� MCP Logging Capabilities

This server includes full MCP logging support with the following features:

Log Levels

• debug (0): Detailed debug information
• info (1): General information messages
• notice (2): Normal but significant events
• warning (3): Warning conditions
• error (4): Error conditions
• critical (5): Critical conditions
• alert (6): Action must be taken immediately
• emergency (7): System is unusable

Logging Tools

• logging_setLevel: Change the minimum logging level at runtime
• logging_status: View current logging configuration and available levels

Environment-Aware Behavior

• Development Mode: Debug level by default, enhanced console output
• Production Mode: Info level by default, clean output for MCP compliance
• Automatic Fallback: Console logging when MCP transport isn't ready

Usage Examples

# Check current logging status
echo '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"logging_status","arguments":{}}}' | npx it-tools-mcp

# Change log level to debug
echo '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"logging_setLevel","arguments":{"level":"debug"}}}' | npx it-tools-mcp

# Change log level to error (only show errors and above)
echo '{"jsonrpc":"2.0","id":3,"method":"tools/call","params":{"name":"logging_setLevel","arguments":{"level":"error"}}}' | npx it-tools-mcp

🔧 MCP Protocol Utilities

This server implements the complete MCP 2025-06-18 specification including advanced utilities:

Ping Utility

• Health Checking: Use ping requests to verify connection status
• Automatic Response: Server responds promptly with empty result per MCP spec
• Connection Monitoring: Implement periodic health checks

Progress Tracking

• Long-Running Operations: Receive progress updates for time-consuming tasks
• Progress Tokens: Include _meta.progressToken in requests to enable progress notifications
• Notifications: Server sends notifications/progress with current status

Request Cancellation

• Graceful Cancellation: Send notifications/cancelled to abort in-progress requests
• Resource Cleanup: Server properly frees resources when requests are cancelled
• Race Condition Handling: Robust handling of timing edge cases

Sampling Support

• LLM Integration: Server can request LLM completions from clients using sampling/createMessage
• Model Preferences: Support for model selection hints and capability priorities (cost, speed, intelligence)
• Content Types: Support for text, image, and audio content in sampling requests
• Agentic Workflows: Enable AI-powered tool operations through nested LLM calls
• Client Control: Clients maintain full control over model access and user approval

Protocol Examples

# Test connection health with ping
echo '{"jsonrpc":"2.0","id":1,"method":"ping"}' | npx it-tools-mcp

# Request with progress tracking
echo '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"some_tool","arguments":{},"_meta":{"progressToken":"track123"}}}' | npx it-tools-mcp

# Cancel a request (send as notification)
echo '{"jsonrpc":"2.0","method":"notifications/cancelled","params":{"requestId":"2","reason":"User cancelled"}}' | npx it-tools-mcp

# Test sampling capabilities
echo '{"jsonrpc":"2.0","id":4,"method":"tools/call","params":{"name":"mcp_sampling_demo","arguments":{"message":"What is the capital of France?","modelPreference":"claude","systemPrompt":"You are a helpful assistant.","maxTokens":100}}}' | npx it-tools-mcp

🏗️ Architecture & Development

Built with TypeScript, Zod validation, and MCP SDK for robust, type-safe operation.

🤖 AI-Assisted Development

This project was developed using VS Code, Copilot Chat Agent, Playwright MCP, and the Claude Sonnet 4 Model, demonstrating the power of AI-assisted software development:

• Intelligent Code Generation: Claude Sonnet analyzed requirements and generated comprehensive tool implementations
• Schema Validation: Automatically identified and resolved JSON schema validation issues across tools
• Docker Optimization: Created production-ready Docker workflows and multi-stage builds
• Documentation: Generated comprehensive README with examples and tool reference tables
• Testing: Implemented robust error handling and validation throughout the codebase

Key AI Contributions:

• 🔧 Tool Implementation: All tools designed and implemented with AI assistance
• 📦 Docker Setup: Complete containerization with GitHub Actions CI/CD pipeline
• 🔍 Schema Cleanup: Systematic removal of unsupported Zod keywords from all tool definitions
• 📚 Documentation: Comprehensive README with usage examples and tool catalogs
• 🚀 Production Ready: Docker Hub publishing, badges, and professional deployment setup

This showcases how AI can accelerate development while maintaining code quality, proper architecture, and comprehensive testing.

Adding New Tools

1. Create a tool directory in appropriate category under src/tools/
2. Define tool with input schema using Zod in its index.ts
