Show HN: Mkdnsite – Markdown-native web server for humans (HTML) and agents (md) (github.com) AI

Mkdnsite is an open-source “Markdown-native” web server that serves a directory or GitHub repo of .md files without a static-site build step. It renders HTML for browsers and uses HTTP content negotiation to return raw Markdown for AI agents (e.g., via Accept: text/markdown), along with an auto-generated /llms.txt and an optional MCP endpoint. The project supports Bun/Node/Deno, runtime editing without redeploy, and includes features like search, theming, math (KaTeX), Mermaid, and syntax highlighting.
