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.

What it does

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.

Key Features

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

Tools Available

`start_project_planning()`

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?

`recommend_stack(session_requirements?)`

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

`explain_recommendation(detail_level?)`

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

`get_deployment_guide(platform?)`

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

Architecture

The server uses:

FastMCP: High-level Python framework for MCP servers
Elicitation Spec: Latest MCP elicitation specification for interactive questioning
Rule-based recommendations: Analyzes requirements to suggest appropriate technologies
Progressive disclosure: Builds complexity gradually based on user comfort level

Supported Platforms

The server focuses on Platform-as-a-Service solutions:

Frontend: Vercel, Netlify, GitHub Pages
Backend: Vercel Functions, Netlify Functions, Supabase
Database: Supabase, PlanetScale, Firebase
Auth: Supabase Auth, Auth0, Clerk
Hosting: Vercel, Netlify, Render

Development

To extend or modify the server:

Add new question types: Modify the elicitation flow in _ask_about_* functions
Enhance recommendations: Update the _analyze_requirements function
Add new platforms: Extend the recommendation logic and deployment guides
Improve UI: The elicitation spec supports rich form controls

Copy & paste — that's it

uv pip install fastmcp

Installation

Install dependencies:

uv pip install fastmcp

Run the server:

python run_server.py

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"]
    }
  }
}

Example Usage

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.
