MarkView MCP server

MarkView is a small macOS app that shows Markdown files in a proper window, with formatting, tables, diagrams and code colours. This MCP server is the bridge that lets your AI send Markdown straight into that window. It is handy if you use Claude Code or Claude Desktop on a Mac and you want to actually see the notes, docs or reports your AI writes instead of reading raw text in the chat.

What this MCP server does

You ask your AI to write or open some Markdown. The AI passes that text or file name to this helper. The helper hands it to the MarkView app on your Mac. MarkView opens a window and renders it, with headings, tables, code colours and diagrams looking the way they should. If the AI keeps editing the text, the window updates as it goes, so you can watch the document take shape.

What you can do with it

• Preview Markdown your AI just wrote in a live window
• Open an existing .md file from your Mac in MarkView
• Watch a document update while your AI keeps editing it
• See tables, task lists and footnotes rendered properly
• View Mermaid diagrams like flowcharts and pie charts
• Read code blocks with syntax colours instead of plain text

Try asking your AI

• “Write me a project plan in Markdown and show it in MarkView”
• “Open my notes.md file in MarkView”
• “Draft a README for this folder and preview it as you go”
• “Turn this list into a Markdown table and show me the result”

What it gives back to you

You get a native MarkView window on your Mac showing the rendered Markdown. In the chat itself, your AI usually just confirms that it opened or updated the preview. If you asked it to open a file, the window shows that file's content. As the AI edits the text, the window refreshes so you always see the latest version.
