Nowistay is compatible with the Model Context Protocol (MCP), the open standard that lets AI assistants like ChatGPT, Claude, and Gemini connect directly to your property management tools. Once connected, you can talk to your favorite AI assistant and ask it to read your bookings, update your calendar, manage your welcome guide, create cleaning missions, and much more — all without leaving the conversation.
This guide walks you through the setup for each platform, step by step.
Prerequisites
Before you begin, make sure you meet these two requirements:
- Your properties must be connected via Nowistay PMS — only properties using Nowistay as their channel manager are accessible through the MCP integration. Properties connected through other channel managers (Beds24, Smoobu, Lodgify) are not available via MCP.
- You need an active AI assistant subscription — the MCP integration is part of the AI co-host feature. If you don't have an active subscription, you'll see an error when trying to authenticate.
You can check both requirements from your Integrations page in the Nowistay app.
The MCP server URL
All platforms require the same server URL to connect:
https://api.nowistay.com/mcp
Keep this URL handy — you'll need to paste it during setup.
Setup with ChatGPT (web)
ChatGPT supports MCP through its Applications feature. Here's how to set it up:
- Open ChatGPT on the web.
- Go to Applications, then click Advanced settings.
- Enable Developer mode. When ChatGPT shows a security warning about the MCP server, click "I understand and wish to continue" to confirm.
- Click "Create an app".
- Set the app name to Nowistay, choose an icon, paste the server URL (
https://api.nowistay.com/mcp), then select OAuth as the authentication method. - Save the app, then sign in to Nowistay and approve access when prompted.
- Open a new chat, select the Nowistay app, and start asking questions or requesting updates.
Note: ChatGPT features and available actions depend on your OpenAI plan. If you don't see the Applications section, or if write actions are unavailable, your plan may not support full MCP integration yet.
Setup with Claude (web or desktop app)
If you use the Claude app on the web or desktop, you can add Nowistay as a connector:
- Open Claude on the web (claude.ai) or on the desktop app.
- Go to Settings > Connectors.
- Click Add a custom connector and paste the server URL:
https://api.nowistay.com/mcp - Sign in to Nowistay and approve access when prompted.
- Start a new chat and you'll see the Nowistay tools available.
Setup with Claude Code (terminal)
If you use Claude Code in the terminal, the setup is a single command:
- Open your terminal and run the following command:
claude mcp add --transport http nowistay https://api.nowistay.com/mcp - Open Claude Code and type /mcp to verify the server is listed.
- Click Authenticate, sign in to Nowistay, then approve access.
- You're ready — ask Claude to check your bookings, update your calendar, send guest messages, or edit your welcome guide.
Setup with other AI assistants
Any AI assistant that supports the MCP protocol with HTTP transport and OAuth authentication can connect to Nowistay. This includes tools like Google Gemini, Cursor, Windsurf, and more as they add MCP support.
The principle is always the same:
- Find the MCP or connector settings in your AI tool.
- Add a new server with the URL:
https://api.nowistay.com/mcp - Choose OAuth as the authentication method.
- Sign in to Nowistay and approve access.
How authentication works
When you connect an AI assistant for the first time, you'll be redirected to the Nowistay login page. After signing in, you'll see an authorization screen showing:
- The name of the application requesting access (e.g., "ChatGPT" or "Claude").
- Your Nowistay account information.
- The permissions the app is requesting — reading bookings, updating the calendar, managing missions, etc.
Click "Approve" to grant access. The connection is secure: your password is never shared with the AI assistant, and you can revoke access at any time.
Troubleshooting
- "Assistant subscription required" — make sure your AI assistant subscription is active. Check your subscription settings.
- "Property not found" — the property must be connected via Nowistay PMS. Properties using other channel managers are not available through MCP.
- The app doesn't appear in ChatGPT — make sure Developer mode is enabled in Applications > Advanced settings.
- Menu names look different — menu labels may vary slightly depending on the app version and your plan.
