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.

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
npm test
npm run typecheck
npm run build
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.
