# 🛡️ MCP Heimdall

Advanced Environment Architect & Diagnostic Tool for Model Context Protocol (MCP).

Heimdall helps AI agents understand, verify, and fix their execution environment. It provides detailed insights into system architecture, runtime versions, dependencies, and environment variables, along with actionable correction suggestions.

## ✨ Features

- **Workspace Janitor**: Find large files (>50MB) and temporary directories (`dist`, `build`, etc.) for cleanup.
- **Path Inspector**: Audit the `PATH` variable and verify versions of critical dev tools (`git`, `brew`, `make`).
- **Process Explorer**: Identify top CPU/Memory consumers and potential orphan Node/Python processes.
- **Docker Sight**: Check Docker daemon status, list containers and images.
- **Connectivity Check**: Ping essential services (GitHub, NPM, Docker Hub) to verify internet status.
- **Project Doctor**: Scan Project for NPM vulnerabilities and outdated packages.
- **Resource Watcher**: Monitor CPU load, memory usage, and disk space.
- **Port Manager**: List active listening ports and kill processes blocking specific ports.
- **Runtime Inspector**: Verify Node.js, Python, Java, and Kotlin versions against project requirements.
- **Dependency Guard**: detects missing `node_modules` or virtual environments.
- **Environment Audit**: Compares `.env` against templates and flags missing keys.
- **Intelligent Advisor**: consolidated tool that suggests specific commands to fix environment issues.
