🔗 Claude Code Integration

Connecting to Claude Code

To use this MCP server with Claude Code, you need to configure Claude Code to recognize and connect to your server.

1. Automated Setup (Recommended)

Use the automated setup script for easy configuration:

# Navigate to your project directory
cd /Users/atsukisakai/Desktop/ai_collaboration_mcp_server

# Run automated setup with your DeepSeek API key
./scripts/setup-claude-code.sh --api-key "your-deepseek-api-key"

# Or with multiple providers
./scripts/setup-claude-code.sh \
  --api-key "your-deepseek-key" \
  --openai-key "your-openai-key" \
  --anthropic-key "your-anthropic-key"

# Alternative using pnpm
pnpm run setup:claude-code -- --api-key "your-deepseek-key"

The setup script will:

• ✅ Build the MCP server
• ✅ Create Claude Code configuration file
• ✅ Test the server connection
• ✅ Provide next steps

1b. Manual Setup

If you prefer manual setup:

# Navigate to your project directory
cd /Users/atsukisakai/Desktop/ai_collaboration_mcp_server

# Install dependencies and build
pnpm install
pnpm run build

# Set your DeepSeek API key
export DEEPSEEK_API_KEY="your-deepseek-api-key"

# Test the server
pnpm run verify-deepseek

2. Configure Claude Code

Create or update the Claude Code configuration file:

Note: There are two server options:

• simple-server.js - Simple implementation with DeepSeek only (recommended for testing)
• index.js - Full implementation with all providers and features

macOS/Linux:

# Create config directory if it doesn't exist
mkdir -p ~/.config/claude-code

# Create configuration file (simple server - recommended for testing)
cat > ~/.config/claude-code/claude_desktop_config.json << 'EOF'
{
  "mcpServers": {
    "ai-collaboration": {
      "command": "node",
      "args": ["/Users/atsukisakai/Desktop/ai_collaboration_mcp_server/dist/simple-server.js"],
      "env": {
        "DEEPSEEK_API_KEY": "your-deepseek-api-key"
      }
    }
  }
}
EOF

# Or use the full server for all features
# Replace simple-server.js with index.js in the args above

Windows:

# Create config directory
mkdir "%APPDATA%\Claude"

# Create configuration file (use your preferred text editor)
# File: %APPDATA%\Claude\claude_desktop_config.json

Design Principles

• Dependency Injection: Clean architecture with InversifyJS
• Strategy Pattern: Pluggable collaboration strategies
• Provider Abstraction: Unified interface for different AI services
• Performance: Efficient caching and rate limiting
• Observability: Comprehensive metrics and logging
• Extensibility: Easy to add new providers and strategies

🔧 Configuration

• Providers: AI provider configurations and credentials
• Strategies: Strategy-specific settings and timeouts
• Cache: Caching behavior (memory, Redis, file)
• Metrics: Performance monitoring settings
• Logging: Log levels and output configuration

Environment Variables

Variable	Description	Default
DEEPSEEK_API_KEY	DeepSeek API key	Required
OPENAI_API_KEY	OpenAI API key	Optional
ANTHROPIC_API_KEY	Anthropic API key	Optional
O3_API_KEY	O3 API key (defaults to OPENAI_API_KEY)	Optional
MCP_PROTOCOL	Transport protocol	stdio

• Tool Metrics: Usage statistics per MCP tool
• Cache Metrics: Hit rates, memory usage
• System Metrics: CPU, memory, and resource utilization

OpenTelemetry Integration

The server supports OpenTelemetry for distributed tracing and metrics collection:

metrics:
  enabled: true
  export:
    enabled: true
    format: "opentelemetry"
    endpoint: "http://localhost:4317"

🧪 Testing

Test Coverage

• Unit Tests: 95+ individual component tests
• Integration Tests: End-to-end MCP protocol testing
• E2E Tests: Complete workflow validation
• API Tests: Direct provider API validation

Running Tests

# Run all tests
pnpm test

# Run with coverage
pnpm run test:coverage

# Run specific test suites
pnpm run test:unit
pnpm run test:integration
pnpm run test:e2e

# Verify API connectivity
pnpm run verify-deepseek

🚢 Deployment

Docker

# Build image
docker build -t claude-code-ai-collab-mcp .

# Run container
docker run -d \
  -e DEEPSEEK_API_KEY=your-key \

  claude-code-ai-collab-mcp

Production Considerations

• Load Balancing: Multiple server instances for high availability
• Caching: Redis for distributed caching
• Monitoring: Prometheus/Grafana for metrics visualization
• Security: API key rotation and rate limiting
• Backup: Regular configuration and data backups
