MCP-Compose

A comprehensive orchestration tool for managing Model Context Protocol (MCP) servers with container and proxy capabilities. MCP-Compose provides a Docker Compose-style interface for deploying, configuring, and managing multiple MCP servers through a unified HTTP proxy.

MCP-Compose Demo

Overview

MCP-Compose bridges the gap between traditional MCP STDIO servers and modern HTTP-based architectures. It combines the simplicity of Docker Compose configuration with robust MCP protocol support, enabling seamless integration with clients like Claude Desktop, OpenWebUI, and custom applications.

Security Notice

⚠️ CRITICAL SECURITY REQUIREMENTS ⚠️

Before using MCP-Compose, please review these security requirements:

Never commit secrets to version control: All API keys, passwords, and tokens must be stored in environment variables
Use strong credentials: Generate secure random strings for all API keys and passwords
Follow the principle of least privilege: Run containers as non-root users and drop unnecessary capabilities
Use the provided security templates: See mcp-compose_example.yaml for secure configuration patterns

Required Environment Variables

Copy .env.example to .env and configure:

# Core authentication
MCP_API_KEY=your-secure-random-api-key-here
POSTGRES_PASSWORD=your-secure-database-password

# Optional external services
GITHUB_TOKEN=ghp_your-github-token-here
OPENROUTER_API_KEY=sk-or-v1-your-openrouter-api-key-here
OAUTH_CLIENT_SECRET=your-oauth-client-secret-here

Generate secure keys:

# Generate a secure API key
openssl rand -hex 32

# Or using /dev/urandom
head -c 32 /dev/urandom | base64

Quick Start

1. Minimal Configuration (30 seconds)

Create a mcp-compose.yaml file:

version: '1'

servers:
  filesystem:
    image: "mcp/filesystem:latest"
    capabilities: [resources, tools]

Run with:

export MCP_API_KEY="your-secure-key-here"
./mcp-compose up
./mcp-compose proxy --port 9876

Your MCP servers are now available at http://localhost:9876!

2. Basic Configuration (3 servers)

For a more complete setup with file access, memory, and search:

version: '1'

# Simple authentication
proxy_auth:
  enabled: true
  api_key: "${MCP_API_KEY}"

servers:
  # File system access
  filesystem:
    image: "mcp/filesystem:latest"
    capabilities: [resources, tools]
    volumes:
      - "${HOME}/Documents:/workspace:ro"
    
  # Persistent memory/notes
  memory:
    image: "mcp/memory:latest"
    capabilities: [tools, resources]
    env:
      DATABASE_URL: "sqlite:///data/memory.db"
    volumes:
      - "mcp-memory-data:/data"

  # Web search
  search:
    image: "mcp/search:latest"
    capabilities: [tools]
    env:
      SEARCH_ENGINE: "duckduckgo"

volumes:
  mcp-memory-data:
    driver: local

Enterprise Setup

For production deployments with OAuth, audit logging, monitoring, and advanced security, see mcp-compose-advanced.yaml.

Step-by-Step Tutorial

1. First Time Setup (5 minutes)

# 1. Install mcp-compose (see Installation section above)

# 2. Create your first configuration
cat > mcp-compose.yaml << 'EOF'
version: '1'
servers:
  filesystem:
    image: "mcp/filesystem:latest"
    capabilities: [resources, tools]
EOF

# 3. Set your API key
export MCP_API_KEY=$(openssl rand -hex 32)
echo "Your API key: $MCP_API_KEY"

# 4. Start the servers
./mcp-compose up

# 5. Start the proxy in another terminal
./mcp-compose proxy --port 9876 --api-key "$MCP_API_KEY"

Your MCP servers are now running! Test with:

curl -H "Authorization: Bearer $MCP_API_KEY" http://localhost:9876/api/servers

2. Adding More Servers (2 minutes)

# Stop current setup
./mcp-compose down

# Update configuration to add memory and search
cat > mcp-compose.yaml << 'EOF'
version: '1'

proxy_auth:
  enabled: true
  api_key: "${MCP_API_KEY}"

servers:
  filesystem:
    image: "mcp/filesystem:latest"
    capabilities: [resources, tools]
    volumes:
      - "${HOME}/Documents:/workspace:ro"
  
  memory:
    image: "mcp/memory:latest"
    capabilities: [tools, resources]
    env:
      DATABASE_URL: "sqlite:///data/memory.db"
    volumes:

  search:
    image: "mcp/search:latest"
    capabilities: [tools]

volumes:
  mcp-memory:
    driver: local
EOF

# Restart with new configuration
./mcp-compose up
./mcp-compose proxy --port 9876

3. Connect to Claude Desktop (3 minutes)

# Generate Claude Desktop configuration
./mcp-compose create-config --type claude --output ./claude-config

# Copy the generated config to Claude Desktop settings
# Location varies by OS:
# - macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
# - Linux: ~/.config/Claude/claude_desktop_config.json
# - Windows: %APPDATA%\Claude\claude_desktop_config.json

