Booksy API and MCP server: connect Booksy to ChatGPT and Claude

Yes, ChatGPT, Claude and other AI agents can work in your Booksy account. That includes Cursor, Codex, OpenClaw and any MCP client, plus automations in n8n, Make and Zapier. Ask in plain words, and the AI reads your calendar and open slots, finds clients who have not been back, moves bookings when someone is off, answers reviews and compares revenue per staff member. It shows you what it will do first and sends nothing to other people until you say so.

As of November 2026, this repo is the missing piece: 28 Booksy tools for AI assistants and scripts.

What you can ask

What does tomorrow look like? List the appointments and any gaps longer than an hour.

Tom is off on Friday. Move his bookings to whoever is free at about the same time, and show me the plan first.

Compare last week's revenue per staff member with the week before.

Which clients have not been in for 60 days and have nothing booked?

Run it yourself

A Booksy API and a Booksy MCP server you run on your own computer, in Python, on the session of your own Google Chrome. All 28 Booksy Biz tools we run in production at Cotlet: the calendar, open slots, time off, clients, services and staff, reviews, Message Blasts and Stats & Reports.

Booksy has no self-serve API for business owners and no official MCP server. This repo gives you both:

• MCP server for Claude Code, Claude Desktop, Cursor, Codex and any MCP client, over stdio or HTTP. Setup

• REST API on http://127.0.0.1:8787/api/v1/booksy, with OpenAPI docs at /docs. Setup

• Python: call("list_appointments", {"from": "2026-10-27", "to": "2026-10-27"}), plus 9 ready scripts in examples/.

Free for your own use, your own business included (license).

Questions from Booksy users

Does Booksy have an API? Not one a business owner can use. Booksy runs a partner API whose docs at docs.booksy.com ask for a login, so you cannot get keys for your own account (checked 11 Oct 2026). Stats & Reports and Message Blasts are not among its public areas. This repo and Cotlet give you 28 Booksy tools as a REST API and an MCP server.

Can I get a Booksy API key? Not from Booksy for your own account. With Cotlet you get your own API key that works with your Booksy account, for scripts, n8n, Make, Zapier or any HTTP client. This repo needs no key: it runs on your computer, on your own Booksy session.

Is there an official ChatGPT integration for Booksy? Booksy has a ChatGPT app for clients: it finds pros and books open slots. It does not run your business. Cotlet connects your Booksy Biz account to ChatGPT, Claude and other AI agents: your calendar, clients, staff, reviews, Message Blasts and stats.

How do I connect Booksy to ChatGPT? Sign up at cotlet.dev, sign in to Booksy once in your Cloud Browser there, and add Cotlet to ChatGPT, following the steps in your account. Then ask ChatGPT about your Booksy like you would ask an assistant. ChatGPT needs a server on the internet, so this repo alone, running on your computer, does not connect to ChatGPT.

Can ChatGPT manage my Booksy calendar? Yes, with Cotlet. It lists tomorrow's appointments and gaps, finds open slots, blocks time off and plans moves when a staff member is off. It shows you the plan before it changes anything.

Can AI bring back Booksy clients who stopped booking? Yes, with Cotlet. It finds clients who have not been in for a while and have nothing booked, so you can send them a Message Blast or a personal note.

Can I automate Booksy with Zapier, Make or n8n? We could not confirm a Booksy Zapier app. With Cotlet, n8n, Make and Zapier can read appointments and clients and send Message Blasts, for example to copy new bookings into a Google Sheet.

Can I use it from my phone? Yes, with Cotlet: once it is set up, the ChatGPT and Claude apps on your phone can use Booksy for you.

Do I need to be technical? For Cotlet, no: you sign in to Booksy and add Cotlet to ChatGPT or Claude, with step-by-step instructions in your account. This repo is for people who are fine with Python and a terminal.

Is my Booksy account safe? Yes. Neither Cotlet nor this repo sees or stores your Booksy password. You sign in yourself, the way you always do, and the AI works on that signed-in session. Anything that reaches other people asks for your OK first: in Cotlet by default, here through your MCP client.

Is it free? This repo is free, also in your own business. Cotlet is free for 7 days with no card, then one-time credit packs from $29, no subscription. Pricing.

I manage Booksy for several accounts or clients. Does that work? Yes, with Cotlet. Each Booksy login gets its own connection. Write to contact@cotlet.dev and tell us how many accounts you manage.

