Read Appointo bookings, availability and subscriptions; create, reschedule and cancel bookings. Hosted by usefulapi — connect from Claude, ChatGPT, Cursor, or any MCP client.
Team and Enterprise: an Owner adds the connector for the organization first.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"appointo": {
"url": "https://appointo.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"appointo": {
"type": "http",
"url": "https://appointo.usefulapi.io/mcp"
}
}
}No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run these commands. The second one opens the login page:
Other MCP clients (Windsurf, Cline, Zed and more): add the URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser. Do not add an Authorization header: see 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.
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.
Turn on the Appointo connector, then ask in plain words. The AI picks the tools.
| Tool | Type | What it does |
|---|---|---|
appointo_list_products | read | List bookable products List the Shopify products that are set up as bookable in Appointo: name, appointment type, whether the widget is shown, and each product's appointments (the bookable variants/services with price, currency and id). Use an appointment id for availability and bookings. GET /products. |
appointo_list_appointments | read | List appointments (bookable services) 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). GET /appointments. |
appointo_get_availability | read | Get appointment availability The free time slots of one appointment (bookable service) from start_date, optionally to end_date. Use it before creating or rescheduling a booking. GET /appointments/{appointment_id}/calendar_availability. |
appointo_list_bookings | read | List bookings List bookings with time, product, duration, quantity, price and the customers (name, email, phone, address). Filter upcoming/past or search; pass booking_id for one booking. The customers' cancel/reschedule link ids are never returned. GET /bookings. |
appointo_list_cancelled_bookings | read | List cancelled bookings List cancelled bookings, same shape as appointo_list_bookings. GET /bookings/cancelled_bookings. |
appointo_list_subscription_contracts | read | List subscription contracts List the recurring booking subscription contracts (customers who subscribed to repeat appointments). Search by product, variant, order number or customer name. The API documents no paging for this list. GET /appointment_subscriptions. |
appointo_create_booking | write | 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. POST /bookings. |
appointo_reschedule_booking | write | 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. PUT /bookings/reschedule. |
appointo_cancel_booking | write | 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. PUT /bookings/cancel. |
appointo_update_booking_buffers | write | Update booking buffer times 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. PUT /bookings/{booking_id}. |
appointo_usage_status | Usage status (free-tier meter) 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. | |
appointo_request_feature | Request a missing 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. | |
appointo_upgrade | Upgrade to Pro (unlimited*) Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on Appointo (the free tier caps monthly usage). Plans: "monthly" — $9/month; "yearly" — $90/year (2 months free). Cancel any time: Pro then runs to the end of the paid period, so it also suits a one-time job. *A fair use limit applies. For heavy use (near Pro's limit): "plus" or "plus_yearly" — Pro+, $19/month or $190/year, unlimited tool calls (fair use limit: 100,000 a month); an existing Pro subscription changes to Pro+ in place (needs confirm: true; the price difference for the rest of the period is charged at once). Otherwise returns a short link to open in your browser (it opens Stripe Checkout); after payment the account upgrades automatically. Does not count against the meter. | |
appointo_cancel_subscription | Cancel the Pro 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. |
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper user | $9/mo · $90/yr | Unlimited* |
*Pro fair use limit: 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this Appointo server only. Subscribe with appointo_upgrade (it returns a Stripe Checkout link). Cancel any time with appointo_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running appointo_upgrade before then undoes the cancel. Or write to [email protected].
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.
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.
The login page asks for your Appointo API token. See Before you connect for where to find it.
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.
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.
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.
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls (fair use limit: 10,000 tool calls a month), for this Appointo server only. Cancel any time: Pro then runs to the end of the paid period. Run appointo_usage_status to see how many calls you used.
Ask the AI to run appointo_upgrade: it returns a Stripe Checkout link. To cancel, run appointo_cancel_subscription. Pro continues to the end of the paid period.
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.
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.
