• Automatic Fallback: Console logging when MCP transport isn't ready

# 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

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

• 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

• 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

• 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

• 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

# 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)

Examples of using the IT Tools MCP server with VS Code Copilot Chat for secure password hashing and creative ASCII art generation.

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

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.

1. Create a tool directory in appropriate category under src/tools/
2. Define tool with input schema using Zod in its index.ts
3. Export registration function for dynamic loading
4. Rebuild with npm run build
