your business · inside claude and chatgpt
Ask an assistant to book something with your business.
Today it cannot.
yesmcp builds and runs the connector that lets your customers book, order and get answers from your business right inside Claude or ChatGPT. Like the one in this chat: it is real, and you can try it.

why now
A website in 1998. An app in 2008. A place in AI chats in 2026.
1,000,000,000
people talk to ChatGPT every week, at the very least · OpenAI's own number, Aug 2026 · and that is before counting Claude and Gemini
Late in the evening a customer wants to book or move a visit. Today that waits for the morning shift, and some never write back. With a connector, the assistant settles it on the spot, from your own calendar.
Your customers are done opening ten websites; they ask their assistant instead. The connector is built once, on an open standard the assistant makers themselves handed to the neutral Linux Foundation (December 2025). Each assistant has its own install and approval flow, and we handle that per platform.
what we build
We build one thing: the chat layer of your business
Two jobs, one connector: your team stops digging through tabs, and your customers stop waiting for someone to answer.
lingua studio is an invented school · read it as your business
team connector · 09:00, before the first call
The face your team sees
The same connector, behind a login. The picture of the day lives in five tabs. Your team asks for it in the chat they already sit in, and acts on it.
Morning. What's my day?
9 lessons. One free window at 14:00, and two trial requests waiting. Offer it to both?
Yes, offer it.
customer connector · 21:00, nobody at the desk
The face your customers see
Booking, orders, status, answers grounded in your data, in your customer's own chat. No app, and for guest scenarios no login at all.
Can I move tomorrow's lesson to the weekend?
Saturday 11:00 with Olena K. is free. Move it?
yes
Shown as text on purpose: this is how the same scenario reads in any assistant. In Claude the connector also draws live cards at the moments that decide a sale. The demo at the top is ours, running right now.

Serhii Kravchenko · AI engineer, founder
Every scenario here is designed, tested and run by the person you will actually talk to. You work with the builder, not an account manager.
The routine is run by a team of AI agents Serhii built, which is why your connector is watched every day, weekends included.

Fair questions
Couldn't my own developer build this?
He will. The question is not who writes the server: it is who decides which five of your customers' questions belong in a chat, where the line sits that the assistant may never cross, and who is watching on Friday evening when a scenario starts answering wrongly. We work with your developers on exactly that.
How do my customers actually get the connector?
Today: a one-link install page. A customer adds your connector to Claude in under a minute, on any plan. In ChatGPT the path is the official app directory: OpenAI reviews every submission, and when you want a place there, we prepare and shepherd your submission through that review. We tell you exactly what works today versus what is pending review.
What about our data and security?
Your data stays in your systems: the connector reads them with scoped credentials and never with direct database access. Read and write are separated, and irreversible actions ask for confirmation before they fire. A guest booking stores a name and an email, and that is all; when a scenario truly needs identity, we build it on OAuth 2.1 and run that in production too. And we attack our own server with forged headers and hostile payloads before anyone else gets the chance.
What does it cost, and why is there no price here?
Because every connector is scoped to one business, and a number without that scope would be a guess. The diagnosis is free, and you leave that free step with a number for your case. Two commitments stand in for a price list: if the first scenario turns out to be the wrong one, we build the next one from your map at no extra cost; and against a system with an API, the first scenario takes about two weeks.
Will I be locked into you?
No. The spec and code belong to you from day one, and you can move the connector to your own servers whenever you choose. Clients stay for the work.
