Overview

MarkView is a native macOS application that provides real-time markdown preview capabilities with MCP server integration. It features a SwiftUI-based split-pane editor with live reloading, GitHub Flavored Markdown support via swift-cmark, Mermaid diagram rendering, and syntax highlighting through Prism.js. The MCP server exposes two main tools: preview_markdown for rendering content in a native window and open_file for opening markdown files directly. The architecture is well-structured with separate modules for the core rendering engine, UI components, and MCP server functionality.
