One Design for Claude (MCP)
Every one.design tool that can run outside a browser, for Claude and any app that speaks MCP. Everything runs on your own computer: your files are read and saved locally and never uploaded.
Setup guide, examples and questions: **https://one.design/mcp**
The few tools that run an AI model in the browser (Cutout, Blur Faces, Magic Eraser, Brand Guidelines) open on one.design instead, where they also run on your device.

Install
Needs Node.js 20 or newer.
One command (adds it to Claude Desktop, Claude Code, Codex and Cursor, wherever they're installed, and
keeps a .bak of any config it changes):
npx -y one-design-mcp setup--dry-run shows what it would change, --app desktop|code|codex|cursor picks one app, and --remove
takes it out again. An agent with a terminal (Claude Code, Codex, Cursor) can run it for you: ask it to
"set up the One Design MCP server with npx -y one-design-mcp setup".
Claude Code
claude mcp add one-design -- npx -y one-design-mcpCodex
codex mcp add one-design -- npx -y one-design-mcpClaude Desktop: Settings → Developer → Edit Config, then add to claude_desktop_config.json:
{
"mcpServers": {
"one-design": { "command": "npx", "args": ["-y", "one-design-mcp"] }
}
