Summary
Wraps StupidAPIs' yesterdays-number endpoint, which returns a random number that's been "aged" 24 hours. You get exactly one tool, yesterdays_number_get, that fetches this pre-generated random value. Requires an X-API-Key for authentication. The joke here is in the premise: some numbers supposedly get better with time, like wine. This is part of the Pipeworx gateway ecosystem, so you can either connect to this specific endpoint or access it through their full gateway alongside 673+ other data sources. If you need a random number with a sense of humor baked in, or you're exploring novelty APIs, this fits the bill.

Tools
| Tool | Description |
|---|---|
yesterdays_number_get | A random number, aged 24 hours for smoothness. Some numbers are better with time. This one is fine. |
Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"yesterdays-number": {
"url": "https://gateway.pipeworx.io/yesterdays-number/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 Yesterdays Number data" })
The gateway picks the right tool and fills the arguments automatically.
