Overview

AI-generated overview

Remote MCP server for Türkiye's public holidays and business-day math, letting an assistant list holidays and add or count working days from 2022 to 2035.

What you can do
  • List a year's public holidays with Turkish and English names, type, half-day eves and announced administrative leave
  • Check whether a given date is a business day, which holiday falls on it, and whether only the afternoon is off
  • Add or subtract N business days from a start date, for payment terms or legal deadlines
  • Count the business days between two dates, with both dates included
When to use it
Useful when scheduling or calculating deadlines, payment terms or delivery dates that depend on Turkish working days, or when you need to know whether a specific date is a holiday in Türkiye.
Requirements
A remote streamable HTTP endpoint; no package, account, API key or header is declared.
Before you install
The calendar is limited to 2022-01-01 through 2035-12-31, and religious holiday dates follow Diyanet's announced calendar, so results outside that range or for later changes may not apply.

Installation

In SourceWeft

  1. Open Türkiye Business Days & Public Holidays in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.foster-ops%2Fturkey-business-calendar/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
