clouvel 5.0.0

MCP server that remembers AI mistakes and prevents regressions - AI makes it fast, Clouvel makes it right

Clouvel

Stop Claude Code from breaking your code.

Claude Code is fast. But it forgets what it broke yesterday and breaks it again today.

Clouvel remembers. It records every error, warns before repeats, and blocks coding without a spec.

---

The Problem

What happens	Why it hurts
AI recreates a bug it fixed yesterday	No error memory between sessions
You ship without anyone reviewing	No second pair of eyes
"Why did we do it this way?"	Decisions lost when context resets
New session = same old mistakes	AI starts from zero every time

What Clouvel Does

1. Error Memory — AI that learns from mistakes

AI:  Warning: This error happened before.
     Root cause: Missing null check on DB query result
     Prevention: Always validate query results before accessing
     (Memory #7 — prevented this bug 3 times)

2. Spec Gate — Think before AI codes

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

You: *writes PRD*
AI:  PASS - Ready to code.

3. Quick Check — Blind spots in 10 seconds

PM:  "What happens when login fails 5 times?"
CTO: "Rate limiting needed for brute force protection."

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 configuration

Windows:

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

Mac/Linux:

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

How It Works

Day 1:  Install → start → write PRD → can_code PASS → code
Day 3:  Error happens → error_record saves it
Day 5:  Same file → error_check warns "this broke before"
Day 7:  5+ errors → "Full history available in Pro"
Day 10: Context runs out → context_save/load preserves everything
Day 14: Decide: $7.99/mo or stay Free
