resOS MCP by usefulapi

Use your resOS account from Claude, Cursor, or any MCP client. It reads bookings, guests, feedback and availability, and it can create, change or cancel bookings and post guest comments. Hosted, no local install: connect with your own credentials.

Live endpoint: https://resos.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://resos.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http resos https://resos.usefulapi.io/mcp, then run /mcp to log in.
• VS Code: Add to VS Code.
• Cursor and other clients: add the URL as a remote MCP server:

{
  "mcpServers": {
    "resos": {
      "url": "https://resos.usefulapi.io/mcp"
    }
  }
}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your resOS credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/resos/

On first connect you provide your resOS API key (Settings → API integration; the API is a paid add-on). The server validates it and stores it per user. No keys go in config files.
