Zenoti MCP Server

A Model Context Protocol (MCP) server for the Zenoti spa/wellness/medspa management platform. Exposes appointments, guests, service booking, invoices, catalog, and forms as tools an AI agent can call.

Hosted version available

Do not want to manage credentials, hosting, and updates yourself? DOCK is the managed version of this server: encrypted per-practice auth, audit logs, draft-first write actions, and a workflow library. Founding practices lock lifetime pricing: Front Desk $49/mo (Zenoti), Billing Desk $99/mo (Tebra, BAA included), Full Practice $129/mo (both). https://dockhq.vercel.app

Installation

npm install -g zenoti-mcp-server

Or run from source:

git clone https://github.com/tacit-code/zenoti-mcp-server.git
cd zenoti-mcp-server
npm install
npm run build

Configuration

Variable	Required	Description
ZENOTI_API_KEY	yes	API key from Zenoti Admin → Settings → Apps (create a backend app)
ZENOTI_API_URL	no	Base URL, default https://api.zenoti.com (with or without /v1)
ZENOTI_CENTER_ID	recommended	Default center GUID; tools accept center_id to override per call

Claude Desktop / Claude Code config:

{
  "mcpServers": {
    "zenoti": {
      "command": "npx",
      "args": ["-y", "zenoti-mcp-server"],
      "env": {
        "ZENOTI_API_KEY": "your_api_key",
        "ZENOTI_CENTER_ID": "your_center_guid"
      }
    }
  }
}

The server starts even without credentials and returns a readable configuration error on each tool call, so a misconfigured client shows the problem instead of crash-looping.

Tools

Catalog

Tool	Purpose
zenoti-centers-list	List organization centers (find center GUIDs)
zenoti-services-list	Services of a center (compact by default, verbose for raw)
zenoti-services-get	Full service details
zenoti-therapists-list	Therapists of a center, optionally filtered to a service
zenoti-employee-schedules	Who is on shift for a date range (date-scoped staffing)

Guests

Tool	Purpose
zenoti-guests-search	Search by name/email/phone/code/tags (≥1 criterion required)
zenoti-guests-create	Create a guest profile
zenoti-guests-get	Guest details by GUID
zenoti-guests-update	Update fields — does a safe read-merge-write (Zenoti replaces the whole object on update)
zenoti-guests-appointments	Appointment history for a guest
zenoti-guests-notes-list / zenoti-guests-notes-add	Guest notes and profile alerts
zenoti-guests-memberships	Guest's memberships (status, credits, dues)
zenoti-guests-packages	Guest's packages/series with remaining redemptions

Appointments

Tool	Purpose
zenoti-appointments-list	Center appointments for a date range (compact by default)
zenoti-appointments-get	Appointment details (appointment_id)
zenoti-appointments-checkin / zenoti-appointments-undo-checkin	Check-in state (appointment_group_id)
zenoti-appointments-noshow	Mark no-show (appointment_group_id)
zenoti-appointments-progress	Start/open/complete service (appointment_id)
zenoti-appointments-cancel	Cancel a booking (by invoice_id)
zenoti-appointments-reschedule	Start a reschedule (creates a booking draft tied to the invoice)

Booking flow

1. zenoti-availability-slots — creates a booking draft for guest+service+date and returns booking_id plus open slots
2. zenoti-booking-reserve — hold a chosen slot (holds are short-lived)
3. zenoti-booking-confirm — finalize; the response includes the invoice

Invoices

Tool	Purpose
zenoti-invoices-get	Invoice with line items, payments, and optional dues/fees
zenoti-invoices-pay-custom	Record a cash/custom payment (financial action)
zenoti-invoices-pay-card	Charge the guest's card on file (financial action)
zenoti-invoices-close	Close a fully-paid invoice
zenoti-invoices-email	Email the receipt/invoice to the guest
zenoti-invoices-confirm-visit	Confirm (or undo-confirm) the visit — a scheduling status, despite living on the invoice

Reports

Tool	Purpose
zenoti-reports-sales	What was sold over a date range
zenoti-reports-collections	Money received over a date range

Forms & feedback

Tool	Purpose
zenoti-forms-list / zenoti-forms-get	Forms and submitted form data of an appointment
zenoti-guest-forms-list	Forms on a guest profile
zenoti-feedback-submit	Insert externally collected guest feedback

Zenoti API gotchas this server handles

• Three identifiers in one workflow. Check-in/no-show/feedback take appointment_group_id; details/progress/forms take appointment_id; cancel and payments take invoice_id. Tool schemas name the exact one required.
• Guest updates replace the whole object. The update tool fetches the current profile and merges your changes; a naive partial PUT would erase fields.
• Rate limit is 60 calls/minute (org-wide). The HTTP layer honors Retry-After on 429. Reads also retry on 5xx/network failures/timeouts; writes retry only on 429 (a rate-limit rejection was never processed, so retrying can't duplicate a booking — any other write failure surfaces immediately).
• Pagination caps at size=100; larger values are rejected by Zenoti with a 422.
• Webhooks have no subscription API — they are configured in the Zenoti web UI (Admin → Webhooks) and require the Zenoti API package. This server intentionally has no webhook tool.
• Undocumented numeric enums. Gender and appointment-progress codes aren't in Zenoti's public docs; the mappings used here are documented in the tool descriptions and can be overridden (progress_code).

Development

npm run dev        # run from source (tsx)
npm test           # unit + end-to-end tests (mock Zenoti API; no real credentials needed)
npm run typecheck  # tsc --noEmit
npm run build      # emit dist/

The e2e suite spawns the real server over stdio via the MCP SDK client and asserts every tool's method, path, query, and body against Zenoti's documented endpoints.
