v8.19.1 - Critical MCP Tool Fixes

on GitHub

Fixed

• Critical MCP Tool Regressions (Issue #211) - Two core MCP tools broken in v8.19.0
  • retrieve_memory: Fixed parameter error where unsupported 'tags' parameter was passed to storage.retrieve()
    • Removed unsupported parameters from storage call
    • Implemented post-retrieval filtering in MemoryService
    • File: src/mcp_memory_service/services/memory_service.py
  • search_by_tag: Fixed type error where code assumed created_at was always string
    • Added type checking for both float (timestamp) and string (ISO format)
    • Uses datetime.fromtimestamp() for floats, datetime.fromisoformat() for strings
    • Files: src/mcp_memory_service/server.py (handle_search_by_tag, handle_retrieve_memory)
  • Impact: Both tools now work correctly with hybrid storage backend
  • Root Cause: v8.19.0 refactoring introduced incompatibilities with hybrid storage

Upgrade Instructions

Users on v8.19.0 should restart their MCP server (/mcp command or restart Claude Desktop) after updating to pick up the fixes.
