Key Capabilities
Stream YC Startup Prover audits via Vercel AI SDK
Most founders build solutions nobody asked for. You can wire this MCP server directly into your Next.js frontend to evaluate business plans as they get typed. The `validate_yc_startup` tool catches solution-seeking behavior instantly, flagging pitches that focus on proprietary algorithms instead of actual user pain points. Users watch the critique generate live on the screen instead of waiting for a loading spinner. Your React application pipes the founder's input through the Vercel AI SDK, applying Paul Graham's strict criteria for unscalable beginnings and real metric discipline on the fly.
Reject vanity metrics in real-time
Celebrating Instagram followers kills early-stage companies. Your agent evaluates the provided data to demand weekly retention curves and monthly recurring revenue numbers. If a founder boasts about free downloads, the system pushes back and asks for default alive or dead calculations. Edge functions handle these evaluations without blocking your main UI thread. You build interfaces that force entrepreneurs to define their one core value proposition in a single sentence before the form even submits.
Validate customer conversations
Ivory tower development leads to dead products. The integration checks how many actual user conversations happened this week and what changed because of them. Founders can't fake this validation because the logic requires specific names, exact current solutions, and quantified willingness to pay. Streaming text components render these harsh reality checks line by line. Your application acts as an automated YC partner, demanding proof of manual onboarding and high-touch support before validating any scaling plans.
