Testing

1. Test the server directly:

   npm start

2. Test with a simple MCP client:

   echo '{"jsonrpc": "2.0", "method": "tools/list", "id": 1}' | npm start

Development Mode

Run the server in development mode with debugging:

npm run dev

This enables additional logging and the Node.js inspector for debugging.

🚨 Troubleshooting

Common Issues

1. "API key is required" Error

Problem: The extension can't find your API key.

Solution:

• Ensure you've set the MMAUDIO_API_KEY environment variable
• Or create a config.js file with your API key
• Verify the API key is correct and active

2. "Connection refused" or Network Errors

Problem: Can't connect to MMAudio API.

Solution:

• Check your internet connection
• Verify the base URL is correct
• Check if there are any firewall restrictions

3. "Insufficient credits" Error

Problem: Your MMAudio account doesn't have enough credits.

Solution:

• Check your account balance at mmaudio.net/dashboard
• Purchase additional credits if needed
• Use the validate_api_key tool to check your account status

4. MCP Client Not Detecting Extension

Problem: Your MCP client (Cursor, Claude Desktop) doesn't show MMAudio tools.

Solution:

• Verify the configuration path in your MCP client settings
• Ensure Node.js is in your PATH
• Check the server logs for errors
• Restart your MCP client

Debug Mode

Enable debug mode for detailed logging:

DEBUG=true MMAUDIO_API_KEY=your-key node server/index.js

Logs

The server logs to stderr. You can redirect logs to a file:

node server/index.js 2> mmaudio.log
