Install wan555 - fast preview - WAMU-Merge-VisualEffects WAN2.2 I2V LIGHTNING in Cursor

What you need first

• Cursor, installed.
• Nothing else: the server runs on its publisher's machines and Cursor connects to it.

Steps

1. Open ~/.cursor/mcp.json, or create it. For one project only, use .cursor/mcp.json in that project.
2. Add this block. If the file already has mcpServers, add only the entry inside it.

{
  "mcpServers": {
    "wan555": {
      "url": "https://persie2020-wan555.hf.space/gradio_api/mcp/sse"
    }
  }
}

3. Save the file. In Cursor's settings, find the server in the MCP section and turn it on if it is off.

Check it worked

Ask Cursor: List the tools of wan555. It should list 3 tools.

If it does not start

401 Unauthorized

The endpoint wants a sign-in or a key. Sign in when Cursor asks.

Nothing changes after a restart

The file is not valid JSON any more. Look for a missing comma where the block was added.
