📋 MCP Setup Guide: See MCP_SERVERS.md for customizing or adding more MCP servers

This is a complete starter pack for autonomous AI development.

• Complete AI coding agent setup with Claude Code in an isolated Docker container
• Pre-configured MCP servers for maximum coding productivity:
  • Serena - Advanced coding agent toolkit with project indexing and symbol manipulation
  • Context7 - Pulls up-to-date, version-specific documentation and code examples straight from the source into your prompt
  • Twilio - SMS notifications when long-running tasks complete (perfect for >10min jobs)
• Persistent conversation history - Resumes from where you left off, even after crashes
• Remote work notifications - Get pinged via SMS when tasks finish, so you can step away from your monitor
• Simple one-command setup and usage - Zero friction set up for plug and play integration with existing cc workflows.
• Fully customizable - Modify the can modify the files at ~/.claude-docker for custom slash commands, settings and claude.md files.

# 0. Assumes you claude-code and docker already installed.

# 1. Clone and enter directory
git clone https://github.com/VishalJ99/claude-docker.git
cd claude-docker

# 2. Setup environment
cp .env.example .env
nano .env  # Add your API keys (see below)

# 3. Install
./scripts/install.sh

# 4. Run from any project
cd ~/your-project
claude-docker

# Optional: Set up SSH keys for git push (see Prerequisites section)
# The script will show setup instructions if keys are missing

⚠️ IMPORTANT: Complete these steps BEFORE using claude-docker:

You must authenticate Claude Code on your host system first:

# Install Claude Code globally
npm install -g @anthropic-ai/claude-code

# Run and complete authentication
claude

# Verify authentication files exist
ls ~/.claude.json ~/.claude/

📖 Full Claude Code Setup Guide: https://docs.anthropic.com/en/docs/claude-code

• Docker Desktop: https://docs.docker.com/get-docker/
• Ensure Docker daemon is running before proceeding

Git configuration is automatically loaded from your host system during Docker build:

• Make sure you have configured git on your host system first:

  git config --global user.name "Your Name"
  git config --global user.email "[email protected]"

• Important: Claude Docker will commit to your current branch - make sure you're on the correct branch before starting

Claude Docker uses dedicated SSH keys (separate from your main SSH keys for security):

Setup SSH keys:

# 1. Create directory for Claude Docker SSH keys
mkdir -p ~/.claude-docker/ssh

# 2. Generate SSH key for Claude Docker
ssh-keygen -t rsa -b 4096 -f ~/.claude-docker/ssh/id_rsa -N ''

# 3. Add public key to GitHub
cat ~/.claude-docker/ssh/id_rsa.pub
# Copy output and add to: GitHub → Settings → SSH and GPG keys → New SSH key

# 4. Test connection
ssh -T [email protected] -i ~/.claude-docker/ssh/id_rsa

Why separate SSH keys?

• ✅ Security Isolation: Claude can't access or modify your personal SSH keys, config, or known_hosts
• ✅ SSH State Persistence: The SSH directory is mounted at runtime.
• ✅ Easy Revocation: Delete ~/.claude-docker/ssh/ to instantly revoke Claude's git access
• ✅ Clean Audit Trail: All Claude SSH activity is isolated and easily traceable

Technical Note: We mount the SSH directory rather than copying keys because SSH operations modify several files (known_hosts, connection state) that must persist between container sessions for a smooth user experience.

If you want SMS notifications when tasks complete:

• Create free trial account: https://www.twilio.com/docs/usage/tutorials/how-to-use-your-free-trial-account
• Get your Account SID and Auth Token from the Twilio Console
• Get a phone number for sending SMS

The Docker container needs your existing Claude authentication to function. This approach:

• ✅ Uses your existing Claude subscription/API access
• ✅ Maintains secure credential handling
• ✅ Enables persistent authentication across container restarts

# SMS notifications (highly recommended!)
# Perfect for long-running tasks - step away and get notified when done
TWILIO_ACCOUNT_SID=your_twilio_sid  
TWILIO_AUTH_TOKEN=your_twilio_auth_token
TWILIO_FROM_NUMBER=+1234567890
TWILIO_TO_NUMBER=+0987654321

# Optional - Custom conda paths
CONDA_PREFIX=/path/to/your/conda
CONDA_EXTRA_DIRS="/path/to/envs /path/to/pkgs"

# Optional - System packages
SYSTEM_PACKAGES="libopenslide0 libgdal-dev"

⚠️ Security Note: Credentials are baked into the Docker image. Keep your image secure!