How it works

AI agent (MCP) / script (REST, Python) ──▶ booksy-mcp on your computer ──your Booksy session──▶ <country>.booksy.com
                                                   ▲
                         booksy-mcp connect ───────┘ reads it once from your Chrome (DevTools Protocol)

1. You sign in to Booksy Biz in your own Chrome at booksy.com/pro, the way you always do.

2. booksy-mcp connect attaches to that Chrome through the Chrome DevTools Protocol and reads your session. Booksy does not keep it in a cookie. The panel stores it in the localStorage of its web-gateway.booksy.com frame, so connect reads that storage, the booksy.com cookies and the panel's country, and saves them to ~/.config/booksy-api-mcp/session.json, readable by your user only. It never sees or stores your password.

3. Every tool call is a request to the API the Booksy Biz web panel calls (<country>.booksy.com/core/v2, so us.booksy.com for a US business and pl.booksy.com for a Polish one), sent with curl_cffi, which copies Chrome's TLS fingerprint. No headless browser runs.

When Booksy signs you out, the server reads the session from Chrome again, if Chrome is open with remote debugging on.

Requirements

• Python 3.11 or newer.

• Google Chrome 144 or newer, signed in to Booksy Biz. Any Chrome or Chromium works with a debugging port.

• macOS, Linux or Windows.

• A Booksy Biz owner account. Some reports, such as Staff Members, need Booksy Biz Pro. Booksy sends one-time Message Blasts on a paid plan only, not during the free trial.

Install

From PyPI:

uv tool install booksy-api-mcp       # or: pipx install booksy-api-mcp, or: pip install booksy-api-mcp
booksy-mcp --version

MCP clients can also run it with no install: uvx booksy-api-mcp mcp.

From source:

git clone https://github.com/cotletdev/booksy-api-mcp-server.git
cd booksy-api-mcp-server
python3 -m venv .venv
. .venv/bin/activate              # Windows: .venv\Scripts\activate
pip install -e .
booksy-mcp --version

With uv: uv venv && uv pip install -e ., then uv run booksy-mcp ....

Setting it up with an AI agent (Claude Code, Codex, Cursor)? Open it in this folder and ask it to set up the repo: AGENTS.md tells it every step, and it asks you only for the steps in Chrome.

To update: uv tool upgrade booksy-api-mcp (or pip install -U booksy-api-mcp), from source git pull && pip install -e .. We copy every change of the hosted Booksy tools into this repo.

Connect your Chrome

Option A: your everyday Chrome (recommended)

1. Open chrome://inspect/#remote-debugging in Chrome and switch remote debugging on. Chrome then accepts DevTools connections from programs on this computer, and asks you before each one.

2. Make sure you are signed in to Booksy Biz at booksy.com/pro. Keep a tab of the panel open, because connect reads the session in it. With no Booksy tab open, it opens one in the background and closes it again.

3. Run:

   booksy-mcp connect

4. Chrome asks whether to allow the connection. Click Allow.

Saved 41 Booksy cookies and 50 localStorage keys to /Users/you/.config/booksy-api-mcp/session.json
Signed in to Booksy as Maria Lopez (Studio Maria)

You can switch remote debugging off again afterwards. Leave it on if you want the server to pick up a new session by itself after Booksy signs you out.

connect looks for Chrome's DevToolsActivePort file in the default profile folder. For Chrome Beta, Canary or a custom profile folder, pass --profile-dir "<folder>".

Option B: a Chrome with a debugging port

Chrome does not open a debugging port on your default profile, so start a separate one, sign in to Booksy Biz there once, and connect to it:

# macOS
"/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" --remote-debugging-port=9222 --user-data-dir="$HOME/.chrome-booksy"
# Linux
google-chrome --remote-debugging-port=9222 --user-data-dir="$HOME/.chrome-booksy"
# Windows
"C:\Program Files\Google\Chrome\Application\chrome.exe" --remote-debugging-port=9222 --user-data-dir="%USERPROFILE%\.chrome-booksy"

booksy-mcp connect --cdp http://127.0.0.1:9222

--cdp also takes a ws:// DevTools URL, for example of a Chrome on another machine reached over an SSH tunnel.

There is no option to paste a cookie by hand, since Booksy has no session cookie. A server with no Chrome can use a session.json copied from a machine where connect ran.

