VibeAround Live Preview

Start a live preview so the user can see your work via a shareable URL.

Steps

1. Start the server (if not already running)

2. Get your session ID

Use the /va-session skill to resolve your current session ID.

3. Call preview

Tool: preview
Server: vibearound
Arguments:
  port: <port>
  cwd: "<current working directory>"
  session_id: "<session_id from step 2>"  (pass if available)
  title: "<description>"  (optional)

4. Present BOTH links to the user

Always show both Owner and Share URLs. Never omit either link.

Format:

Preview ready:
- Owner: <owner_url>
- Share: <share_url> (expires in 10 min)

VibeAround Live Preview

After you finish building a web application, HTML page, or any browsable artifact, start a live preview so the user can see the result immediately via a shareable URL.

When to Use

You just started a dev server (next dev, vite, python -m http.server, etc.)
You created HTML/CSS/JS files the user should see
The user asked to "show me", "preview", or "let me see it"
Only when the VibeAround MCP server is connected

Proactive behavior: After starting a dev server or creating a web artifact, proactively ask the user if they'd like a preview link (e.g. "Want me to generate a preview link so you can see it on your phone?"). If the user confirms, call preview. Do NOT call the tool without asking first.

Prerequisites

The VibeAround MCP server must be connected (server name: vibearound). If not available, tell the user to start the VibeAround desktop app.

Steps

1. Start the server (if not already running)

Before calling preview, make sure:

The port you want is free: lsof -i :<port> should return nothing
The server is actually listening (wait for "Listening on..." or similar in the output)
Use --host 0.0.0.0 when available for broader compatibility

2. Call preview

Tool: preview
Server: vibearound
Arguments:
  port: <the port your server is running on>
  cwd: "<current working directory>"
  title: "<short description of what you built>"  (optional)

If the tool says the workspace is not registered, call register_workspace with the cwd first, then retry.

3. Share the URL

Include the returned URL in your reply. The user can tap it to see the live preview in their browser or phone. The link expires in 5 minutes.

Error Handling

MCP server not available: The VibeAround desktop app may not be running.
Workspace not registered: Call register_workspace first, then retry.
Port in use: Check with lsof -i :<port> and choose a different port.
