Troubleshooting

Common Issues

Servers not showing in :McpHub

Symptoms: Empty server list, Configuration not loaded

Cause: Incorrect configuration file path or JSON syntax error

Solution:

• Verify servers.json exists in ~/.config/mcphub/ or .vscode/mcp.json in project root
• Check JSON syntax for errors (trailing commas, missing quotes)
• Run :checkhealth mcphub to diagnose issues