Check the session at any time:

booksy-mcp status

MCP server

The MCP server lists every tool with its input schema, a description written for agents, and hints. Read tools are marked read-only, and tools that reach clients (bookings, reschedules, cancellations, review replies, blasts) are marked so your client asks before running them.

Claude Code

claude mcp add booksy -- uvx booksy-api-mcp mcp
# read only:
claude mcp add booksy -- uvx booksy-api-mcp mcp --read-only

Claude Desktop

~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "booksy": {
      "command": "uvx",
      "args": ["booksy-api-mcp", "mcp"]
    }
  }
}

Cursor

~/.cursor/mcp.json, the same block as Claude Desktop. A ready copy is in mcp.json.

Codex

~/.codex/config.toml:

[mcp_servers.booksy]
command = "uvx"
args = ["booksy-api-mcp", "mcp"]

Over HTTP

booksy-mcp serve also serves MCP over streamable HTTP at http://127.0.0.1:8787/mcp, for clients that take a URL:

booksy-mcp serve
claude mcp add --transport http booksy http://127.0.0.1:8787/mcp

Then ask your agent things like:

What does tomorrow look like? List the appointments and any gaps longer than an hour.

Tom is off on Friday. Move his bookings to whoever is free at about the same time, and show me the plan first.

Compare last week's revenue per staff member with the week before.

Which clients have not been in for 60 days and have nothing booked?

REST API

booksy-mcp serve                   # http://127.0.0.1:8787, MCP at /mcp, docs at /docs

Each tool has its own route under /api/v1/booksy, the same paths as the hosted API at cotlet.dev, so code written against one works with the other. Path parts and the query string are arguments, and a JSON body adds the rest.

curl 'http://127.0.0.1:8787/api/v1/booksy/services'
curl 'http://127.0.0.1:8787/api/v1/booksy/appointments?from=2026-10-27&to=2026-10-31'
curl 'http://127.0.0.1:8787/api/v1/booksy/services/8307205/open-slots?date=2026-10-27'
curl -X POST http://127.0.0.1:8787/api/v1/booksy/staffs/882081/time-offs \
  -H 'Content-Type: application/json' \
  -d '{"start": "2026-11-02", "end": "2026-11-06", "reason": "vacation"}'

Any tool by name, body as its arguments:

curl -X POST http://127.0.0.1:8787/api/v1/booksy/tools/find_client -d '{"query": "nowak"}'

• GET /api/v1/booksy/tools: every tool with its route, input schema and an example answer.

• GET /docs: interactive OpenAPI docs, GET /openapi.json the schema, for n8n, Postman or a generated client.

• Answers are JSON. list_clients returns next_cursor; pass it back as cursor for the next page. Reviews and notifications take page.

The server listens on 127.0.0.1 only. To reach it from another device of yours, set a token, and every request then needs Authorization: Bearer <token>:

BOOKSY_MCP_TOKEN=$(openssl rand -hex 24) booksy-mcp serve --host 0.0.0.0

Python and the example scripts

Straight from Python, no server needed:

from booksy_api_mcp import call
from booksy_api_mcp.scripting import paginate, write_rows

services = call("list_services")["services"]
day = call("list_appointments", {"from": "2026-10-27", "to": "2026-10-27"})["appointments"]
clients = list(paginate("list_clients", {"not_visited_days": 60, "limit": 100}, "clients"))
write_rows(clients, "slipping-away.csv")
call("add_time_off", staff_id="882081", start="2026-11-02T13:00", end="2026-11-02T14:00", reason="Lunch")

Or one tool from the shell: booksy-mcp call find_open_slots service_id=8307205 date=2026-10-27, or with a JSON object. An ID stays text where the tool takes text.

Times are local to the business. A date-time without a zone is read in the business's time zone, and answers carry its offset.

Ready scripts in examples/. Each prints JSON or a short list, takes --out file.csv or --out file.json where it makes sense, and --help:

python examples/tomorrows_appointments.py --open-slots-for 8307205
python examples/reschedule_day.py --staff-id 882081 --date 2026-10-27
python examples/export_clients.py --not-visited-days 60 --out slipping-away.csv

On a schedule, cron on your own computer works while it is on: 0 19 * * * cd ~/booksy-api-mcp-server && .venv/bin/python examples/tomorrows_appointments.py.

