Phrase Flip for Claude

A privacy-first, 100% local translation MCP server for Claude and other AI chat clients. Ask your assistant to “phrase-flip this into Spanish” and it renders an interactive card with a subset of sentences translated — hover to reveal the original. Everything is translated on your own machine; phraseflip.com receives nothing.

Add to Claude

Open Claude Desktop and add the server in one click, or paste the config below.

One-click install isn’t available in every client yet — the copy-paste config below works everywhere that supports MCP.

Copy-paste install

Add this to your Claude Desktop config file, then restart Claude Desktop.

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

1. Paste the snippet into your claude_desktop_config.json.
2. Fully quit and reopen Claude Desktop.
