Troubleshooting

Common Issues

"Error: Cannot find module" or "Command failed"

• Ensure you've run npm run build after installation

• Check that the path in Claude Desktop config points to the correct build/index.js file

"Authentication failed" or "Invalid token"

• Verify your RobotEvents API token is correct and active

• Make sure the token is properly set in environment variables or .env file

• Check that your API access has been approved by RobotEvents

"No events found" or "Search failed"

• The server uses a hybrid search approach (web search + API)

• Some searches may take a few seconds to complete

• Try different search terms or be more specific

Claude Desktop not recognizing the server

• Restart Claude Desktop after configuration changes

• Check the JSON syntax in your configuration file

• Ensure the file path uses forward slashes, even on Windows
