MCP implementation of Hanzo capabilities

Hanzo MCP

An implementation of Hanzo capabilities using the Model Context Protocol (MCP).

Overview

This project provides an MCP server that implements Hanzo-like functionality, allowing Claude to directly execute instructions for modifying and improving project files. By leveraging the Model Context Protocol, this implementation enables seamless integration with various MCP clients including Claude Desktop.

Features

• Code Understanding: Analyze and understand codebases through file access and pattern searching
• Code Modification: Make targeted edits to files with proper permission handling
• Enhanced Command Execution: Run commands and scripts in various languages with improved error handling and shell support
• File Operations: Manage files with proper security controls through shell commands
• Code Discovery: Find relevant files and code patterns across your project
• Project Analysis: Understand project structure, dependencies, and frameworks
• Agent Delegation: Delegate complex tasks to specialized sub-agents that can work concurrently
• Multiple LLM Provider Support: Configure any LiteLLM-compatible model for agent operations
• Jupyter Notebook Support: Read and edit Jupyter notebooks with full cell and output handling

Getting Started

Quick Install

# Install using uv
uv pip install hanzo-mcp

# Or using pip
pip install hanzo-mcp

For detailed installation and configuration instructions, please refer to INSTALL.md.

Of course, you can also read USEFUL_PROMPTS for some inspiration on how to use hanzo-mcp.

Security

This implementation follows best practices for securing access to your filesystem:

• Permission prompts for file modifications and command execution
• Restricted access to specified directories only
• Input validation and sanitization
• Proper error handling and reporting

Development

Setup Development Environment

# Clone the repository
git clone https://github.com/hanzoai/mcp.git
cd mcp

# Install Python 3.13 using uv
make install-python

# Setup virtual environment and install dependencies
make setup

# Or install with development dependencies
make install-dev

Testing

# Run tests
make test

# Run tests with coverage
make test-cov

Building and Publishing

# Build package
make build

# Version bumping
make bump-patch    # Increment patch version (0.1.x → 0.1.x+1)
make bump-minor    # Increment minor version (0.x.0 → 0.x+1.0)
make bump-major    # Increment major version (x.0.0 → x+1.0.0)

# Publishing (creates git tag and pushes it to GitHub)
make publish                     # Publish using configured credentials in .pypirc
PYPI_TOKEN=your_token make publish  # Publish with token from environment variable

# Version bump and publish in one step (with automatic git tagging)
make publish-patch  # Bump patch version, publish, and create git tag
make publish-minor  # Bump minor version, publish, and create git tag
make publish-major  # Bump major version, publish, and create git tag

# Publish to Test PyPI
make publish-test
