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 (
appbadge) and the npm MCP wrapper (npmbadge) 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.

| Preview only | Editor + Preview |
|---|---|
![]() | ![]() |
One command to wire MarkView into every Claude Code session:
claude mcp add --transport stdio --scope user markview -- npx mcp-server-markview
That's it. Claude can now call preview_markdown to render any markdown string in a native macOS window, or open_file to open any .md file directly.
| Tool | What it does |
|---|---|
preview_markdown | Render markdown content in a live-reloading MarkView window |
open_file | Open an existing .md file in MarkView |
Add to ~/Library/Application Support/Claude/claude_desktop_config.json:
{
"mcpServers": {
"markview": {
"command": "npx",
"args": ["mcp-server-markview"]
}
}
}
Note: MCP servers belong in
~/.claude.json(Claude Code) orclaude_desktop_config.json(Claude Desktop), not~/.claude/settings.json.
