Deadlines, billing periods and delivery estimates all break on public holidays in a country you do not live in. Asking for the working-day count directly is the difference between a date that holds and one that quietly slips.
A remote public-holiday server at https://inday.co/api/mcp over Streamable HTTP. It checks whether a date is a public holiday in a country, returns a full year's calendar, lists the countries covered, finds the next upcoming holiday, and counts working days between two dates.
- A specific date checked against a country's public holidays
- A full year holiday calendar for a country
- The 30+ supported countries listed
- The next upcoming holiday in a country
- Working days counted between two dates
A free API key from inday.co/signup, sent as the X-API-KEY header — the free tier is 1,000 requests a month with no card. The client connects over Streamable HTTP, or installs it in one click through Smithery; there is nothing to run locally.
One command plus a key — npx -y mcp-remote https://inday.co/api/mcp, then supply credentials