All 28 tools

IDs come from the list tools: service_id from list_services, staff_id from list_staff, client_id from list_clients or find_client, appointment_id from list_appointments. booksy-mcp tools prints this list, booksy-mcp tools --json adds the input schemas.

Stats & Reports

Writes run Booksy's own dry run first, and send the client no notice unless you pass notify_client. New clients get no invitation. send_message_blast refuses an empty client list, because Booksy reads an empty list as every client.

Never built, on purpose: your Booksy sign-in, email, password and account deletion, and anything that moves money (subscription, payments, payouts, billing). Every request passes a guard that refuses those Booksy paths.

Configuration

Security and your Booksy account

• Your password never reaches this code. Only the session the panel already keeps is read, and only that of booksy.com.

• The session file is yours. session.json is created with mode 0600 and holds your Booksy access token. Anyone who has it can act as you in Booksy Biz, so keep it out of git and shared folders.

• Local by default. serve binds to 127.0.0.1 and refuses another address without BOOKSY_MCP_TOKEN.

• booksy.com only. Requests and redirects outside booksy.com are refused.

• Read-only mode. --read-only or BOOKSY_MCP_READ_ONLY=1 exposes the 17 read tools only.

• Actions reach real people. A booking, a move with notify_client, a cancellation, a review reply and a blast reach your clients. MCP clients ask before running them; a script does not, so try it on a test client of your own first.

• Do not spam. Blasts to people who did not agree break Booksy's rules and the law in many countries. You are responsible for what runs in your account.

Errors

The REST API answers {"error": "<code>", "message": "..."}. The MCP server returns the same code and message as a tool error.

Self-hosted or hosted

On the hosted version a successful call uses 10 credits for most tools, failed calls are free, and the Cloud Browser uses 50 credits a day while it has an app enabled for agents. Full pricing.

FAQ

Is there a Booksy MCP server for Claude, ChatGPT or Cursor? Yes, this one runs on your machine: booksy-mcp mcp for Claude Code, Claude Desktop, Cursor and Codex. ChatGPT and Claude.ai connectors need a public HTTPS URL, which the hosted Booksy MCP server gives you.

Is there a Booksy Zapier app? We could not confirm one. Owners who want bookings elsewhere forward Booksy confirmation emails to a Zapier email parser. That copies new bookings one way and cannot change anything in Booksy.

Can I export my Booksy clients to CSV? Yes: python examples/export_clients.py --out clients.csv. Every client card with contact details, note, visits, no-shows, revenue and last visit, across all pages.

Can it find free slots and book for me? find_open_slots gives the free starts for a service on a day, per staff member, each checked with Booksy's own dry run. create_appointment books one of them for a client, and the client hears about it only with notify_client.

Can it send Message Blasts? Yes, send_message_blast by email, SMS or push, on a paid Booksy plan. Run estimate_message_blast first for the reach and the SMS cost. In the EU only clients who gave marketing consent get it.

Does it work outside the US? Yes. Booksy runs a separate API per country, and the server picks it from your session: us.booksy.com, pl.booksy.com, es.booksy.com and so on.

Why does it need my Chrome? To read your Booksy session without your password. Chrome is used once per sign-in, not for each call.

What happens when Booksy signs me out? Calls fail with auth_expired. With Chrome remote debugging on, the server reads the new session on the next call (click Allow when Chrome asks). Otherwise run booksy-mcp connect again.

Can it run on a VPS or in Docker? Technically yes, with a session.json copied from your computer. Booksy then sees your session from a datacenter IP, which looks less like you. For an always-on setup the hosted version keeps your session in your own Cloud Browser on a fixed IP.

Will my Booksy account get banned? Requests carry Chrome's fingerprint and go out one at a time, as you would click. Nobody can promise a platform never acts. Keep to your normal use and do not blast people who did not agree.

Can I use it for my salon or for my clients? For your own salon, yes, free. You may not offer it to others as a hosted or managed service. For client work, use Cotlet or write to contact@cotlet.dev.

Is it open source? The source is public under the Elastic License 2.0: free to use and change, also in your own business, but not to resell as a hosted service.

A tool broke or I need another one. Open an issue with the tool name and the error message.

License

Elastic License 2.0. In short:

• Allowed: using it for yourself and in your own business, free. Changing the code and sharing it under the same license.

• Not allowed: offering it to others as a hosted or managed service, removing the license notices, getting around its limits.
