Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Check shifts, time clock entries, time-off requests, swaps and availability, and manage shifts.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.
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.
wheniwork_get_accountFetch the When I Work account (workplace) the token acts on — company name, plan and settings; for a parent account also its child accounts. A cheap way to confirm the credentials work. When I Work: GET /2/account.
wheniwork_list_usersList the employees, supervisors, managers and admins in the account, optionally limited to some schedules or searched by name/email. Role codes: 1 admin, 2 manager, 3 employee, 5 supervisor. When I Work: GET /2/users.
wheniwork_get_userFetch one user by id — name, email, role, positions, schedules, wage. When I Work: GET /2/users/{id}.
wheniwork_list_locationsList the schedules in the account. The API calls a schedule a "location"; its id is the location_id every shift belongs to. When I Work: GET /2/locations.
wheniwork_list_positionsList the positions (job roles such as Cashier or Dishwasher) in the account. When I Work: GET /2/positions.
wheniwork_list_shiftsList scheduled shifts in a time window — who works when, where and in which position — optionally including open shifts and unpublished drafts. Answers "who is on on Friday?" and "what open shifts are left?". When I Work: GET /2/shifts.
wheniwork_get_shiftFetch one shift by id, including its breaks and publish state. When I Work: GET /2/shifts/{id}.
wheniwork_list_eligible_users_for_shiftFind who could take an open shift — either an existing shift (shift_id) or a hypothetical one (start, end, position_id and location_id all required). When I Work: GET /2/shifts/eligible.
wheniwork_list_timesList clocked time entries — actual hours worked, clock-in/out times, length and approval state. Use only_open to see who is clocked in right now. When I Work: GET /2/times.
wheniwork_list_time_off_requestsList time-off requests in a date range, with the requesting users. Status: 0 pending, 1 canceled, 2 accepted, 3 expired, 4 denied. When I Work: GET /2/requests.
wheniwork_get_time_off_requestFetch one time-off request by id, with its message thread and users. When I Work: GET /2/requests/{request_id}.
wheniwork_list_time_off_typesList the time-off types (e.g. Personal, Sick, Holiday) and whether each allows paid time. Their ids are the type_id for a new request. When I Work: GET /2/requesttypes.
wheniwork_list_shift_swapsList shift requests: swaps, drops and alerts, with the shifts and users involved. Status: 0 pending, 1 approved, 2 declined, 3 completed, 4 canceled, 5 expired. Type: 1 swap, 2 drop, 3 alert. start and end must be given together. When I Work: GET /2/swaps.
wheniwork_list_availabilityList availability events — when people said they can or cannot work, including recurring patterns that fall in the window. Defaults to the caller, from now to two weeks out. When I Work: GET /2/availabilityevents.
wheniwork_list_annotationsList schedule annotations — announcements, business-closed days and blackout dates when time off is not allowed. Defaults to today through one year out. When I Work: GET /2/annotations.
wheniwork_create_shiftCreate one shift on a schedule — assigned to a user, or open (user_id 0). Created as a draft unless published is true. Undo by editing it or unpublishing. When I Work: POST /2/shifts.
wheniwork_update_shiftChange a shift — reassign it, move it, change position or notes. When I Work requires start_time, end_time and location_id on every update, so fetch the shift first and pass them back. This tool never sends a breaks array; When I Work documents that breaks omitted from an update'
wheniwork_publish_shiftsPublish draft shifts so employees can see them. Publishing does not itself send notifications. Undo with wheniwork_unpublish_shifts. When I Work: POST /2/shifts/publish.
wheniwork_unpublish_shiftsReturn published shifts to draft, hiding them from employees. Undo with wheniwork_publish_shifts. When I Work: POST /2/shifts/unpublish.
wheniwork_create_time_off_requestCreate a time-off request for a user (default the calling user). It starts pending; cancel it with wheniwork_update_time_off_request (status 1). Get type ids from wheniwork_list_time_off_types. When I Work: POST /2/requests.
wheniwork_update_time_off_requestChange a time-off request: set its status (0 pending, 1 canceled, 2 accepted/approved, 3 expired, 4 denied) and/or its dates or hours. Reversible — set the status back. start_time and end_time must be given together. When I Work: PUT /2/requests/{request_id}.

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.

On first connect you'll provide your When I Work developer key (W-Key), email and password, plus an optional workplace user id. They're validated, stored per-user, and scoped to you — no keys in config files.
