- Research proved n8n packages are NOT required at runtime for N8N_MODE
- The 'n8n' CMD argument was vestigial and completely ignored by code
- N8N_MODE only affects protocol negotiation, not runtime functionality
- Standard Dockerfile works perfectly with N8N_MODE=true
Benefits:
- Eliminates 500MB+ of unnecessary n8n packages from Docker images
- Reduces build time from 8+ minutes to 1-2 minutes
- Simplifies maintenance with single Dockerfile
- Improves CI/CD reliability
Updated:
- Removed Dockerfile.n8n
- Updated GitHub Actions to use standard Dockerfile
- Fixed docker-compose.n8n.yml to use standard Dockerfile
- Added missing MCP_MODE=http and AUTH_TOKEN env vars
- Updated all documentation references
