IT Tools MCP Server
WARNING
This project is deprecated and no longer maintained.
It was built as a learning exercise to explore AI-assisted development and the Model Context Protocol (MCP). No further updates, bug fixes, or pull requests will be accepted. The repository is kept for reference only.
If you need an actively maintained MCP server with IT utilities, look for community alternatives.
๐ Note: A condensed version of this README is automatically synced to Docker Hub due to character limits.
A comprehensive Model Context Protocol (MCP) server that provides access to over 121 IT tools and utilities commonly used by developers, system administrators, and IT professionals. This server exposes a complete set of tools for encoding/decoding, text manipulation, hashing, network utilities, and many other common development and IT tasks.

๏ฟฝ 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 runtimelogging_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
๐ง MCP Protocol Utilities
This server implements the complete MCP 2025-06-18 specification including advanced utilities:
Ping Utility
- Health Checking: Use
pingrequests 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.progressTokenin requests to enable progress notifications - Notifications: Server sends
notifications/progresswith current status
Request Cancellation
- Graceful Cancellation: Send
notifications/cancelledto 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

๐๏ธ Architecture & Development
Built with TypeScript, Zod validation, and MCP SDK for robust, type-safe operation.
๐ค 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:
- ๐ง Tool Implementation: All tools designed and implemented with AI assistance
- ๐ฆ Docker Setup: Complete containerization with GitHub Actions CI/CD pipeline
- ๐ Schema Cleanup: Systematic removal of unsupported Zod keywords from all tool definitions
- ๐ Documentation: Comprehensive README with usage examples and tool catalogs
- ๐ 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
- Create a tool directory in appropriate category under
src/tools/ - Define tool with input schema using Zod in its
index.ts - Export registration function for dynamic loading
- Rebuild with
npm run build
