v8.18.2 - Critical MCP Retrieve Memory Fix

on GitHub

🐛 Critical Bugfix

Fixed

• MCP Tool Handler Method Name - Fixed critical bug where MCP tool handlers called non-existent retrieve_memory() method
  • Root Cause: Method name mismatch introduced in commit 36e9845 during MemoryService refactoring (Oct 28, 2025)
  • Symptom: 'MemoryService' object has no attribute 'retrieve_memory' error when using MCP retrieve_memory tool
  • Fix: Updated handlers to call correct retrieve_memories() method (plural)
  • Files Modified: server.py (line 2153), mcp_server.py (line 227)
  • Additional: Removed unsupported min_similarity parameter from MCP tool definition
  • Impact: MCP retrieve_memory tool now functions correctly
  • Issue: #207

📦 Installation

pip install --upgrade mcp-memory-service
