Summary
Wraps the Nager.Date API to give Claude access to public holiday data across countries without requiring authentication. This is the kind of server you'd reach for when building scheduling tools, calendar features, or any application that needs to be aware of regional holidays. Pipeworx hosts it as part of their larger gateway offering (673+ data sources), but you can connect to just the holidays endpoint if that's all you need. The implementation uses streamable HTTP transport and offers a plain English query interface through ask_pipeworx alongside direct tool calls. Free to use, MIT licensed.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.

Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"holidays": {
"url": "https://gateway.pipeworx.io/holidays/mcp"
}
}
}
Or connect to the full Pipeworx gateway for access to all 673+ data sources:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Using with ask_pipeworx
Instead of calling tools directly, you can ask questions in plain English:
ask_pipeworx({ question: "your question about Holidays data" })
The gateway picks the right tool and fills the arguments automatically.
