+## [1.0.4] - 2025-01-16
+
+### Fixed
+- Fixed tool wrappers to properly call underlying VultrDNSServer methods instead of trying to call FunctionResource objects
+- Resolved "FunctionResource object is not callable" error in Claude Desktop
+- Tool wrappers now directly call `vultr_client.list_domains()`, `vultr_client.get_domain()`, etc.
+
+### Technical
+- Changed tool wrapper implementation from calling resource functions to calling the underlying client methods
+- Maintains functionality while fixing the callable object error
+
 ## [1.0.3] - 2025-01-16
 
 ### Added
