Markdown Editor MCP App

What it does

This MCP app renders a full-featured, interactive Markdown editor directly inside compatible hosts. It combines the power of the Monaco Editor (the engine behind VS Code) with a real-time GitHub Flavored Markdown preview, providing a professional writing environment without leaving the AI interface.

Key features

• Monaco-powered Editing: Full syntax highlighting, line numbers, and code folding.
• Live GFM Preview: Instant rendering of tables, task lists, and styled code blocks.
• Advanced Export: Generate standalone HTML files or high-quality PDFs via Puppeteer.
• Secure File I/O: Open, save, and create markdown files with automatic backups and path sanitization.
• HTML Import: Convert existing HTML files back into markdown using Turndown.
