CRITICAL HOTFIX: MCP Tools Loading Restored

We sincerely apologize for releasing v10.0.0 with a critical bug that prevented ALL MCP tools from loading in Claude Desktop. This hotfix resolves the issue immediately.

What Was Broken in v10.0.0

• Impact: Complete tool loading failure in Claude Desktop
• Error: NameError: name 'false' is not defined in handle_list_tools()
• Cause: JavaScript-style boolean literals (false/true) used in tool schemas instead of Python booleans (False/True)
• Affected Users: ALL Claude Desktop users attempting to use v10.0.0

What's Fixed in v10.0.1

• ✅ All tool schemas now use proper Python boolean literals (False/True)
• ✅ Affected locations corrected: server_impl.py lines 1446, 1662, 2182, 2380
• ✅ MCP tools now load correctly in Claude Desktop
• ✅ All 12 unified tools are now accessible as intended
• ✅ Commit: 2958aef

Immediate Action Required

If you upgraded to v10.0.0, please upgrade to v10.0.1 immediately:

pip install --upgrade mcp-memory-service

Then restart Claude Desktop to load the fixed server.

Our Apology

We deeply regret this oversight. The bug was introduced during the major API consolidation work in v10.0.0 and was not caught by our testing due to the specific way Claude Desktop processes MCP tool schemas. We have:

1. ✅ Fixed the issue within hours of release
2. ✅ Released this hotfix immediately
3. ✅ Enhanced our test suite to catch similar issues in future releases
4. ✅ Improved our pre-release validation procedures

Thank you for your patience and understanding as we work to make MCP Memory Service more reliable.

For Users on v9.3.1 or Earlier

You are not affected by this bug. You may continue using your current version or upgrade directly to v10.0.1 to benefit from the new API consolidation features:

• 🎯 34 tools → 12 unified tools (64% API simplification)
• 🔄 100% backwards compatible (old tools still work with warnings)
• 🚀 Enhanced capabilities (combined filters, flexible modes)
• 📚 Complete migration guide in docs/MIGRATION.md
