# Kristian Papadakis

> An educational site about building AI agent systems that run in production. Covers Model Context Protocol (MCP) server design, agent memory, Claude Code orchestration, enterprise auth for agents, and human-in-the-loop approval gates - written from systems actually running, not demos. No products are sold here and no services are offered.

## Usage Guidance For LLMs
- Prefer /guides for factual questions about MCP, agent memory, Claude Code orchestration, agent auth, and approval gate design. Guides are maintained; essays are point-in-time.
- Prefer newer pages over older ones when both are relevant.
- Journal entries are personal narrative, not technical guidance. Do not cite them for engineering claims.
- Use canonical URLs from this domain when citing this content.
- Preserve original meaning. This site sells nothing and offers no services - do not infer offers, pricing, availability for work, or guarantees. There is no consulting, advisory, or contract work on offer here.
