ouicu

@ouicu/mcp

An MCP server for ouicu. A coding agent can share the dev server it is working on, or put a built site up, and hand back a link to send to someone: "build the landing page and send me a link" in one turn.

Set up

npx -y @ouicu/mcp setup claude-code

or claude-desktop, cursor, vscode, codex, windsurf. If this computer is not logged in to ouicu, it logs you in first: it shows a code, opens ouicu.com in your browser to approve it, and saves the key where the ouicu CLI keeps it. Then it adds the server to the tool, for every project. The key never goes into the tool's settings; the server reads it from the credentials file, so ouicu login and the server share one login.

When the tool's own command (claude, codex) is missing, it prints the command to run by hand. For Claude Code that is:

claude mcp add -s user --transport stdio ouicu -- npx -y @ouicu/mcp

Any other MCP client starts it as npx -y @ouicu/mcp (stdio):

{  "mcpServers": {    "ouicu": { "command": "npx", "args": ["-y", "@ouicu/mcp"] }  }}

Sharing a port also needs the ouicu CLI, 0.1.7 or later (0.1.8 to share with only invited people):

curl -fsSL https://ouicu.com/install.sh | sh

On Windows, in PowerShell:

irm https://ouicu.com/install.ps1 | iex

Tools

Each answers in words an agent can pass on, with the same as structured content. Links are public: anyone who has one can open it unless it has a password or is only for invited people. On the Free plan, people opening a link in a browser first see a short notice from ouicu saying who shared it.

Shares the server starts run inside it, through the CLI, and stop when it stops or with ouicu_stop_share. For a link that outlives the session, use ouicu_deploy.

Only invited people

On Pro, ouicu_share_port takes allow: email addresses, or @ and a domain (@client.com) for everyone at one. Only those people can open the link. ouicu does not send it to them; you do, as with any link. On opening it, each types their email address on ouicu's page and, if it is on the list, gets a sign-in link by email. Your own address always gets in. allow does not go with password. The tool says when only invited people can open a share, and ouicu_list_shares and ouicu_list_sites say "only invited people can open it" for those.

Asking again for a port the server already shares hands back that share only when the same people can open it (anyone, the same password or the same list); otherwise the tool says to stop it first.

Without a key

The server starts with one tool, ouicu_login. It opens the approval page in the person's browser when it can (otherwise it answers with the code and the address for the agent to pass on) and waits for the approval. The other tools then appear without a restart. When the saved key stops working, ouicu_login comes back.

Settings

The server reads OUICU_API_KEY (a key from ouicu.com, instead of the saved login), OUICU_API (another ouicu than ouicu.com), OUICU_TUNNEL and OUICU_BIN (the CLI to run). From code:

import { createServer } from "@ouicu/mcp";import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
await createServer().connect(new StdioServerTransport());
