1barn in Claude and ChatGPT

What it does

1barn has a connector that Claude can use on any plan, and ChatGPT Business and Enterprise workspaces can add. Once connected, you can ask what's due, who owns a horse, which stalls are open, where the signed boarding contract for a horse is, or what's left on today's care round. Staff can also act: log care, add a health record, set an emergency card, send a document for signature, post to the barn's message board, mark a horse injured, or set up an event type with a deposit. With staff scheduling on, staff can ask when they work next, offer or trade a shift, ask a colleague to cover a lesson, request time off or set their availability, and managers can approve those. Clocking in stays on the barn's time clock, not in an assistant. Every call runs as you, with the role your barn gave you, so a boarder sees their own horses and a staff member sees the barn.

What's in it

About 320 tools, grouped by area. Which ones answer depends on your role and on what your barn has turned on.

You and the barn. Who you are and what you can do, your day as the dashboard tells it, everything waiting on you to decide (Open tasks), your notification choices, your name and appearance, unpublished schedule changes and publishing them, and, for the owner, what managers may do. The barn's settings at a glance, and changing them in plain words: the barn's name, time zone and colors, the emergency sheet, kinds of space and vendor, event categories, records email, staffing's rules and time-off policies. The activity log: what changed, who changed it and from what, and undoing a change. Your sign-ins, your calendar links (see them and turn one off), and the AI apps connected to your account.

Horses and people. Horses, their owners and contacts, where each one lives, health status (healthy, injured, rehabbing, sick) and its latest records of each kind, notes, people and their kinds of vendor, organizations (a clinic or a company, with its people), logins and invitations, merging a person filed twice, and keeping a former employee on as a client.

Records and care. What's due, health records (one horse or several at once), renewals, emergency cards, care instructions, the day's round across the barn, marking care done (and taking a mark back), the care log, and owners' care suggestions. The barn's weather.

Records email. What came to the barn's records address, the records the AI suggested from it, adding or dismissing them, and, for the owner and managers, who may send.

Service days. Farrier, vet, vaccine and dentist days: scheduling one, signing horses up or taking them off, and service day forms: the questions a day asks owners, answering them for a horse, reminding owners who haven't, and who the sheet went to. Every owner's answers at once, the file and the emailed or shared sheet stay in the app.

Sign. Templates, forms sent for signature, finding a signed contract by anything written on it, sending, reminding, voiding, and public forms.

Messages. Conversations and broadcasts to the barn, editing your own post, and boards: who can read one, renaming, changing its audience, archiving.

Events. Events and registrants, who has paid or still owes, attendance and check-in, event types with their price and payment terms (full payment or a deposit), add-ons, and bookable events: their open times and the bookings people made. Making an event as a draft and changing it, which events are still drafts, event categories, and the registration questions an event type asks.

Lessons. The calendar, terms, instructor availability, family requests, riders' levels and rider notes (staff and instructors only), horses' lesson programs, and the solvers that propose a timetable and each week's horses.

Money. Customer balances and ledgers, credits, upcoming scheduled charges, lesson billing and a preview of a month's lesson charges, how the business is doing (Admin › Overview), and the day's in-person card payments (reading only), for the owner and managers with the finance permission, at a barn with events or billing.

Staff. The schedule, your own time clock, offering up a shift or a trade, open shifts, lesson covers, time off and paid time-off balances, availability and preferences, employment status, and approving time: a pay period's time entries filtered and sorted (“Who went most over the schedule this week?”), its hours per person with overtime and holidays, approving several entries at once (never ones that look wrong), rejecting one with a reason, clocking out someone who forgot, fixing an entry's times and breaks (“Casey took a 30 minute lunch at noon on Saturday, add it”), adding a day someone forgot to clock, and finding entries still paid with a break typed by hand. Breaks are unpaid and an entry pays them added up, so the assistant changes a break's times, never a break total; each change is shown for a yes first, and none touches a closed pay period. The barn's holiday calendar: reading it, suggesting a year's US holidays (“Add next year's holidays”), adding several at once and changing one in place (whether it's a paid holiday and its paid day), never in a closed pay period. Paid holidays: who gets holiday pay on a day and why someone isn't paid (“Who gets holiday pay on Thanksgiving?”), and, with Pay, setting full-time or part-time, paid holidays and their hours from a day on (“Turn on paid holidays for all full-time staff”), each person's line shown for a yes first. Payroll and hours tell Holiday worked from Holiday paid. For the owner and managers with Pay: what's left before a pay period can close (“What's left before I can close the pay period?”), closing it, and, for the owner only, reopening it with a reason (a manager who asks is offered a message to the owner instead). Managers can also mark a shift out sick, late or cancelled, see what needs them on the schedule, each person's usual shift, availability changes waiting for approval, and the hours report against the labor budget (dollars only with Pay, never one person's). The time clock's devices can be renamed, unlocked or removed; their codes are never shown.

Help and support. Your barn's threads with 1barn support: reading them, writing to 1barn (sent to support@1barn.com), asking for a person, and closing a thread.

New in 1.2.0

Settings, in plain words. Ask what a setting is set to, or change it: “Start our weeks on Monday,” “Turn off web clock-in for Sam.” Anything weighty is shown for a yes first.

Service day forms. The questions a service day asks owners, an owner's answers for one horse, and reminding the owners who haven't answered (“Who still owes answers for Thursday's vet day?”).

Organizations. A clinic or a company is kept with the barn's people, so it can be a horse's vet or a service day's vendor, with its people listed under it.

Activity and undo. “What changed on Belle this week?” shows who changed what, and from what; “Undo that” puts it back, after a yes. Email addresses, phone numbers and form answers aren't shown to an assistant.

Calendar links. See your calendar links and when a calendar last checked each one, and turn one off. Making a new link stays in the app, since anyone with the link can read that calendar.

