MarkView

paulhkang94/markview

Gives Claude two tools to render markdown in a native macOS window while you work. Call preview_markdown with any markdown string and it opens a live Swift/SwiftUI preview with GitHub Flavored Markdown, Mermaid diagrams, and syntax highlighting. Call open_file to launch an existing .md file directly. The renderer is a full featured macOS app with Quick Look integration, split pane editing, and markdown linting built on swift-cmark. No Electron overhead. Useful when Claude is drafting documentation, READMEs, or technical specs and you want to see the formatted output immediately without switching contexts or saving to disk first.

Readme

MarkView

App npm Glama

Native macOS markdown preview with MCP server for Claude Code. Claude writes markdown — MarkView renders it live, in a real native window, while you work.

Versions: The macOS app (app badge) and the npm MCP wrapper (npm badge) are versioned independently. App releases happen when the Swift binary changes; npm patches happen for MCP server improvements. Both badges always show the latest of each.
