`settings-write`: Modify non-critical settings +- `settings-write-critical`: Modify critical settings (network, security) +- `settings-schema`: Access to settings schema for UI generation + +**Rate Limiting:** Maximum 50 setting changes per 5 minutes per user + +**Sensitive Settings:** Automatically masked unless explicitly requested with appropriate permissions + +For detailed security configuration, see [settings-security.md](settings-security.md). + +### dumpsettings + +Export all current settings to JSON format with optional encryption. + +**Syntax:** `dumpsettings ( "category"

"block_creation", "network", "gui") +- `include_sensitive` (boolean, optional, default=false): Include sensitive settings (requires settings-read-sensitive permission) +- `encrypt_password` (string,
