Overview

AI-generated overview

A remote MCP server that creates temporary four-digit short links so an assistant can help someone open a public website on a TV, console or other device.

What you can do
Create a four-digit short link for a public URL, returning the code, a versioned preview link, expiry and typing instructions for TV browsers, with a request_id to safely retry a lost response.
When to use it
Useful when a user needs to type a website address on a TV remote, console browser or another device where long URLs are awkward, and a temporary handoff link is enough.
Requirements
A remote endpoint at lkj.cx over streamable HTTP; no account, API key, environment variable or header is declared. The service is a free beta and may apply capacity limits with a retry_after_seconds value.
Before you install
Links are public and temporary: codes are guessable and not credentials, expire after one hour idle, and can be recycled after expiry and at least 30 days. Do not use for private links, permanent bookmarks, casting video or transferring sign-ins, and do not follow the open route to extend expiry.

Installation

In SourceWeft

  1. Open LKJ — four-digit short links for TV browsers in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/cx.lkj%2Fshort-links/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
