Updated the Dynamic Client Registration (DCR) handler to comply with RFC 7591 by making the refresh_token grant type optional. Previously, the handler incorrectly required both authorization_code and refresh_token grant types, which was unnecessarily restrictive and non-compliant with the RFC. Changes: - Modified grant_types validation to only require authorization_code - Updated error message to reflect the new requirement - Renamed test to test_client_registration_with_authorization_code_only - Added test for missing authorization_code (now the true error case) - Updated test assertions to match new validation behavior This change improves RFC 7591 compliance and provides clients with greater flexibility in their registration options. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> Github-Issue: modelcontextprotocol#1650