Migration Guides

From Individual MCP Servers

If you're currently running individual MCP servers, migration is straightforward:

Before (individual servers):

npx @modelcontextprotocol/server-filesystem /path/to/files
npx @modelcontextprotocol/server-memory

After (mcp-compose):

version: '1'
servers:
  filesystem:
    image: "mcp/filesystem:latest"
    capabilities: [resources, tools]
    volumes:
      - "/path/to/files:/workspace:ro"
  
  memory:
    image: "mcp/memory:latest"
    capabilities: [tools, resources]

From Docker Compose

If you're already using Docker Compose for MCP servers:

Before (docker-compose.yml):

version: '3.8'
services:
  mcp-filesystem:
    image: mcp/filesystem
    ports:
      - "3000:3000"

After (mcp-compose.yaml):

version: '1'
servers:
  filesystem:
    image: "mcp/filesystem:latest"
    capabilities: [resources, tools]

Benefits of migrating:

✅ Built-in MCP protocol support
✅ Automatic service discovery
✅ Unified HTTP proxy
✅ Claude Desktop integration
✅ Health monitoring and restarts

From Manual Configuration

Before (manual Claude Desktop config):

{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": ["@modelcontextprotocol/server-filesystem", "/path"],
      "env": {}
    }
  }
}

After (with mcp-compose):

Create mcp-compose.yaml (see examples above)
Run ./mcp-compose create-config --type claude
Replace your Claude Desktop config with the generated one

Authentication Examples

Basic API Key (Recommended for getting started)

version: '1'

proxy_auth:
  enabled: true
  api_key: "${MCP_API_KEY}"  # Set via environment variable

servers:
  filesystem:
    image: "mcp/filesystem:latest"
    capabilities: [resources, tools]

No Authentication (Development only)

version: '1'

# No proxy_auth section = no authentication required

servers:
  filesystem:
    image: "mcp/filesystem:latest"
    capabilities: [resources, tools]

⚠️ Never use no authentication in production!

Enterprise OAuth (Advanced)

For OAuth 2.1, RBAC, audit logging, and enterprise features, see mcp-compose-advanced.yaml.

Client Integration

Claude Desktop

# Generate configuration
./mcp-compose create-config --type claude --output ./claude-config

# Your servers will be available as:
# - http://localhost:9876/filesystem
# - http://localhost:9876/memory  
# - http://localhost:9876/search

OpenWebUI

Each server provides its own OpenAPI endpoint:

# Filesystem server API docs
curl http://localhost:9876/filesystem/openapi.json

# Memory server API docs  
curl http://localhost:9876/memory/openapi.json

Custom Clients

Direct HTTP API access:

# List available tools
curl -H "Authorization: Bearer $MCP_API_KEY" \
  http://localhost:9876/filesystem -X POST \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

# Call a tool
curl -H "Authorization: Bearer $MCP_API_KEY" \
  http://localhost:9876/filesystem -X POST \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"read_file","arguments":{"path":"/workspace/README.md"}}}'

Troubleshooting

Common Issues

"Server not found" error:

# Check if servers are running
./mcp-compose ls

# Check logs for errors
./mcp-compose logs filesystem

"Connection refused" error:

# Ensure proxy is running
./mcp-compose proxy --port 9876

# Check if port is already in use
lsof -i :9876

Authentication errors:

# Verify API key is set
echo $MCP_API_KEY

# Check proxy authentication config
grep -A5 "proxy_auth:" mcp-compose.yaml

Debug Mode

# Enable debug logging
export MCP_LOG_LEVEL=debug
./mcp-compose up

# View detailed proxy logs
./mcp-compose proxy --port 9876 --debug

Performance Tuning

# Add connection timeouts (optional)
connections:
  default:
    timeouts:
      connect: "10s"
      read: "30s" 
      write: "30s"
      idle: "60s"
