Yc Rejection

pipeworx-io/mcp-yc-rejection

Wraps the StupidAPIs YC rejection generator, which takes any startup idea and returns an instant rejection letter in the style of Y Combinator. There's exactly one tool: yc_rejection_generate. The encouragement is explicitly insincere. Part of the Pipeworx gateway ecosystem, so you can either connect to this specific endpoint or access it through the full Pipeworx gateway alongside 250+ other data sources. Requires an X-API-Key to authenticate. Useful if you're building a startup humor bot, need programmatic rejection letter generation for testing UI flows, or just want to roast business ideas on demand. Uses streamable HTTP transport.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "yc-rejection": {
      "url": "https://gateway.pipeworx.io/yc-rejection/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/yc-rejection/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.
