Personal Applied AI System · Daily personal use

LifeOS

A personal exploration of Claude and MCP as the operating system for life administration.

LifeOS is a personal Claude-and-MCP orchestration system that treats life administration as software. Ingests communications streams (email across multiple accounts, postal scans, downloads), extracts structured signal, cross-links against authoritative personal records, and proactively manages recurring real-world actions. Runs daily, powered by a self-authored job-application-tracking MCP, twelve-plus scheduled tasks, and broad orchestration of open-source MCPs across Obsidian, SQL, document OCR and CLI integrations.

Core technologies

  • Claude API
  • Anthropic MCP
  • Obsidian
  • SQL
  • Python (AI-paired)
  • Custom MCP servers

Key features

  • Ingestion pipeline across email, postal scans and downloads with per-domain routing into structured knowledge bases.
  • Twelve-plus scheduled tasks running daily ingestion, briefings, proactive monitoring and contextual actions.
  • Self-authored job-application-tracking MCP that orchestrates the full lifecycle of an application from JD analysis through draft management.
  • {"Self-improving skills"=>"internal performance tracking informs external skill and tool research so the system iterates on its own deployment patterns over time."}
