ouicu for JavaScript: SDK and MCP server

ouicu gives the site running on your computer a public https link, like https://studiolund.ouicu.app, so a client or teammate can open it on any phone or computer. This repository holds ouicu's two npm packages:

Package	What it does
@ouicu/mcp	An MCP server: Claude Code, Cursor, Codex and other coding agents share your dev server or upload a build and hand you the link.
@ouicu/sdk	ouicu from Node: share a port, upload a built site, list shares and sites, see who opened them.

MCP server

npx -y @ouicu/mcp setup claude-code

The same works for cursor, codex, vscode, windsurf and claude-desktop. Then ask your agent for a link in your own words, for example "build the gallery page and send me a ouicu link". The agent shares the dev server, or uploads the build, and hands back the address.

It is listed in the official MCP Registry as com.ouicu/mcp. Docs: ouicu.com/docs/mcp. More in packages/mcp.

SDK

npm install @ouicu/sdk

import { Ouicu } from "@ouicu/sdk";

const ouicu = new Ouicu({ apiKey: process.env.OUICU_API_KEY });
const share = await ouicu.share({ port: 3000, name: "studiolund" });
console.log(share.url); // https://studiolund.ouicu.app

Node 20 or later, no other dependencies. Docs: ouicu.com/docs/sdk. More in packages/sdk.

What ouicu is for

Showing work in progress to people who aren't developers: a reserved name keeps the same link for each client, a password or a list of invited people keeps it private, you get an email when someone opens it, and the last version stays up while your laptop sleeps. It passes web pages (HTTP and WebSockets), not TCP, video or downloads. Plans and limits: ouicu.com/docs/plans.

The ouicu command line tool itself is installed from ouicu.com; its releases are at kroqdotdev/ouicu-cli.
