바이브코딩 프로세스를 강제하는 MCP 서버 - PRD 없으면 코딩 없다
Project description
Clouvel
No spec, no code. PRD-First gate for AI coding.
v3.0 - FREE/PRO Tier Changes
| FREE (v3.0) | PRO | |
|---|---|---|
| Managers | 1 (PM only) | 8 (all) |
| can_code | WARN (doesn't block) | BLOCK |
| Projects | 1 | Unlimited |
Upgrade: pip install --upgrade clouvel
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
- You ask AI to code something
- Clouvel checks for PRD (Product Requirements Document)
- No PRD? Blocked. Write the spec first.
- 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

"clouvel": {
"command": "py",
"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.