• Claude runs with --dangerously-skip-permissions for complete access
• Can read, write, execute, and modify any files in your project
• No permission prompts or restrictions

• Easy installation of any MCP server through mcp-servers.txt
• Automatic environment variable handling for MCP servers requiring API keys
• Pre-configured popular servers (Twilio, GitHub, filesystem, browser automation)
• See MCP_SERVERS.md for full setup guide

• Automatic SMS via Twilio when Claude completes tasks
• Configurable via MCP integration
• Optional - works without if Twilio not configured

• Has access to your conda envs so do not need to add build instructions to the Dockerfile
• Supports custom conda installation directories (ideal for academic/lab environments where home is quota'd)

• Login once, use forever - authentication tokens persist across sessions
• Automatic UID/GID mapping ensures perfect file permissions between host and container
• Loads history from previous chats in a given project.

• Prompt engineered to generate task_log.md documenting agent's execution process
• Stores assumptions, insights, and challenges encountered
• Acts as a simple summary to quickly understand what the agent accomplished

• Each session runs in fresh Docker container
• Only current working directory mounted (along with conda directories specified in .env).

During build, the .env file from the claude-docker repository directory is baked into the image:

• Credentials are embedded at /app/.env inside the container
• No need to manage .env files in each project
• The image contains everything needed to run
• Important: After updating .env, you must rebuild the image with claude-docker --rebuild

The setup creates ~/.claude-docker/ in your home directory with:

• claude-home/ - Persistent Claude authentication and settings
• ssh/ - Directory where claude-dockers private ssh key and known hosts file is stored.

During installation (install.sh), all contents from the project's .claude/ directory are copied to ~/.claude-docker/claude-home/ as template/base settings. This includes:

• settings.json - Default Claude Code settings with MCP configuration
• CLAUDE.md - Default instructions and protocols
• commands/ - Slash commands (if any)
• Any other configuration files

To modify these settings:

• Recommended: Directly edit files in ~/.claude-docker/claude-home/
• Alternative: Modify .claude/ in this repository and re-run install.sh

All changes to ~/.claude-docker/claude-home/ persist across container sessions.

Each project gets:

• .claude/settings.json - Claude Code settings with MCP
• .claude/CLAUDE.md - Project-specific instructions (if you create one)

Claude Docker supports several command-line flags for different use cases:

claude-docker                    # Start Claude in current directory
claude-docker --continue         # Resume previous conversation in this directory
claude-docker --rebuild          # Force rebuild Docker image
claude-docker --rebuild --no-cache  # Rebuild without using Docker cache

You can also set defaults in your .env file:

DOCKER_MEMORY_LIMIT=8g          # Default memory limit
DOCKER_GPU_ACCESS=all           # Default GPU access

# Resume work with 16GB memory limit
claude-docker --continue --memory 16g

# Rebuild after updating .env file
claude-docker --rebuild

# Use GPU for ML tasks
claude-docker --gpus all

The Docker image is built only once when you first run claude-docker. To force a rebuild:

# Force rebuild (uses cache)
claude-docker --rebuild

# Force rebuild without cache
claude-docker --rebuild --no-cache

Rebuild when you:

• Update your .env file with new credentials
• Update the Claude Docker repository
• Change system packages in .env

For custom conda installations (common in academic/lab environments), add these to your .env file:

# Main conda installation
CONDA_PREFIX=/vol/lab/username/miniconda3

# Additional conda directories (space-separated)
CONDA_EXTRA_DIRS="/vol/lab/username/.conda/envs /vol/lab/username/conda_envs /vol/lab/username/.conda/pkgs /vol/lab/username/conda_pkgs"

How it works:

• CONDA_PREFIX: Mounts your conda installation to the same path in container
• CONDA_EXTRA_DIRS: Mounts additional directories and automatically configures conda

Automatic Detection:

• Paths containing *env* → Added to CONDA_ENVS_DIRS (conda environment search)
• Paths containing *pkg* → Added to CONDA_PKGS_DIRS (package cache search)

Result: All your conda environments and packages work exactly as they do on your host system.

For scientific computing packages that require system libraries, add them to your .env file:

# Install OpenSlide for medical imaging
SYSTEM_PACKAGES="libopenslide0"

# Install multiple packages (space-separated)
SYSTEM_PACKAGES="libopenslide0 libgdal-dev libproj-dev libopencv-dev"

Note: Adding system packages requires rebuilding the Docker image (docker rmi claude-docker:latest).

We provide a different approach than Anthropic's official .devcontainer, optimized for autonomous task execution:

Note: Network firewall functionality similar to Anthropic's implementation is our next planned feature.

Phase 2 - Security Enhancements:

• Network firewall to whitelist specific domains (similar to Anthropic's DevContainer)
• Shell history persistence between sessions
• Additional security features
