Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Read absences, time entries and balances; run the time clock and request absences in Timebutler.
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.
timebutler_get_profileGet the profile of the user behind the token: id, name, email, role (USER, MANAGER or ADMIN), department, branch office, and whether business trips and time tracking are enabled. Timebutler API: GET /user/profile.
timebutler_list_employeesList the employees the caller can see (manager or admin only), with ids, names, role, department, manager ids and active flag. Use the ids in other tools. Timebutler API: GET /employees.
timebutler_list_absence_typesList the absence types the company configured (vacation, sickness and others), with whether each needs approval, a medical certificate, or allows half days. Use the id in timebutler_create_absence_request. Timebutler API: GET /absence-types.
timebutler_list_categoriesList the time-tracking categories and the default category id. Use an id in the clock and time-entry tools. Timebutler API: GET /categories.
timebutler_list_projectsList the time-tracking projects, the default project id, and whether a project is mandatory. Use an id in the clock and time-entry tools. Timebutler API: GET /projects.
timebutler_list_my_absence_requestsList the caller's own absence requests with dates, days or hours, half-day setting, and status (pending, approved or rejected). Timebutler API: GET /absence-requests/my.
timebutler_list_team_absence_requestsList absence requests of the employees the caller manages (manager or admin only). Shows status and employee names. Timebutler API: GET /absence-requests/team.
timebutler_get_absence_pending_countCount the open absence requests and open cancellation requests for the caller's team (manager or admin only). Timebutler API: GET /absence-requests/pending-count.
timebutler_list_my_time_entriesList the caller's recorded time entries, sorted by date and start time. Without year and month it returns the current month; year alone returns a whole year. Optional filters: project, category and status. Timebutler API: GET /time-entries/my.
timebutler_get_time_entry_pending_countCount the time entries of the caller's team that wait for approval (manager or admin only). Timebutler API: GET /time-entries/pending-count.
timebutler_list_time_entry_requestsList the pending time entry requests of the caller's team with date, start and end time, worked minutes, project and remarks (manager or admin only). Timebutler API: GET /time-entry-requests.
timebutler_get_time_clock_statusGet the caller's time clock state: idle, running, paused or waiting, with the start time, elapsed work seconds and break seconds. Timebutler API: GET /time-clock/status.
timebutler_get_work_summaryGet today's working-time summary for the caller: commitment, worked, remaining minutes, percent done and break minutes. Timebutler API: GET /time-tracking/work-summary.
timebutler_get_time_off_summaryGet the caller's vacation and sickness balance: vacation days total, remaining, approved and pending, and illness days taken. Timebutler API: GET /time-tracking/time-off-summary.
timebutler_clock_startStart the caller's time clock. Fails with HTTP 409 when the clock already runs. The clock can enter the waiting state first if the company sets a minimum start interval. Timebutler API: POST /time-clock/start.
timebutler_clock_pausePause the running time clock of the caller (starts a break). Timebutler API: POST /time-clock/pause.
timebutler_clock_resumeResume the paused time clock of the caller (ends the break). Timebutler API: POST /time-clock/resume.
timebutler_clock_stopStop the running or paused time clock and save the resulting time entry. Optional project id, category id and remarks. A waiting clock is discarded (HTTP 204). Timebutler API: POST /time-clock/stop.
timebutler_submit_clock_entryCreate a finished time entry from a start and end time on the same calendar day. Timestamps are Unix milliseconds. If the company needs manager approval, the entry starts as pending. Timebutler API: POST /time-tracking/clock-entry.
timebutler_create_absence_requestSubmit an absence or vacation request for the caller. The status is pending when the absence type needs manager approval, otherwise approved. Timebutler API: POST /absence-requests.

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.

Use your Timebutler account from Claude, Cursor, or any MCP client. It reads absences, time entries, time-off balances and, for managers, team requests, and it can run the time clock and request absences. Hosted, no local install: connect with your own credentials.

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 Timebutler credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/timebutler/
On first connect you provide a Timebutler personal access token (it starts with tb_; create it in your Timebutler account settings under personal access tokens). The server validates it and stores it per user. No keys go in config files.
