- Update N8N_DEPLOYMENT.md to recommend test-n8n-integration.sh
- Remove outdated test-n8n-mode.sh and related files
- The integration test script properly tests full n8n integration with correct protocol version (2024-11-05)
- Removed scripts: test-n8n-mode.sh, test-n8n-mode.ts, debug-n8n-mode.js

- Improved GitHub Actions test to verify N8N_MODE environment variable
- Added explanatory comment in docker-compose.n8n.yml
- Added Docker Build Changes section to deployment documentation
- Explains the consolidation benefits and rationale for users
- 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
- Create missing v2.9.1 git tag to trigger Docker builds
- Fix GitHub Actions workflow with proper environment variables
- Add comprehensive deployment documentation updates:
* Add missing MCP_MODE=http environment variable requirement
* Clarify Server URL must include /mcp endpoint
* Add complete environment variables reference table
* Update all Docker examples with proper variable configuration
* Add version compatibility warnings for pre-built images
* Document build-from-source as recommended approach
* Add comprehensive troubleshooting section with common issues
* Include systematic debugging steps and diagnostic commands
- Optimize package.runtime.json dependencies for Docker builds
- Ensure both MCP_AUTH_TOKEN and AUTH_TOKEN use same value
