Connects Claude to holiday data through the OpenHolidays API via the Pipeworx gateway. The source doesn't list specific tools, but given the name, you'd expect operations for querying public holidays by country, region, or date range. Useful when you need to factor holidays into scheduling, calculate business days, or understand regional observances without hardcoding calendar data. Part of Pipeworx's larger gateway that bundles 851+ data sources, so you can add just this endpoint or connect to the full suite. Includes an ask_pipeworx natural language interface that routes questions to the right tools automatically instead of calling them directly.
OpenHolidays MCP.
Part of Pipeworx — an MCP gateway connecting AI agents to 851+ live data sources.
| Tool | Description |
|---|
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"openholidays": {
"url": "https://gateway.pipeworx.io/openholidays/mcp"
}
}
}
Or connect to the full Pipeworx gateway for access to all 851+ data sources:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Instead of calling tools directly, you can ask questions in plain English:
ask_pipeworx({ question: "your question about Openholidays data" })
The gateway picks the right tool and fills the arguments automatically.
