This tutorial covers how to add the [Container Use MCP Server](https://container-use.com) as a Goose extension enabling Goose to work in an isolated environment.

## Configuration

:::info
You'll need [Docker](https://www.docker.com/) installed on your system. If you want to use the remote MCP server, you'll also need [Node.js](https://nodejs.org/) installed.

## Example Usage

Here's a simple example of updating a file-based to-do app to use a SQLite database plus full testing - all within an isolated container environment.

#### Prompt

```
Run a container agent to add a feature to save my to-do list data in sqlite, build and run tests, but use a separate Git branch so my main code stays safe.
```

#### Goose Output

```
I'll help you create a container environment to add SQLite functionality to your to-do list application on a separate Git branch. Let me start by creating the environment and examining your current code structure.
─── environment_create | containeruse ──────────────────────────
environment_source: ./examples/todo-list
explanation: ...
title: ...

Now let me set up the environment with the necessary tools and then proceed with the SQLite feature development:
─── environment_config | containeruse ──────────────────────────
config:
base_image: python:3.11-slim
setup_commands:
-
[REDACTED: 63 chars]
-
pip install pytest pytest-cov

environment_id: thankful-whale
environment_source: ./examples/todo-list
explanation: ...

Let me install pytest after the environment is running:

---

Great! I've created a container environment for safely adding SQLite functionality to your to-do list app. Let me first explore the current code structure and then create a new Git branch.

---

Now I'll create the SQLite-based storage implementation. First, let me create a new version of the TaskManager with SQLite support:

## ✅ SQLite Feature Successfully Added!

I've successfully created a container environment and added SQLite functionality to your to-do list application! Here's what was accomplished:

### 🎯 **Features Implemented**

1. **SQLite Database Storage**
- Replaced plain text file storage with SQLite database
- Created proper database schema with auto-incrementing IDs

2. **Enhanced Task Management**
- All original functionality preserved (add, list, mark done/undone, delete, clear)
- Added new **statistics feature** showing completion rates
- Improved task display with database IDs

3. **Two Implementation Versions**
- `taskman_sqlite.py` - Full-featured with Rich UI
- `taskman_sqlite_simple.py` - Simplified without external dependencies

### 🧪 **Testing Completed**

- ✅ Created comprehensive test suite (`test_taskman_sqlite.py`)
- ✅ Built simple test runner (`test_simple.py`)
- ✅ All tests pass successfully
- ✅ Manual testing confirms functionality works perfectly

### 📊 **Live Demo Results**

# Added tasks successfully
✓ Added task: Buy groceries
✓ Added task: Walk the dog

# Listed tasks with SQLite IDs
📋 Task List (SQLite)
# ID Status Task
1 1 ✓ Done Buy groceries
2 2 ○ Todo Walk the dog

# Statistics working
Task Statistics:
Total tasks: 2
Completed: 1
Pending: 1
Completion rate: 50.0%

# Database verified
sqlite3 tasks.db "SELECT * FROM tasks;"
1|Buy groceries|1
2|Walk the dog|0


### 🔒 **Safe Development**

- ✅ Used separate container environment
- ✅ All changes isolated from your main code
- ✅ Original implementation preserved
- ✅ Backward compatibility maintained

### 📁 **Files Created**

- `taskman_sqlite_simple.py` - Main SQLite implementation
- `test_simple.py` - Test suite
- `SQLITE_FEATURE_README.md` - Comprehensive documentation
- `tasks.db` - SQLite database file

The SQLite implementation is fully functional and ready for use! The original file-based version remains untouched, so you can safely evaluate the new SQLite features without any risk to your existing code.
