Home Server Development Environment

A local AI-powered automation platform built on Ubuntu Linux, integrating Claude Code with n8n workflows, local LLM inference, and browser automation.

What's Running

Service	Port	Purpose
n8n	8567	Visual workflow automation
Ollama	11434	Local LLM inference
system-stats	9998	CPU/memory/disk metrics
container-health	9997	Docker container monitoring
cpu-server	9999	Host CPU monitoring

Active Workflows (n8n)

• CPU Monitor - Discord alert when CPU ≥ 80%
• Memory Monitor - Checks every 5 minutes
• Disk Monitor - Checks every 5 minutes
• Container Health - Checks every 2 minutes

MCP Integrations

Claude Code can interact with all services via MCP:

# Examples of what Claude can do:
- List/create/execute n8n workflows
- Generate text with local Ollama models
- Query SQLite databases
- Automate browser tasks
- Search the web with Exa

Projects

Directory	Description
/root/n8n-mcp/	Docker stack for n8n + monitoring services
