Yesterdays Number
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.

Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"yesterdays-number": {
"url": "https://gateway.pipeworx.io/yesterdays-number/mcp"
}
}
}
What this endpoint actually serves
tools/list at https://gateway.pipeworx.io/yesterdays-number/mcp returns the tools in the table
above plus the shared Pipeworx meta-tools — ask_pipeworx,
discover_tools, search_within, remember/recall and the rest of the
gateway-wide set. So the tool count you see is larger than this table: a
single-pack endpoint currently lists roughly 30 shared tools alongside the
pack's own. The connection's initialize response states its exact scope, and
is the authoritative answer for a given day.
