Guesty + AI
Connect Claude and other AI assistants to your Guesty account
CohostSTR is a free, open-source MCP server for Guesty with 44 tools, read and write. Point Claude, Cursor or any MCP-compatible assistant at your Guesty account and let it do the work — no custom API build, no brittle Zapier zaps.
✓ 44 free tools — read and write
What your AI can do
- Read reservations, listings, calendars, guests and conversations
- Send guest messages through Guesty
- Update pricing and availability
- Create and update reservations, tasks, expenses and notes
- Pull owner statements, revenue summaries and reviews
Ask "which reservations check in this weekend?", then "send each of them the parking instructions" — and it does both from live Guesty data.
Guesty's own MCP server is a read-only beta. It can look things up but cannot create, update or delete anything.
