How to integrate Nager.Date using MCP

Look up public holidays worldwide. This guide creates an MCP server from Arthur's Nager.Date template — tools preconfigured against https://date.nager.at/api/v3 — and finishes by sharing the server's MCP swagger documentation.

Steps

1. Go to the REST API Templates gallery and search for Nager.Date.

   

   

2. Click Use template on the Nager.Date card to open the server-creation dialog.

   

3. Review the server name — the dialog lists every tool that will be created.

   

4. Click Create server. Arthur creates the server, applies the authentication, and generates all the tools.

   

5. Open the server's Tools tab to review the generated tools.

   

6. Open the server's Connect section and click Share the MCP swagger documentation — Arthur generates the public documentation link and QR code for this server.

   

   

   

Confirm it worked

The server appears with 3 preconfigured tool(s): list_public_holidays, list_next_public_holidays, list_available_countries. The Connect section offers the MCP swagger documentation — a shareable page with setup instructions for any AI client.

Good to know

• List public holidays for a country and year, get the next upcoming public holidays for a country, and list supported countries.
• No authentication required — the server is ready to use immediately.
• Official API documentation: https://date.nager.at/Api
• Editing a tool later never changes the template — templates are starting points, and the server is fully yours after creation.
