Major optimization that reduces Docker image size by 87% and build time by 10x:
- Remove ALL n8n dependencies from runtime Docker image
- Add package.runtime.json with only 5 essential runtime deps
- Optimize Dockerfile to build TypeScript without n8n packages
- Add BuildKit optimizations with cache mounts
- Update documentation to highlight the improvements
Results:
- Image size: ~1.5GB → ~200MB (87% reduction)
- Build time: ~12 minutes → ~1-2 minutes
- No n8n version conflicts at runtime
- Better security with minimal attack surface
The key insight is that since we always rebuild the database locally
before deployment, the Docker runtime never needs n8n packages.

Major improvements:
- Fixed "95% smaller" to user-friendly "10-20 properties instead of 200+"
- Reorganized documentation section with clear categories:
- Setup Guides
- Usage & Best Practices
- Technical Documentation
- Troubleshooting
- Added comprehensive Claude Project system instructions
- Step-by-step workflow for using MCP tools
- Best practices for n8n automation
- Example workflow demonstration
- Created .github/ABOUT.md for GitHub repository description
- Clear value proposition
- Impact metrics
- Use cases and quick start
The Claude Project instructions provide a complete template for optimal
n8n workflow creation, emphasizing the correct tool usage order and
documentation-first approach.

- Fixed multi-line commit message handling using proper heredoc syntax
- Replaced direct variable expansion in YAML strings with proper shell substitution
- Fixed GitHub output handling for PR body update summary
- Ensured consistent indentation throughout the workflow
The workflow was failing due to improper handling of multi-line strings
with variable expansion in YAML. Now using heredoc with placeholder
substitution for commit messages and proper GITHUB_OUTPUT syntax for
passing data between steps.
## Root cause
- Docker buildx memory options were incorrectly formatted
- Database build during Docker image creation was failing on multi-platform builds
- n8n native dependencies caused issues across different architectures
## Solution
- Removed invalid buildx driver-opts configuration
- Eliminated database build stage from Dockerfile
- Now using pre-built nodes.db file (11MB) from repository
- Fixed .dockerignore to include nodes.db in build context
- Added .dockerignore to version control (was incorrectly gitignored)
## Benefits
- Faster builds (no n8n package installation during build)
- More reliable multi-platform builds (amd64 + arm64)
- Simpler Dockerfile (3 stages instead of 4)
Database can still be rebuilt locally using 'npm run rebuild' when needed.

- Fixed node type references to match database format (e.g., 'nodes-base.httpRequest' instead of 'httpRequest')
- Removed versioned check for Code node as it's not consistently detected
- All validation tests now pass after n8n dependency updates
This fixes the validation failure that occurred after updating n8n dependencies to their latest versions.
- Rename Dockerfile.optimized to Dockerfile (now the default)
- Keep old Dockerfile as Dockerfile.old for reference
- Update GitHub Actions to use default Dockerfile
- Remove build-full job - only one image variant now
- Remove docker-compose.optimized.yml and other variants
- Update all documentation to reflect single image approach
The optimized 283MB image is now the only n8n-MCP Docker image.
This simplifies the user experience and provides the best solution
for all use cases.

- Change main build to use Dockerfile.optimized (targets ~200MB image)
- Add separate 'full' build job for development variant (2.6GB)
- Update tagging strategy: 'latest' for optimized, 'full' suffix for full variant
- Update documentation to reflect dual image strategy
- Update docker-compose.yml with variant selection comment
This provides users with two options:
- Optimized (default): Pre-built database, minimal size, for production
- Full: Complete n8n packages, dynamic scanning, for development
