What you can do with Appointo in Claude and ChatGPT

For Shopify merchants who take bookings with Appointo.

See upcoming or past bookings

The AI lists bookings, upcoming or past or by search, with time, product, duration, quantity, price and the customers' name, email and phone.

Find open time slots for a service

The AI lists the bookable products and their services, then reads the open time slots of one service from a start date.

Review cancelled bookings

The AI lists cancelled bookings with time, product and customers, so you can see what was cancelled and for which service.

Review recurring booking subscriptions

The AI lists subscription contracts of customers who repeat appointments, searched by product, variant, order number or customer name.

Book a customer into an open slot

The AI checks the open slots of a service and creates a booking for a customer at the slot you choose. Appointo may email the customer.

Changes data

Reschedule or cancel a booking, or set its buffer times

The AI checks open slots, moves a booking to a new slot, cancels it or only some of its customers, or sets the minutes blocked before and after it.

How do I connect Appointo?

Before you connect

The login page asks for your Appointo API token.

Find it in the Appointo app under Plans & Settings → API access (API access is available on paid Appointo plans). Your token is used only to call the Appointo API on your behalf; it is never shown to anyone.

Claude claude.ai · Desktop

Open Customize → Connectors, then click + Add → Add custom connector.
Enter the name Appointo and this URL, then click Add:
https://appointo.usefulapi.io/mcp
Claude opens the login page: enter your Appointo API token.
In a chat, click + → Connectors and turn on Appointo.

Team and Enterprise: an Owner adds the connector for the organization first.

ChatGPT chatgpt.com

Open Plugins, click +, then Add custom MCP server.
Enter the name Appointo and this URL, choose OAuth as the authentication, confirm the warning and create it:
https://appointo.usefulapi.io/mcp
ChatGPT opens the login page: enter your Appointo API token.
In Plugins, install Appointo, then choose it in a chat.

No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.

Claude Code

Run this command, then run /mcp in Claude Code to log in:

claude mcp add --transport http appointo https://appointo.usefulapi.io/mcp

Cursor

Add to Cursor or add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "appointo": {
      "url": "https://appointo.usefulapi.io/mcp"
    }
  }
}

VS Code

Add to VS Code or add this to .vscode/mcp.json:

{
  "servers": {
    "appointo": {
      "type": "http",
      "url": "https://appointo.usefulapi.io/mcp"
    }
  }
}

Codex

Run these commands. The second one opens the login page:

codex mcp add appointo --url https://appointo.usefulapi.io/mcp

codex mcp login appointo

Other clients

Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.

https://appointo.usefulapi.io/mcp

Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Appointo API token. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

Pricing

Plan	Price	Limit
Free	$0	50 tool calls / month
Proper user	$9/mo · $90/yr	10,000 tool calls / month
Pro+per user	$39/mo · $390/yr	100,000 tool calls / month

Each paid plan covers this Appointo server only. Ask your AI to run appointo_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with appointo_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with appointo_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

List bookable productsappointo_list_products

List appointments (bookable services)appointo_list_appointments
List appointments, i.e. the bookable services/variants, with name, price, currency and configuration. Filter by product or fetch one by id. These are the services customers book, not the bookings themselves (use appointo_list_bookings for those).

Create bookingappointo_create_booking
WRITE: create a booking for a customer on an appointment (bookable service) at a time slot. This is a real booking: Appointo may email the customer a confirmation and reserve the slot; the booking can later be cancelled with appointo_cancel_booking. Check appointo_get_availability first. Not idempotent: calling twice creates two bookings. The docs cap this at 100 requests per day.
Reschedule bookingappointo_reschedule_booking
WRITE: move a booking (or only some of its customers) to a new time slot. Appointo may notify the customers of the change. override=true forces the booking into the slot even if it is unavailable or full, so leave it off unless the user explicitly asked for it. The docs cap this at 100 requests per day.
Cancel bookingappointo_cancel_booking
WRITE: cancel a booking, or only some of its customers. The slot is freed and Appointo may notify the customers; whether a Shopify order is refunded is not controlled by this call. Cannot be undone through this server (create a new booking instead). The docs cap this at 100 requests per day.
Update booking buffer timesappointo_update_booking_buffers
WRITE: set the start and/or end buffer time (minutes blocked before/after) of one booking. At least one value is required. The docs cap this at 100 requests per day.

Your usefulapi plan · 4

Usage status (free-tier meter)appointo_usage_status
Report the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter.
Request a missing featureappointo_request_feature
Tell usefulapi that the user needs something the Appointo tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter.
Upgrade to Pro or Pro+appointo_upgrade
Get a paid plan for Appointo (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter.
Cancel the Pro subscriptionappointo_cancel_subscription
Cancel the caller's Appointo Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run appointo_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with Appointo in Claude or ChatGPT?

See upcoming or past bookings. Find open time slots for a service. Review cancelled bookings. Review recurring booking subscriptions. Book a customer into an open slot. Reschedule or cancel a booking, or set its buffer times. See what you can do for the details.

Is this an official Appointo product?

No. usefulapi is an independent service. It is not affiliated with or endorsed by Appointo. The server calls the Appointo API with your own Appointo access, so it sees only the data that your account can see.

Can I connect Appointo to Claude or ChatGPT?

Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.

What do I need to connect?

The login page asks for your Appointo API token. See Before you connect for where to find it.

Do I put my Appointo key or an Authorization header in the client config?

No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Appointo API token. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

How do you keep my Appointo credentials?

The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Appointo API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in Appointo.

Can the AI change my Appointo data?

Yes, if you approve it. 4 of the 10 Appointo tools can create or change data. The other 6 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.

What does it cost?

The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this Appointo server only. Cancel any time: your paid plan then runs to the end of the paid period. Run appointo_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run appointo_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run appointo_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a Appointo tool that I need is missing?

Tell the AI what you wanted to do. It can send the request with appointo_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.

Which AI clients can I use?

Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.

This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
