Before you start

To use the Leonardo.Ai Connector, you’ll need:

• An AI assistant that can use MCP servers, such as:
  • Cursor
  • VS Code (with a compatible plugin or extension, such as GitHub Copilot)
• A Leonardo.Ai account
• Any Leonardo.Ai API plan

Connect your AI assistant

Create an API Key

The Leonardo.Ai Connector currently requires an API key to be created. Follow the instructions here to create your API Key before continuing.

Configure your AI assistant

Each AI assistant requires specific configuration to communicate with the Leonardo.Ai Connector. Follow the instructions below for your assistant.

Cursor

ℹ️

MCP tools are currently only available in Agent mode.

You can manually create the configuration with the following steps:

1. If you haven’t already configured an MCP server in your project directory, create the configuration directory and file:

   mkdir -p .cursor
   touch .cursor/mcp.json

2. Add the following configuration for the Leonardo.Ai MCP server to .cursor/mcp.json:

   {
     "mcpServers": {
       "leonardo-ai": {
         "url": "https://mcp.leonardo.ai/v1/mcp",
         "headers": {
           "API-Key": "replace this string with your api key"
         }
       }
     }
   }

For more information, see the Cursor MCP documentation.

Check the connection

To confirm the Leonardo.Ai Connector is working:

Look for visual indicators in your AI assistant app. For example, in Cursor you can go to Cursor Settings → MCP and see the Leonardo.Ai MCP server listed.
