However, for production deployments, many users need Docker containerization for: + +1. **Isolation**: Containerized MCP servers provide better security and resource isolation +2. **Scalability**: Docker Compose enables easy scaling and load balancing +3. **Production Readiness**: Container orchestration with health checks, restart policies, and monitoring +4. **Environment Consistency**: Consistent deployment across development, staging, and production +5. **Dependency Management**: Self-contained environments with all dependencies + +This proposal bridges the gap between MCPM's excellent client management and Docker's production deployment capabilities. + +## Detailed Design + +### 1. New Command Structure + +Add a new top-level `docker` command group with subcommands: + +```bash +mcpm docker sync PROFILE_NAME # Sync profile to Docker Compose +mcpm docker status # Show Docker integration status +mcpm docker deploy [SERVICES...] # Deploy Docker services +mcpm docker generate PROFILE_NAME # Generate Docker Compose from profile +``` + +### 2. Architecture Components + +#### A. DockerIntegration Class (`mcpm/commands/docker.py`) +- Main orchestrator for Docker operations +- Manages server-to-Docker mappings +- Handles Docker Compose generation and deployment +- Provides status monitoring + +#### B. DockerSyncOperations Class (`mcpm/commands/target_operations/docker_sync.py`) +- Bidirectional sync operations +- Conflict resolution strategies +- Change detection and smart sync +- Integration with existing target operations + +#### C. Enhanced Profile Schema +Future enhancement to add Docker metadata to profiles: +```python +class Profile(BaseModel): + name: str + api_key: Optional[str] + servers: list[ServerConfig] + docker_metadata: Optional[DockerMetadata] = None # New field + +class DockerMetadata(BaseModel): + compose_file: Optional[str] = "docker-compose.yml" + auto_deploy: bool = False + conflict_resolution: str = "profile_wins" + last_sync_hash: Optional[str] = None +``` + +### 3. Server Mapping System + +#### A. MCP Server → Docker Service Mapping +```python +server_mappings = { + 'postgresql': { + 'image': 'postgres:16-alpine', + 'environment': ['POSTGRES_USER=${POSTGRES_USER:-mcpuser}', ...], + 'ports': ['5432:5432'], + 'volumes': ['postgres-data:/var/lib/postgresql/data'], + 'networks': ['mcp-network'], + 'healthcheck': {...} + }, + 'context7': {...}, + 'github': {...}, + 'obsidian': {...} +} +``` + +#### B. Detection Logic +- **Name-based**: Direct matching (postgresql → postgresql service) +- **Package-based**: NPM package detection (@modelcontextprotocol/server-postgres → postgresql) +- **Command-based**: Command line analysis for custom servers + +### 4. Bidirectional Sync + +#### A. Sync Directions +1. **Profile → Docker**: Generate Docker Compose from MCPM profile +2. **Docker → Profile**: Create/update MCPM profile from Docker services +3. **Bidirectional**: Intelligent sync with conflict resolution + +#### B. Conflict Resolution Strategies +- `profile_wins`: MCPM profile takes precedence +- `docker_wins`: Docker Compose takes precedence +- `manual`: Require manual intervention +- `merge`: Intelligent merging (future enhancement) + +#### C. Change Detection +- File hash comparison for Docker Compose files +- Profile modification timestamps +- Service configuration checksums + +### 5. Integration Points + +#### A. Command Registration +Add to `mcpm/cli.py`: +```python +from mcpm.commands import docker +main.add_command(docker.docker, name="docker") +``` + +#### B. Target Operations Extension +Extend existing target operations (`add`, `remove`, `transfer`) to optionally sync with Docker: +```bash +mcpm add postgresql --target %production --sync-docker +mcpm rm postgresql --target %production --sync-docker +``` + +#### C. Router Integration +Future enhancement to add Docker service discovery to the router: +- Health monitoring of containerized servers +- Automatic port mapping +- Load balancing across container replicas + +### 6. Docker Compose Structure + +Generated Docker Compose files include: + +#### A. Standard Networks +```yaml +networks: + mcp-network: + driver: bridge + ipam: + config: + - subnet: 10.200.0.0/16 + mcp-management: + driver: bridge + ipam: + config: + - subnet: 10.201.0.0/16 +``` + +#### B. Service Template +```yaml +services: + postgresql: + image: postgres:16-alpine + container_name: mcp-postgresql + environment: + - POSTGRES_USER=${POSTGRES_USER:-mcpuser} + - POSTGRES_PASSWORD=${POSTGRES_PASSWORD:-password} + - POSTGRES_DB=${POSTGRES_DB:-mcpdb} + ports: + - "5432:5432" + volumes: + - postgres-data:/var/lib/postgresql/data + networks: + - mcp-network + restart: unless-stopped + healthcheck: + test: ["CMD-SHELL", "pg_isready -U ${POSTGRES_USER:-mcpuser}"] + interval: 10s + timeout: 5s + retries: 3 + start_period: 30s +``` + +## Implementation Plan + +### Phase 1: Core Docker Commands (Week 1-2) +- [x] Implement `DockerIntegration` class +- [x] Add `mcpm docker` command group +- [x] Basic profile → Docker sync +- [x] Docker service status monitoring + +### Phase 2: Bidirectional Sync (Week 3-4) +- [x] Implement `DockerSyncOperations` class +- [x] Docker → profile sync +- [x] Conflict resolution strategies +- [ ] Change detection and smart sync + +### Phase 3: Enhanced Integration (Month 2) +- [ ] Extend existing target operations with Docker sync +- [ ] Enhanced profile schema with Docker metadata +- [ ] Router integration for container health monitoring +- [ ] Comprehensive testing and documentation + +### Phase 4: Advanced Features (Month 3+) +- [ ] Multi-environment support (dev/staging/prod) +- [ ] Container scaling and load balancing +- [ ] Advanced conflict resolution (merge strategies) +- [ ] Performance monitoring and metrics + +## Backward Compatibility + +This proposal maintains full backward compatibility: + +1. **Existing Profiles**: All current profiles continue to work unchanged +2. **Existing Commands**: No changes to existing command behavior +3. **Optional Feature**: Docker integration is entirely opt-in +4. **Schema Evolution**: Docker metadata is optional and backward-compatible + +## Testing Strategy + +### Unit Tests +- Server detection and mapping logic +- Docker Compose generation +- Bidirectional sync operations +- Conflict resolution strategies + +### Integration Tests +- End-to-end profile → Docker → profile workflows +- Docker deployment and health checks +- Multi-service synchronization +- Error handling and recovery + +### Compatibility Tests +- Existing MCPM functionality unchanged +- Various Docker environments (local, remote, CI/CD) +- Different MCP server types and configurations + +## Alternatives Considered + +### 1.

a493da2de52219f2a96a0304c66febc6acc3e499 Mon Sep 17 00:00:00 2001 From: Chaz Dinkle Date: Sun, 6 Jul 2025 21:06:52 -0400 Subject: [PATCH 2/2] fix: Address security and logic issues from bot review MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 🔒 Security Improvements: - Remove weak default credentials, require explicit environment variables - Fix Docker network connections to use service names instead of localhost - Add environment variable validation with warnings for missing credentials - Validate required vars: POSTGRES_USER, POSTGRES_PASSWORD, GITHUB_TOKEN, etc. 🐛 Logic Fixes: - Implement proper change detection using file/profile hashes - Replace always-true methods with real MD5-based change tracking - Add robust JSON parsing with error handling for malformed output - Include stderr in subprocess error messages for better debugging 🛠️ Error Handling: - Add graceful handling of malformed JSON in docker-compose output - Enhanced subprocess error reporting with detailed stderr - Better connection string parsing for Docker environment variables ✨ User Experience: - Add consistent -h, --help patterns with examples - Improved CLI documentation and usage examples - Better warning messages for configuration issues 🧪 Testing: - Add 7 new test cases for security and error handling - Test environment variable validation - Test change detection functionality - Test malformed JSON parsing - Total: 28 tests passing (up from 21) Addresses all security concerns and logic issues identified in bot review. Maintains 100% backward compatibility while improving robustness. --- src/mcpm/commands/docker.py | 55 ++++++++- .../commands/target_operations/docker_sync.py | 60 ++++++++-- tests/test_docker_integration.py | 105 ++++++++++++++++++ 3 files changed, 208 insertions(+), 12 deletions(-) diff --git a/src/mcpm/commands/docker.py b/src/mcpm/commands/docker.py index c4309d62..735480cc 100644 --- a/src/mcpm/commands/docker.py +++ b/src/mcpm/commands/docker.py @@ -37,8 +37,8 @@ def __init__(self, compose_file: str = "docker-compose.yml"): 'postgresql': { 'image': 'postgres:16-alpine', 'environment': [ - 'POSTGRES_USER=${POSTGRES_USER:-mcpuser}', - 'POSTGRES_PASSWORD=${POSTGRES_PASSWORD:-password}', + 'POSTGRES_USER=${POSTGRES_USER}', + 'POSTGRES_PASSWORD=${POSTGRES_PASSWORD}', 'POSTGRES_DB=${POSTGRES_DB:-mcpdb}' ], 'ports': ['5432:5432'], @@ -47,7 +47,7 @@ def __init__(self, compose_file: str = "docker-compose.yml"): ], 'networks': ['mcp-network'], 'healthcheck': { - 'test': ['CMD-SHELL', 'pg_isready -U ${POSTGRES_USER:-mcpuser}'], + 'test': ['CMD-SHELL', 'pg_isready -U ${POSTGRES_USER}'], 'interval': '10s', 'timeout': '5s', 'retries': 3, @@ -104,6 +104,13 @@ def __init__(self, compose_file: str = "docker-compose.yml"): self.standard_volumes = { 'postgres-data': {} } + + #
