Overview

Description from the maker (original English)

Read Appointo bookings, availability and subscriptions; create, reschedule and cancel bookings.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 3 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • Can do 10 things (tools) appointo_list_products, appointo_list_appointments, appointo_get_availability, appointo_list_bookings …
  • The registry lists no key to fill in.

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "appointo": {

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save
  4. If it asks you to sign in, sign in with the maker

What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

  • appointo_list_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

    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

    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

    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

    List cancelled bookings, same shape as appointo_list_bookings. GET /bookings/cancelled_bookings.

  • appointo_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 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_availabilit

  • appointo_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

  • appointo_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 reque

  • appointo_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. PUT /bookings/{booking_id}.

Common questions

Is Appointo MCP by usefulapi safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.16.3) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, Recta

Appointo MCP by usefulapi

Read Appointo bookings, availability and subscriptions; create, reschedule and cancel bookings.

Live endpoint: https://appointo.usefulapi.io/mcp · Homepage: https://usefulapi.io/appointo

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://appointo.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http appointo https://appointo.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
{

"mcpServers": { "appointo": { "url": "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, and the login page asks for your Appointo credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/appointo/

On first connect you'll paste your Appointo API token (the Appointo app → Plans & Settings; paid plan).
