바이브코딩 프로세스를 강제하는 MCP 서버 - PRD 없으면 코딩 없다

Project description

Clouvel

No spec, no code. PRD-First gate for AI coding.

PyPI Python License

Demo


The Problem

You ask AI to "build login" and it:

  • Skips password reset
  • Forgets social auth
  • Ignores error handling
  • Builds something different every time

Result: Hours of debugging "almost right" code.

The Solution

Clouvel blocks AI coding until you write a spec (PRD).

You: "Build login"
AI:  ❌ BLOCKED - No PRD found. Write a spec first.

You: *writes PRD with requirements*
AI:  ✅ PASS - PRD found. Coding allowed.

Same input → Same output. Every time.


Quick Start

# Install
pip install clouvel

# Add to Claude Code (auto-detects your platform)
clouvel install

# Start coding - can_code check runs automatically
claude

That's it. No config needed.


How It Works

  1. You ask AI to code something
  2. Clouvel checks for PRD (Product Requirements Document)
  3. No PRD? Blocked. Write the spec first.
  4. PRD exists? Allowed. AI codes with clear requirements.

Before & After

Without Clouvel With Clouvel
"Build login" → AI guesses "Build login" → AI reads PRD
Missing features All requirements included
Different results each time Consistent output
Debug for hours Works as specified

Installation

Requirements

  • Python 3.10+
  • Claude Code, Claude Desktop, or VS Code with Claude extension

Install

pip install clouvel

Connect to Claude

Automatic (recommended):

clouvel install

Manual - Windows:

{
  "mcpServers": {
    "clouvel": {
      "command": "py",
      "args": ["-m", "clouvel.server"]
    }
  }
}

Manual - Mac/Linux:

{
  "mcpServers": {
    "clouvel": {
      "command": "python3",
      "args": ["-m", "clouvel.server"]
    }
  }
}

Usage Examples

Block coding without PRD

You: "Build a user authentication system"

Clouvel: ❌ BLOCKED
- PRD.md not found
- Architecture.md not found

💡 Write a PRD first. Use `start` to begin.

Start a new project

You: "Start a new project"

Clouvel: 🚀 Project detected: web-app

Questions:
1. What's the main goal?
2. Who are the users?
3. What are the core features?

→ Generates PRD from your answers

Get manager feedback (Pro)

You: "Review my login implementation"

👔 PM: User story covers happy path, but what about failed attempts?
🛠️ CTO: Consider rate limiting for brute force protection.
🧪 QA: Need tests for edge cases - empty password, SQL injection.
🔒 CSO: ⚠️ CRITICAL - Password hashing not implemented.

Status: NEEDS_REVISION
