v8.61.2 - Critical delete_memory KeyError Hotfix

on GitHub

🚨 Critical Hotfix: delete_memory KeyError

This patch release fixes a critical bug in the delete_memory MCP tool introduced during Phase 3 refactoring.

Fixed

• CRITICAL: delete_memory KeyError (#300)
  • Fixed handler attempting to access non-existent 'message' key in response
  • Root cause: Service returns {'success': bool, 'content_hash': str, 'error': str} but handler expected {'message': str}
  • Solution: Updated handle_delete_memory to check result['success'] and use correct response keys
  • Updated MCP tool docstring to document actual return format
  • Validation: Tested delete flow confirms fix works correctly

Impact

• Before: delete_memory tool would crash with KeyError when attempting to delete memories
• After: Tool works correctly, properly handling both success and error cases

Upgrade Recommendation

CRITICAL - Upgrade immediately if you use the delete_memory MCP tool.

pip install --upgrade mcp-memory-service
