Summary
Wraps the byabbe.se/on-this-day API to surface historical events, births, deaths, and other notable occurrences tied to specific dates. No authentication required. The source doesn't list specific tools, but this is part of the Pipeworx gateway ecosystem, which means you can query it through their ask_pipeworx natural language interface instead of calling tools directly. Reach for this when you're building conversational agents that need historical context, trivia features, or date-aware content generation. Works through streamable HTTP transport, so you can drop the gateway URL into any MCP client config and start querying immediately.
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": {
"onthisday": {
"url": "https://gateway.pipeworx.io/onthisday/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 Onthisday data" })
The gateway picks the right tool and fills the arguments automatically.
