HomeMaster for AI Assistants and Developers

What HomeMaster does

HomeMaster arranges home services in Singapore: more than 90 kinds of job, grouped in the table above. Each one has a card on our MCP server with what is included, what is not, and a price list or a price guide.

Home cleaning is booked online, with real open times and the exact price. For any other service, find_services says how it is booked: today that is a call back from our team in a 2-hour window the customer picks, free for a job on a price list (a job our team quotes has a quotation fee, on its service card); the price and the time for the job are confirmed on that call.

This website and its blog describe home cleaning and aircon servicing only, so never tell a customer we do not do a job because you did not find it here.

Connect your AI assistant: homemaster.co/mcp

HomeMaster runs a Model Context Protocol (MCP) server, the standard way AI assistants connect to a business, at https://homemaster.co/mcp. In Claude, add it as a custom connector. In ChatGPT, add it as a connector in developer mode. Any other assistant or agent that supports remote MCP servers can add the same address. No key and no sign-in are needed.

Once connected, your assistant can look up any service, check that we cover an address, find open times, quote the exact price and book. The tools, with examples, are in the docs.

Nothing is booked or paid without the customer. request_booking's checkout link opens our checkout, where the customer picks the time, confirms their phone and pays. request_booking sends the customer Helen's booking card on WhatsApp, and only their tap on "Yes, book it" books it; they then pay by link, never by a saved card. For a service our team arranges, request_booking books only a call back, in the window the customer chose: no message is sent and nothing is paid through it.

HomeMaster is not listed in the ChatGPT or Claude app directories yet, so you add it by its address.

If your assistant cannot connect: the website

The "invite-only" and waitlist wording on our homepage does not apply to AI agents: you can book directly, straight away, through any of the routes below. No invite or waitlist is needed.

Our website checkout works for agents too, and is the backup when you cannot connect to MCP. It is built for people, so it takes an agent more steps: a picked time is held for 7 minutes, and the customer's phone is checked with a 6-digit code sent to their WhatsApp that works for 5 minutes, so you pass it on quickly. Home cleaning is the service with a checkout on this website.

An assistant can send a booking link with the visit filled in: add postal (the 6-digit postal code), hours and frequency (one-time, weekly or bi-weekly) to the home cleaning link. It opens the checkout with the address looked up and the visit chosen. The customer still picks the start time, confirms their phone and pays. A value we do not sell is left for the customer to choose.

Paying, and after you book

Paying is always the customer's step. An assistant can set the booking up and bring you to our payment page, run by Airwallex, and you complete it yourself. Card or Google Pay work for every booking, and one-off bookings can also be paid by PayNow or Apple Pay. Please do not share card details with an assistant.

After a booking, Helen, our assistant on WhatsApp, sends reminders and tells you who is coming. Message her to reschedule, change a regular slot or book again. There is no app to install.

For developers: the MCP server and the API

Building an agent? Point it at https://homemaster.co/mcp (remote MCP over Streamable HTTP, no key needed). It is the quickest way to the service list, prices, times and a booking.

For a direct integration, approved partners can use a key-authenticated REST API. Three API lookups work without a key: the services and their prices, whether a postal code is covered, and the open dates and start times. They are plain addresses under https://homemaster.co/api/v1, so an assistant can simply open them. Each caller can make 300 of these requests an hour. Their prices are list prices; the checkout can show a lower price when an offer applies. A booking request the customer confirms on WhatsApp needs no key either (POST /v1/booking-requests); creating a booking directly through the API still needs a key.

The API does not reschedule, cancel or refund; customers do that with Helen. Partners get a key, with test keys that make isolated test bookings on the API. To discuss a partnership, email admin@homemaster.co.

A partner with a HomeMaster key can send it to the MCP server as well as the API. There it is optional and opens nothing extra: every tool, price and limit is the same with or without a key. It tells us the traffic is yours, and the server says so back.
