    Latest probe returned HTTP 200 in 149 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name when-i-work-mcp.

  • Pass
    Lists tools

    tools/list returned 21 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 149 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 149 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

    Free tier cited

    No publisher quote has been checked.

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    101 of 101 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Pass
    Source repo linked

    A repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass

Capabilities

Tools 21

wheniwork_create_shift

Create 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.

Discovered
wheniwork_create_time_off_request

Create 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.

Discovered
wheniwork_get_account

Fetch 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.

Discovered
wheniwork_get_shift

Fetch one shift by id, including its breaks and publish state. When I Work: GET /2/shifts/{id}.

Discovered
wheniwork_get_time_off_request

Fetch one time-off request by id, with its message thread and users. When I Work: GET /2/requests/{request_id}.

Discovered
wheniwork_get_user

Fetch one user by id — name, email, role, positions, schedules, wage. When I Work: GET /2/users/{id}.

Discovered
wheniwork_list_annotations

List 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.

Discovered
wheniwork_list_availability

List 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.

Discovered
wheniwork_list_eligible_users_for_shift

Find 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.

Discovered
wheniwork_list_locations

List 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.

Discovered
wheniwork_list_positions

List the positions (job roles such as Cashier or Dishwasher) in the account. When I Work: GET /2/positions.

Discovered
wheniwork_list_shift_swaps

List 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.

Discovered
wheniwork_list_shifts

List 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.

Discovered
wheniwork_list_time_off_requests

List 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.

Discovered
wheniwork_list_time_off_types

List 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.

Discovered
wheniwork_list_times

List 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.

Discovered
wheniwork_list_users

List 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.

Discovered
wheniwork_publish_shifts

Publish 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.

Discovered
wheniwork_unpublish_shifts

Return published shifts to draft, hiding them from employees. Undo with wheniwork_publish_shifts. When I Work: POST /2/shifts/unpublish.

Discovered
wheniwork_update_shift

Change 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's breaks list are removed, so re-check the shift's breaks afterwards. When I Work: PUT /2/shifts/{id}.

Discovered
wheniwork_update_time_off_request

Change 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}.
