Getting Your Vestaboard API Key

1. Visit Vestaboard Developer Portal
2. Sign in with your Vestaboard account
3. Go to "Read/Write API" section
4. Generate a new API key for your board
5. Copy the key to your .env file

Usage

Adding to Cursor as an MCP Server

1. Open Cursor Settings (Cmd/Ctrl + ,)
2. Go to "Features" → "Model Context Protocol"
3. Add a new MCP server by copying and pasting this JSON configuration:

{
  "mcpServers": {
    "vestaboard": {
      "command": "npx",
      "args": ["-y", "tsx", "path/to/vestaboard-mcp/index.ts"],
      "env": {
        "VESTABOARD_API_KEY": "YOUR_API_KEY"
      }
    }
}

Important:

• Replace /absolute/path/to/vestaboard-mcp with the actual absolute path to your cloned repository
• Replace your_vestaboard_api_key_here with your actual Vestaboard API key

1. Save the configuration and restart Cursor

Using with Cursor

Once configured, you can ask Cursor to display messages on your Vestaboard using natural language. Cursor will automatically use the display_message tool to send messages to your Vestaboard.

Examples:

• "Display 'Good Morning!' on my Vestaboard"
• "Show a colorful welcome message on the Vestaboard"
• "Put 'Meeting in 5 mins' on my Vestaboard in red"
• "Draw a minimal portrait of a Pikachu on my Vestaboard"
