Troubleshooting

Common Issues

API Key Authentication Failed

Symptoms: Access denied errors, Invalid API key messages, 401 Unauthorized

Cause: Invalid or expired API key

Solution:

• Verify API key is correct and active in AgentBay Console
• Check API key permissions and quotas
• Regenerate API key if expired or compromised
• Ensure API key is properly URL-encoded in SSE endpoint

Concurrent Instance Limit Exceeded

Symptoms: Resource allocation errors, Instance creation failures

Cause: Public beta limit of 10 concurrent instances reached

Solution:

• Wait for existing instances to complete or terminate them
• Optimize workflows to use fewer concurrent instances
• Consider upgrading to production plan for higher limits
• Monitor instance usage and implement resource pooling

Environment Session Lost

Symptoms: Session disconnection, State not persisted, Data loss

Cause: Network connectivity issues or session timeout

Solution:

• Use EXTERNALID parameter for persistent sessions
• Implement session restoration mechanisms
• Save work frequently to persistent storage
• Check network stability and connection quality

Screen Streaming Performance Issues

Symptoms: Lag in browser streaming, Poor video quality, Connection drops

Cause: Network bandwidth limitations or high latency

Solution:

• Check internet connection speed and stability
• Use lower quality settings for better performance
• Choose nearest edge location for better latency
• Optimize browser usage for streaming performance

Installation Problems

Symptoms: Cursor fails to install, Application won't start

Cause: System requirements not met or corrupted download

Solution:

• Check minimum system requirements
• Re-download installer from official website
• Run installer as administrator (Windows)
• Check available disk space and permissions

MCP Settings Not Found

Symptoms: No MCP option in settings, Missing configuration section

Cause: Feature not available in current Cursor version

Solution:

• Update Cursor to latest version
• Check if MCP support is enabled in your subscription
• Look for "Extensions" or "Integrations" section instead
• Contact Cursor support for feature availability

Server Configuration Fails

Symptoms: Settings not saving, Configuration errors

Cause: Invalid server path or configuration parameters

Solution:

• Verify server executable path is correct
• Check server installation and permissions
• Use absolute paths instead of relative paths
• Test server command from system terminal first

AI Assistant Not Using MCP Tools

Symptoms: Tools available but AI not using them, Limited functionality

Cause: AI assistant not properly configured for MCP integration

Solution:

• Restart Cursor after configuration changes
• Check AI assistant settings for tool permissions
• Verify MCP server is running and responding
• Try explicitly asking AI to use specific tools

AgentBay not appearing in Cursor

Symptoms: Server not listed, Tools not available

Cause: Configuration or installation issue

Solution:

• Verify configuration syntax
• Check AgentBay installation
• Restart Cursor
• Check logs for error messages
