Vibe Stack MCP

A Model Context Protocol (MCP) server that helps VibeCoder developers choose the perfect tech stack for their projects through progressive questioning and personalized recommendations.

Perfect for rapid prototyping and getting tech stack recommendations based on your project requirements, budget, timeline, and technical comfort level.

This MCP server helps developers quickly choose optimal technology stacks without getting bogged down in technical analysis paralysis. Instead of researching dozens of frameworks, it asks smart questions about your project and gives you the modern, battle-tested stack that fits your needs.

- Jargon-free questioning: Uses simple language anyone can understand
- Progressive elicitation: Gathers requirements step-by-step using MCP's elicitation spec
- Platform-as-a-Service focus: Recommends easy-to-use platforms like Vercel, Supabase, Netlify
- Practical guidance: Provides deployment guides and cost estimates
- Beginner-friendly: Focuses on tools that minimize technical complexity
- Add to your MCP client configuration(e.g., Claude Desktop):

{ "mcpServers": { "vibe-stack-planner": { "command": "python", "args": ["/path/to/vibe_coder_stack_planner/run_server.py"] } } }

Initiates the interactive planning process through a series of simple questions:

- What are you trying to build?
- Who will use it and how?
- What features do you need?
- How many users do you expect?
- What's your budget and technical comfort level?

Provides tech stack recommendations based on gathered requirements. Can be used with or without the interactive process.

Explains why specific technologies were recommended, with "basic" or "detailed" explanations.

Provides step-by-step deployment instructions tailored to your specific needs.

User: I want to build something but I don't know where to start technically. AI: Let me help you plan the right tech stack! I'll use the vibe coder stack planner to ask you some simple questions. [Uses start_project_planning tool] Server: Let's start planning your project! First, tell me about your vision. What problem are you trying to solve, or what idea do you want to build? [Progressive questioning continues...] Server: 🎉 Perfect! Based on what you've told me, here's my recommendation: Recommended Tech Stack: • Frontend: Next.js (React framework) for a modern web app • Backend: Supabase (handles database, auth, and API automatically) • Hosting: Vercel (free tier covers most small projects) • Domain: Namecheap or Google Domains (~$12/year) Why this works for you: I chose beginner-friendly tools that handle most technical details automatically. These tools let you build and deploy quickly. This stack has generous free tiers to keep costs minimal.
