+# You can manage this file using the 'go-go-mcp config' commands:
+# - edit: Edit this file in your default editor
+# - list-profiles: List all available profiles
+# - show-profile: Show full configuration of a profile
+# - add-tool: Add tool directory or file to a profile
+# - add-profile: Create a new profile
+# - duplicate-profile: Create a new profile by duplicating an existing one
+# - set-default-profile: Set the default profile
