Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)

Contacts view or an explicit offset returns {appointments, pagination}; follow pagination.next
acuity_get_appointmentGet a single appointment by its id. Acuity REST: GET /appointments/{id}.
acuity_list_appointment_typesList the account's appointment types (services and classes), including price, duration and calendars. Acuity REST: GET /appointment-types.
acuity_list_calendarsList the account's calendars (staff/resources appointments can be booked on). Acuity REST: GET /calendars.
acuity_availability_datesList dates in a month that have availability for an appointment type. Acuity REST: GET /availability/dates.
acuity_availability_timesList available time slots on a given date for an appointment type. Acuity REST: GET /availability/times.
acuity_availability_classesList group class time slots (for class-type appointment types) in a month. Acuity REST: GET /availability/classes.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
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.
The registry does not list a required key, though some servers ask you to sign in on first use.
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.
The GitHub repo last changed –, and the latest version (1.36.3) reached the registry yesterday.
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.

Manage Acuity Scheduling from Claude, Cursor, or any MCP client — read appointments, appointment types, calendars and availability, and create, cancel or reschedule bookings. Hosted, no local install: connect with your Acuity credentials.
Live endpoint: https://acuity-scheduling.usefulapi.io/mcp · Homepage: https://usefulapi.io
https://acuity-scheduling.usefulapi.io/mcp.claude mcp add --transport http acuity-scheduling https://acuity-scheduling.usefulapi.io/mcp, then run /mcp to log in.{

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 Acuity Scheduling credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/acuity-scheduling/
On first connect you'll provide your Acuity User ID and API Key (Acuity → Integrations → API). They're validated, stored per-user, and scoped to you — no keys in config files.
