Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 12

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

leave
leave_approve
Approve a pending leave request by id. Also used to re-open a rejected one. Nothing to approve on an already-approved request.
leave_balance
Show 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_cancel
Cancel 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.
leave_employee_add
Add 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_export_ics
Pro. 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.
leave_import
Pro. 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 applied. watermark-free, full CRUD.
leave_list
List all employees, or all leave requests (optionally filtered by employee and/or status). Omit the filter to list requests.
leave_out_range
Who 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_reject
Reject 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_request
Create 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 of the same employee. Free tier: unlimited requests.
license
license_activate
Turn Pro on for this connection with key, an MCPL1.<payload>.<signature> 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.
license_status
Report 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.

McpStamp Leave Tracker — questions

Answers built from our own checks of this server.

What can McpStamp Leave Tracker do?
It exposes 12 tools, read directly from the server on our last check. Among them: leave_approve, leave_balance, leave_cancel, leave_employee_add, leave_export_ics, leave_import and 6 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
What is McpStamp Leave Tracker mostly used for?
Its tools cluster around leave and license. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is McpStamp Leave Tracker working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 181 ms. The bar chart above shows every period we have measured.
How do I connect McpStamp Leave Tracker?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does McpStamp Leave Tracker need an API key?
No. McpStamp Leave Tracker completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 12 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is McpStamp Leave Tracker?
It answers our handshake in 181 ms on average, which is faster than 72% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is McpStamp Leave Tracker open source?
The code is open source: it is published under the MIT licence, written in JavaScript, 2 stars on GitHub and 1 open issue. The licence covers the code in the repository, not the hosted service at mcp.zovo.one, which runs on its operator's own terms.
