Troubleshooting

Nothing showing up in Claude Desktop?

  1. 1. Check if MCP is enabled:

    • Click the 🔌 icon in Claude Desktop, next to the chat box
    • Expand "Installed MCP Servers"
    • You should see your configured servers

  2. 2. Verify your config:

    • From Claude Desktop, go to Claude > Settings…
    • Open the "Developer" tab to see your configuration

  3. 3. Restart Claude Desktop completely:

    • Quit the app (not just close the window)
    • Start it again

MCP or database errors?

Check Claude Desktop's logs:

tail -n 20 -f ~/Library/Logs/Claude/mcp*.log

Look specifically for the MCPHub log file:

tail -f ~/Library/Logs/Claude/mcp-server-mcphub.log
