Release Notes - hanzo-mcp v0.6.13

🎉 Successfully Published to PyPI

Package: https://pypi.org/project/hanzo-mcp/0.6.13/

🐛 Critical Bug Fix

Context Parameter Issue (FIXED)

Problem: MCP tools were failing when called externally through the protocol because the Context parameter was being passed as a string (e.g., "{}") instead of a proper MCPContext object
Solution: Implemented automatic context normalization at the server level using decorators

🏗️ Architecture Improvements

Uniform Context Handling

Created @with_context_normalization decorator that automatically handles various context types
Introduced EnhancedFastMCP server that applies context normalization to ALL tools automatically
No more copy-paste code - single point of implementation
Works transparently for both internal and external calls

Key Files Added

hanzo_mcp/tools/common/decorators.py - Core decorator implementation
hanzo_mcp/server_enhanced.py - Enhanced server with automatic normalization
hanzo_mcp/tools/common/enhanced_base.py - Enhanced base classes for tools

🧹 Major Cleanup

Removed Files (30+)

All test files moved from root to tests/ directory
Removed temporary scripts and backup files
Cleaned up unified tool implementations that were causing issues
Removed icon creation utilities and demo files

Project Structure

Clean separation of concerns
All tests properly organized in tests/
No duplicate or temporary files
Proper modular architecture

💻 Installation

pip install --upgrade hanzo-mcp==0.6.13

🔄 Migration

No changes required for existing users. The context normalization is applied automatically and transparently.

✅ What This Fixes

Tools now properly handle:

Standard MCPContext objects ✓
String contexts (e.g., "{}") ✓
None contexts ✓
Dictionary contexts ✓

This ensures MCP tools work reliably whether called internally by the server or externally through the MCP protocol.