Connected apps. Which AI apps are connected to your account, when each was last used, and disconnecting one.

Early clock-in rules. Whether someone with a shift later today can clock in early (flagged for a manager, allowed as punched, or prevented until shortly before the start), and asking what the barn's rule is.

Changing employment status. Ending, pausing or restoring someone's employment as one step: the assistant first lists what would happen to their shifts, lessons and requests, then hands them on after a yes.

Health records, told apart from health status. A horse's profile now gives its latest record of each kind (dental, vaccination, Coggins, farrier and more), separate from the history of its health status, so “When did Blaze last see the dentist?” has a straight answer.

Earlier in October 2026

Bookable events. Ask which bookable events the barn has, what times are open next week, and who has booked. You can't book a time for someone from an assistant; share the barn's booking page instead.

Event types, deposits and credits. Set up what the barn offers with its price and payment terms, see who has paid and who owes a balance (amounts for the finance permission), check people in at each session, preview the charges coming up, and give a family a credit with a reason.

Service days. What used to be barn days are service days, with the kind first (“Farrier day”).

Injured and sick horses. A horse marked injured or sick isn't offered for lessons, and the horse solver never places one. A lesson that still has one says so.

Rider notes. A rider's goals, nerves or favorite horse, on each lesson, for staff and instructors only. Families never see them.

Records email. Ask what's waiting in the records inbox and file what the AI suggested (“File the Coggins from Dr. Kim for Blaze”). The assistant sees the sender, the subject, the file names and the suggested records, never the email's text or its files. The owner or a manager can add or approve a sender; the assistant first tells you that email from that sender will be read by AI (Anthropic) and asks you to confirm. See Records email.

Money only where it applies. Balances, credits and charges answer at a barn with events or billing, for the owner and any manager the owner gave the finance permission.

Connect Claude

1. In Claude, open Settings → Connectors and choose Add custom connector (on a Team or Enterprise plan, an owner adds it for the organization first).
2. Enter the URL https://api.1barn.com/mcp and choose Add, then Connect. Free Claude accounts can add one custom connector.
3. A 1barn sign-in page opens: use the email and password you use for 1barn, or sign in with Google.
4. If you belong to more than one barn, pick the one Claude should work in. You can connect again later for another.
5. Back in a conversation, turn the 1barn connector on and ask a question.

Connect ChatGPT

1. ChatGPT lets Business and Enterprise workspaces add custom connectors today; on other ChatGPT plans, 1barn appears once our listing in ChatGPT is approved. A workspace admin opens Plugins, chooses Add custom MCP server, and enters https://api.1barn.com/mcp.
2. Choose Connect. The same 1barn sign-in page opens: email and password, or Google.
3. If you belong to more than one barn, pick the one ChatGPT should work in.
4. Ask a question, or start with @1barn.

On your phone, the same connector lets you talk to your barn: in the Claude app, voice mode can use your connected tools, and in ChatGPT you can dictate into the message box. See Talk to 1barn.

Claude Code and other MCP clients

Any MCP client can use 1barn at https://api.1barn.com/mcp. The server uses OAuth with dynamic client registration, so there is no key to paste: add the URL, and the client opens the same 1barn sign-in page the first time it connects. In Claude Code that's claude mcp add --transport http 1barn https://api.1barn.com/mcp, then /mcp to sign in.

Things to ask

Prompts that work on any barn, with what you should expect back. There are many more, area by area, in What you can ask an assistant.

1. Which horses are due for a Coggins or vaccination this month? A list of horses with each item that's due and the date, overdue first.
2. What's on today's care round, and what's still unchecked? Everything logged today, then what nobody has marked done.
3. Find the signed boarding contract for Apollo. The signed form, who signed it and when, and a link to open it.
4. Which stalls are open? The facility map with empty spaces, and any horse with no home.
5. The farrier did Blaze's feet today. Log it. The assistant confirms the details, then writes the record and tells you when Blaze is due next.

What it will and won't do

Reading is immediate. Anything that changes a record is confirmed with you first, and anything that can't be undone (voiding a contract, ending an assignment, cancelling a registration, approving a records email sender) is marked so the assistant asks plainly. Values in secure form fields such as a license or card number are never returned to an assistant; they open only in the 1barn app, after an emailed one-time code. An owner, or a manager with the finance permission, can record a charge, payment or credit on a customer's account from an assistant; if that customer is billed automatically, a charge is charged to their card on the first of the month like any other, and a credit comes off their next booking or balance. See the privacy policy for what an assistant can see.

What stays in the 1barn app, and why

Some things aren't offered to Claude or ChatGPT on purpose, because they move money or hand over a whole list of people's details at once:

1. Charging a card, saving one, or changing how a customer pays. No assistant tool charges a card.
2. Refunding a registration, moving one to another event (a price difference can refund or ask for money), recording a check or cash, and sending a payment link.
3. Approving or declining a booking that waits for approval: approving charges the card held at booking, and declining releases it.
4. Whole lists at once: every registrant's email, every answer on a form, registration or service day, and the payroll. Pay rates and their history stay in the app too, and so does one person's labor cost.
5. Clocking in and out, and breaks, which stay on the barn's time clock.
6. Files and links that work without signing in: report downloads, a service day's sheet as a file or a shared link, a new calendar link, and a signing link.

The assistant inside 1barn, Ask 1barn, can do some of these, with the same permissions as the app.

Disconnecting

Remove the connector in Claude's or ChatGPT's settings, or disconnect it in 1barn under My profile → Connected apps, which lists each app you've connected, when it was last used and which barns it reaches. A disconnect from 1barn is felt at once: the app's next request is refused at every barn, and nothing else in 1barn changes. See Connected apps.
