I built a simple CLI tool called `mdts` (Markdown Tree Server) that serves Markdown files from a local directory with a web-based interface.

Key features: - File tree navigation in the browser - Instant preview of Markdown content - Zero configuration: run a single command and it opens in your browser

It's useful for browsing local notes, documentation, or any Markdown-based wiki structure.
