You're shortening links in a Claude chat, and now you don't need to context-switch to a browser tab. This MCP server connects to toui.io's API and exposes a single tool: shorten_url. It handles OAuth so your API key stays out of the chat transcript. You get back a toui.io short link (or your own custom domain if you're on Pro), complete with click analytics and an auto-generated QR code. Useful when you're drafting content, building campaigns, or generating documentation and want clean URLs without breaking your flow. The server runs remotely over streamable-http, so there's nothing to install locally.
