From AntJanus, the personal encyclopedia · List
This is a list of open source, side projects, AI experiments, and creative work by Antonin Januska. It is sorted by kind; tables sort by any column.

Public repositories on GitHub.
A dashboard and Model Context Protocol server for a project portfolio whose entire state lives in markdown files. Twenty-five zod-typed MCP tools let Claude Code read roadmaps, advance sessions, and work QA queues without anyone opening the UI. No database: the files are the source of truth, and git is the audit log.
