README

MCP server that orchestrates Java JDK 6/8 → 21 migrations with human-in-the-loop approval gates.

What it does

Scans your Java project and identifies all incompatibilities with JDK 21
Generates a phased migration plan (6 phases) with risk classification
Guides each phase with automated analysis and manual review gates
Tracks approvals, generates an HTML audit report

Requirements

Node.js >= 20
Java project using Maven or Gradle
Git available in PATH

Installation

Claude Code (recommended)

Add to your ~/.claude/settings.json:

{
  "mcpServers": {
    "jdk-migration": {
      "command": "npx",
      "args": ["-y", "jdk-migration-mcp"]
    }
  }
}

Or install globally:

npm install -g jdk-migration-mcp

Then configure:

{
  "mcpServers": {
    "jdk-migration": {
      "command": "jdk-migration-mcp"
    }
  }
}

Usage

With the MCP active in Claude Code, use natural language:

Execute a descoberta do projeto neste diretório.
Construa o plano de migração.
Aprovar gate 0 como <Seu Nome>.
Executar fase 1.
