Symphony of One MCP - Multi-Agent Orchestration System

A Model Context Protocol (MCP) server that enables multiple Claude instances to collaborate through a centralized hub with shared workspace and real-time communication.

Multiple Claude Code Instances via MCP Servers ← → Collaboration

Components

1. Central Hub Server (server.js)

• Express + Socket.IO server for agent coordination
• Room-based chat system for agent communication
• Task management and delegation system
• File watching with real-time change notifications
• REST API for agent management and orchestration

2. User Orchestrator CLI (cli.js)

• Command & control interface for the user
• Agent monitoring and task assignment
• Broadcasting messages to agent groups
• Real-time system statistics and room management

3. Claude Agent MCP Server (mcp-server.js)

• MCP server that Claude Code instances connect to
• Shared file system access with security constraints
• Real-time chat participation with other agents
• Task execution and progress reporting
• File change notifications and collaboration sync

Quick Start

1. Automated Setup

npm run setup

This will:

• Install all dependencies (including sqlite3)
• Create the shared workspace directory
• Test the MCP server
• Show Claude Desktop configuration instructions

🆕 New in v2.0: Enhanced CLI with role management, task templates, and tab completion!

2. Start the Central Hub

npm run server

This starts the hub server on http://localhost:3000 with a shared directory at ./shared

3. Configure Claude Desktop

🎯 Automatic Configuration (Recommended)

Generate the correct configuration for your environment:

npm run config

This creates:

• claude-config-windows.json - For Claude Desktop (Windows)
• claude-config-wsl.json - For Claude Code (WSL)

Note: The examples below show placeholder paths. When you run npm run config, it will generate the actual paths for your project location.

📋 Manual Configuration

Add the appropriate configuration to your Claude Desktop configuration file (usually at %APPDATA%\Claude\claude_desktop_config.json):

For Claude Desktop (Windows):

{
  "mcpServers": {
    "claude-symphony-of-one": {
      "command": "node",
      "args": ["C:\\path\\to\\your\\project\\mcp-server-wrapper.js"],
      "env": {
        "CHAT_SERVER_URL": "http://localhost:3000",
        "SHARED_DIR": "C:\\path\\to\\your\\project\\shared",
        "AGENT_NAME": "Claude-Agent-Windows"
      }
    }
  }
}

For Claude Code (WSL):

{
  "mcpServers": {
    "claude-symphony-of-one": {
      "command": "node",
      "args": ["/mnt/c/path/to/your/project/mcp-server-wrapper.js"],
      "env": {
        "CHAT_SERVER_URL": "http://localhost:3000",
        "SHARED_DIR": "/mnt/c/path/to/your/project/shared",
        "AGENT_NAME": "Claude-Agent-WSL"
      }
    }
  }
}

🔧 Note: The configurations use the smart wrapper script (mcp-server-wrapper.js) which automatically handles Windows/WSL path differences.

📖 For detailed Windows/WSL setup instructions, see WINDOWS_WSL_SETUP_GUIDE.md

4. Start User Orchestrator CLI (Optional)

npm run cli

This opens the orchestrator interface for managing agents and tasks.

5. Restart Claude Desktop

Restart Claude Desktop to load the MCP server. You should now see the Symphony of One tools available in Claude.

Configuration

Environment Variables

• CHAT_SERVER_URL: Hub server URL (default: http://localhost:3000)
• SHARED_DIR: Shared workspace directory (default: ./shared)

Manual Configuration (Alternative)

If you prefer manual setup, see the claude-config-example.json file for the exact configuration format.
