- **MCP Server** (`hanzo-mcp`) - Model Context Protocol server with 30+ tools for AI code assistants
- **Tool Packages** (`hanzo-tools-*`) - Modular tool packages for file operations, shell commands, browser automation, and more

## Installation

=== "Full Install"
    ```bash
    pip install hanzo-mcp[tools-all]
    ```

=== "Agent SDK Only"
    ```bash
    pip install hanzo-agent
    ```

=== "Using uv"
    ```bash
    uv pip install hanzo-mcp
    ```

## Quick Start

### Using with Claude Code

The easiest way to use Hanzo MCP is with Claude Code:

```bash
# Install globally
uvx hanzo-mcp

# Or run directly
uvx hanzo-mcp --transport stdio
```

### Agent SDK Example

```python
from agents import Agent, Runner

agent = Agent(
    name="assistant",
    instructions="You are a helpful assistant."
)

result = Runner.run_sync(agent, "Hello!")
print(result.final_output)
```

### MCP Tools Example

```python
from hanzo_mcp import create_mcp_server

# Create server with all tools
server = create_mcp_server()
server.run()
```

### Auto-Backgrounding

Long-running commands automatically background after 30 seconds:

```python
# This will auto-background if it takes too long
cmd("npm install")

# Check status
ps()  # List all background processes
ps(logs="cmd_xxx")  # View output
ps(kill="cmd_xxx")  # Stop process
```
