@lepion/mcp-server-specnavigator

An intelligent MCP (Model Context Protocol) server for navigating, exploring, and understanding the Model Context Protocol specification with dynamic markdown tree generation, intelligent section navigation, and upstream synchronization.

🎯 Purpose

The MCP SpecNavigator server transforms the way you interact with MCP specifications by providing:

• 🌳 Dynamic Markdown Trees - Navigate specifications with auto-generated tree structures
• 🔍 Intelligent Search - Find sections instantly with keyword search and anchor links
• 🔄 Upstream Sync - Stay updated with the latest specification changes
• 📚 Contextual Documentation - Access specific sections on-demand
• ⚡ Performance Optimized - Efficient caching for fast responses

📋 Attribution

This project is based on and provides navigation for the Model Context Protocol specification created by the Model Context Protocol team. This is a wrapper/navigation tool that enhances access to the original specification.

✨ Features

• Dynamic Markdown Tree Generation: Automatically generates navigable tree structures from MCP specifications
• Intelligent Section Search: Find sections by keywords and get direct anchor links
• Specification Caching: Efficiently caches specifications to reduce network requests
• Upstream Synchronization: Check for updates from the official MCP repository
• Section Content Retrieval: Get specific sections of the specification on demand
