MC - Monadical Container Tool

MC (Monadical Container) is a command-line tool for managing ephemeral containers that run AI tools and development environments. It works with both local Docker and a dedicated remote web service that manages containers in a Docker-in-Docker (DinD) environment.

Requirements

• uv

Installation

# Clone the repository
git clone https://github.com/monadical/mcontainer.git

# Install the tool locally
# (with editable, so you can update the code and work with it)
cd mcontainer
uv tool install --with-editable . .

# Then you could use the tool as `mc`
mc --help

Basic Usage

# Create a new session with the default driver
# mc create session -- is the full command
mc

# List all active sessions
mc session list

# Connect to a specific session
mc session connect SESSION_ID

# Close a session when done
mc session close SESSION_ID

# Create a session with a specific driver
mc session create --driver goose

# Create a session with environment variables
mc session create -e VAR1=value1 -e VAR2=value2

# Mount custom volumes (similar to Docker's -v flag)
mc session create -v /local/path:/container/path
mc session create -v ~/data:/data -v ./configs:/etc/app/config

# Shorthand for creating a session with a project repository
mc github.com/username/repo

Driver Management

MC includes a driver management system that allows you to build, manage, and use Docker images for different AI tools:

# List available drivers
mc driver list

# Get detailed information about a driver
mc driver info goose

# Build a driver image
mc driver build goose

# Build and push a driver image
mc driver build goose --push

Drivers are defined in the mcontainer/drivers/ directory, with each subdirectory containing:

• Dockerfile: Docker image definition
• entrypoint.sh: Container entrypoint script
• mc-init.sh: Standardized initialization script
• mc-driver.yaml: Driver metadata and configuration
• README.md: Driver documentation

MC automatically discovers and loads driver definitions from the YAML files.

Development

# Run the tests
uv run -m pytest

# Run linting
uvx ruff check .

# Run type checking
uvx mypy .

# Format code
uvx ruff format .

Configuration

MC supports user-specific configuration via a YAML file located at ~/.config/mc/config.yaml. This allows you to set default values and configure service credentials.

Managing Configuration

# View all configuration
mc config list

# Get a specific configuration value
mc config get langfuse.url

# Set configuration values
mc config set langfuse.url "https://cloud.langfuse.com"
mc config set langfuse.public_key "pk-lf-..."
mc config set langfuse.secret_key "sk-lf-..."

# Set API keys for various services
mc config set openai.api_key "sk-..."
mc config set anthropic.api_key "sk-ant-..."

# Reset configuration to defaults
mc config reset

Service Credentials

Service credentials like API keys configured in ~/.config/mc/config.yaml are automatically passed to containers as environment variables:

Config Setting	Environment Variable
langfuse.url	LANGFUSE_URL
langfuse.public_key	LANGFUSE_INIT_PROJECT_PUBLIC_KEY
langfuse.secret_key	LANGFUSE_INIT_PROJECT_SECRET_KEY
openai.api_key	OPENAI_API_KEY
anthropic.api_key	ANTHROPIC_API_KEY
openrouter.api_key	OPENROUTER_API_KEY
