EUROPE-focused (~30 countries: DE, FR, NL, CH, IT, AT, BE, ES, PL, etc.). Returns each holiday with its localized name, dates, whether it is nationwide, and which subdivisions observe it. Keyless. For school terms/breaks use school_holidays instead. |\n| `school_holidays` | School holidays (term breaks: Christmas, Easter, summer, etc.) for a European country in a date range, optionally scoped to one subdivision. This is the unique value-add over worldwide public-holiday sources — school calendars vary by region. EUROPE-focused (~30 countries). Returns each break with its localized name, dates, and observing subdivisions. Keyless. |\n| `list_countries` | List the ~30 European countries OpenHolidays covers, with their ISO codes and official languages. EUROPE-focused. Keyless. |\n| `list_subdivisions` | List the regional subdivisions (federal states, regions, cantons, etc.) of a European country, with their codes and category. Use the returned codes to scope school_holidays. EUROPE-focused. Keyless. |\n\n## Quick Start\n\nAdd to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):\n\n```json\n{\n  \"mcpServers\": {\n    \"openholidays\": {\n      \"url\": \"https://gateway.pipeworx.io/openholidays/mcp\"\n    }\n  }\n}\n```\n\n### What this endpoint actually serves\n\n`tools/list` at `https://gateway.pipeworx.io/openholidays/mcp` returns the tools in the table\nabove **plus the shared Pipeworx meta-tools** — `ask_pipeworx`,\n`discover_tools`, `search_within`, `remember`/`recall` and the rest of the\ngateway-wide set. So the tool count you see is larger than this table: a\nsingle-pack endpoint currently lists roughly 30 shared tools alongside the\npack's own. The connection's `initialize` response states its exact scope, and\nis the authoritative answer for a given day.\n\nThis is deliberate, not multiplexing by accident. The meta-tools are what let a\nscoped connection answer a question this pack does not cover — via\n`ask_pipeworx`, which routes across the whole catalog — without you adding a\nsecond MCP server. There is currently no way to mount a pack endpoint without\nthem; if the extra schemas cost you more context than the routing is worth,\nconnect to the full gateway once rather than to several pack endpoints.\n\nOr connect to the full Pipeworx gateway to get every pack's tools listed\ndirectly, instead of just this one's:\n\n```json\n{\n  \"mcpServers\": {\n    \"pipeworx\": {\n      \"url\": \"https://gateway.pipeworx.io/mcp\"\n    }\n  }\n}\n```\n\nBoth URLs reach the same gateway and the same 1476+ data sources. The\nonly difference is which pack's tools are listed **directly**; `ask_pipeworx`\nreaches all of them from either one.\n\n## Using with ask_pipeworx\n\nInstead of calling tools directly, you can ask questions in plain English —\nthis works on the pack endpoint above as well as on the full gateway:\n\n```\nask_pipeworx({ question: \"your question about Openholidays data\" })\n```\n\nThe gateway picks the right tool and fills the arguments automatically.\n\n## More\n\n- [Docs and guides](https://pipeworx.io/docs)\n- [pipeworx.io](https://pipeworx.io)\n\n## License\n\nMIT\n",
