm: true

Security

• Credentials live in environment variables only — never written to disk by this server
• The bearer token lives in process memory; no persistent storage
• v0.1 is read-only end-to-end; nothing in this codebase can mutate Hostaway data
• For multi-property operators: the Hostaway API returns data scoped to the account whose credentials you supply, so cross-account access is not possible

Contributing

Issues and PRs welcome. The codebase is small and easy to read; start at src/index.ts.
