Troubleshooting

Common Issues

MCP Server Not Connecting

Symptoms: Server not appearing in tools list, Connection timeout, MCP tools unavailable

Cause: Incorrect configuration or server not starting

Solution:

• Verify mcp_settings.json syntax is correct
• Check that Node.js and npx are installed and in PATH
• View Roo Code output panel for error messages
• Test server command manually in terminal: npx -y {server_id}
• Ensure environment variables are properly set

Permission Denied Errors

Symptoms: Cannot execute commands, File access denied, Terminal commands blocked

Cause: Roo Code requires explicit permission for file and command operations

Solution:

• Review and approve permission requests when prompted
• Check VS Code workspace trust settings
• Enable necessary permissions in Roo Code settings
• Verify file and folder permissions on your system

API Key or Model Issues

Symptoms: Authentication failed, Model not responding, No AI completions

Cause: AI model API key not configured or invalid

Solution:

• Verify API key is correctly set in Roo Code settings
• Check API key has sufficient credits/quota
• Test with a different AI model provider
• Review Roo Code output panel for API error details

Custom Mode Not Working with MCP

Symptoms: MCP tools not available in custom mode, Mode cannot access server

Cause: Custom mode configuration does not include MCP tool permissions

Solution:

• Edit custom mode configuration to include MCP tools
• Add "Use MCP" to available tools in mode definition
• Ensure mode has appropriate permissions for external tools
• Test with default mode first to verify MCP server works

Extension Conflicts
