Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Employee leave and PTO: requests, approvals, balances, who is out, and conflict checks.
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.

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.
leave_employee_addAdd an employee to the leave tracker and return their EMP-NNNN id. Give their annual paid-leave allowance in whole days and any days carried over from last year. Balances charge approved plus pending leave against allowance + carried-over. Free tier: unlimited.
leave_requestCreate a leave or PTO request and return its LV-NNNN id. type is vacation, sick, unpaid or parental. start and end are inclusive YYYY-MM-DD dates; halfDay charges half a day for the whole span. A pending request is refussed if it would overlap another approved or pending request
leave_approveApprove a pending leave request by id. Also used to re-open a rejected one. Nothing to approve on an already-approved request.
leave_rejectReject or cancel a leave request by id. A pending or approved request becomes rejected; a rejected one can be reopened via leave_approve. Use leave_cancel (via reject with reason) for voluntary withdrawal.
leave_balanceShow one employee's leave balance: allowance + carried-over, minus approved and pending, as whole days plus a possible half day. Remaining is rounded down to whole days on the report.
leave_out_rangeWho is out in a date range: start and end are inclusive YYYY-MM-DD. Each employee appears once per day; pending requests count as a plan. Use for coverage, calendars and absence summaries. Free tier: unlimited.
leave_listList all employees, or all leave requests (optionally filtered by employee and/or status). Omit the filter to list requests.
leave_importPro. Bulk-create leave requests from a CSV/TSV. First row is a header: employee,type,start,end,halfDay,status,reason. status may be omitted (defaults to pending) or be approved/rejected. Each request is still checked for overlap conflicts; a conflicting row is reported, not appli
leave_export_icsPro. Export all APPROVED leave as an .ics calendar (RFC5545). Returns the calendar text; pass path to also write it to a local file. watermark-free.
license_statusReport this endpoint's licence state for your token as JSON: the product, the tier free or pro, why it is not Pro, and the checkout URL. Call it to explain a free-tier refusal. No arguments, nothing changes.
license_activateTurn Pro on for this connection with key, an MCPL1. . issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.
leave_cancelCancel a pending or approved request by id, keeping its record with status cancelled. Differs from leave_reject in intent (voluntary withdrawal). Nothing happened if already cancelled.

In the [official MCP Registry](https://registry.modelcontextprotocol.io/v0.1/servers/io.github.theluckystrike%2Fleave/versions/latest) (io.github.theluckystrike/leave). Employee leave/PTO tracking for solopreneurs and small studios: who is off, when, and how many days each person has left. Add employees with an annual allowance and any carried-over days, log vacation/sick/personal requests (including half-days), approve or reject them, and read balances, conflicts and who-is-out calendars directly from your MCP client - Claude Desktop, Cursor, or any MCP host.
"leave_employee_add" - add an employee with annualAllowance (and optional carriedOver)."leave_request" - log a leave request (employee, type, start, end, optional halfDay, reason)."leave_approve" / "leave_reject" - decide a request; decisions are recorded with dates."leave_cancel" - cancel a pending or approved request (keeps the audit trail)."leave_balance" - allowance, carried, approved, pending, committed and remaining days per employee."leave_out_range" - who is out in a date range: day-by-day calendar rows plus person-days."leave_list" - all employees and requests, filterable by employee and status."leave_import" (Pro) - bulk-create requests from CSV; conflicting rows are rejected one by one, valid rows still apply."leave_export_ics" (Pro) - export approved leave as an RFC5545 .ics calendar.A day is committed when the request that spends it is approved or pending. Balance is allowance + carried − approved − pending. Cancelling returns the days immediately; rejecting never charged them.
Overlapping requests for the same person are refused at creation time - both pending and approved count - so the calendar never contains two requests claiming the same day.
The free tier is the full CRUD surface: employees, requests, approvals, balances, calendars - watermark-free, no request limits. Pro (an MCP_LICENSE_KEY, activate with "license_activate") adds bulk CSV import and ICS calendar export. Run "license_status" to see the current tier.

Data lives in a single JSON store (~/.mcp-leave/store.json, or $XDG_DATA_HOME/mcp-servers/leave/store.json when set), written atomically under a file lock, so two clients on one machine never interleave writes.
