Summary
This is a diagnostic toolkit that gives Claude visibility into your development environment. It exposes tools to check runtime versions (Node, Python, Java, Kotlin), scan for npm vulnerabilities, monitor system resources, audit PATH and environment variables, inspect Docker containers, and kill processes blocking ports. The standout feature is suggest_corrections, which runs all checks at once and returns prioritized fixes for whatever's broken. Reach for this when Claude needs to troubleshoot why a project won't build, verify dependencies are installed, or clean up workspace bloat. It's essentially giving the AI eyes into your shell environment so it can diagnose problems instead of guessing.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.

🛡️ 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
PATHvariable 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- Project Doctor: Scan Project for NPM vulnerabilities and outdated packages.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_modulesor virtual environments. - Environment Audit: Compares
.envagainst templates and flags missing keys. - Intelligent Advisor: consolidated tool that suggests specific commands to fix environment issues.
