🚀 Quick Start

Step-by-Step Docker Setup (Recommended)

1. Clone and Navigate

git clone https://github.com/TheAlchemist6/codecompass-mcp.git
cd codecompass-mcp

Expected output:

Cloning into 'codecompass-mcp'...
remote: Enumerating objects: 53, done.
remote: Total 53 (delta 0), reused 0 (delta 0), pack-reused 53
Receiving objects: 100% (53/53), 259.84 KiB | 1.85 MiB/s, done.

2. Configure Environment

cp .env.example .env
# Edit .env with your real API keys

MCP Client Integration

Claude Desktop Configuration

Add to your Claude Desktop configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "codecompass": {
      "command": "docker",
      "args": [
        "exec", "-i", "codecompass-mcp", 
        "node", "build/index.js"
      ],
