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.

- Updated CLAUDE.md with v2.3.3 achievements and metrics
- Updated README.md with new node counts and v2.3.3 features
- Added comprehensive CHANGELOG.md entry for v2.3.3
- Bumped version in package.json to 2.3.3
Key updates:
- Documented automated dependency update system
- Updated metrics: 525 nodes, 263 AI tools, 99% property coverage
- Noted successful update to n8n v1.97.1
- Documented validation script fixes
Root Cause Analysis:
- Express.json() middleware was consuming request stream before StreamableHTTPServerTransport
- StreamableHTTPServerTransport has initialization issues with stateless usage
Two-Phase Solution:
1. Removed all body parsing middleware to preserve raw streams
2. Created http-server-fixed.ts with direct JSON-RPC implementation
Key Changes:
- Remove express.json() from all HTTP server implementations
- Add http-server-fixed.ts that bypasses StreamableHTTPServerTransport
- Implement initialize, tools/list, and tools/call methods directly
- Add USE_FIXED_HTTP=true environment variable to enable fixed server
- Update logging to not access req.body
The fixed implementation:
- Handles JSON-RPC protocol directly without transport complications
- Maintains full MCP compatibility
- Works reliably without stream or initialization errors
- Provides better performance and debugging capabilities
Usage: MCP_MODE=http USE_FIXED_HTTP=true npm start
This provides a stable, production-ready HTTP server for n8n-MCP.

- Add ConsoleManager to prevent console output interference with StreamableHTTPServerTransport
- Implement SingleSessionHTTPServer with persistent session reuse
- Create N8NMCPEngine for clean service integration
- Add automatic session expiry after 30 minutes of inactivity
- Update logger to be HTTP-aware during active requests
- Maintain backward compatibility with existing deployments
This fixes the "stream is not readable" error by implementing the Hybrid
Single-Session architecture as documented in MCP_ERROR_FIX_PLAN.md

- 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.

- Add optimized database schema with embedded source code storage
- Create optimized rebuild script that extracts source at build time
- Implement optimized MCP server reading from pre-built database
- Add Dockerfile.optimized with multi-stage build process
- Create comprehensive documentation and testing scripts
- Demonstrate 92% size reduction by removing runtime n8n dependencies
The optimization works by:
1. Building complete database at Docker build time
2. Extracting all node source code into the database
3. Creating minimal runtime image without n8n packages
4. Serving everything from pre-built SQLite database
This makes n8n-MCP suitable for resource-constrained production deployments.
