- Remove 5-operation limit from n8n_update_partial_workflow
- Update CHANGELOG.md with version 2.13.1 entry
- Bump version in package.json to 2.13.1
- Remove static version badge from README.md (npm badge remains)
The workflow diff engine now supports unlimited operations per request,
enabling complex workflow refactoring in single API calls.
The 5-operation limit was overly conservative and unnecessary. Analysis showed:
- Workflow is cloned before modifications (no original mutation)
- All operations validated before any are applied (true atomicity)
- First error causes immediate return (no partial state possible)
- Two-pass processing handles dependencies correctly
Changes:
- Remove hard-coded 5-operation limit check from workflow-diff-engine.ts
- Update tool descriptions and documentation to reflect unlimited operations
- Add tests verifying 50 and 100+ operations work successfully
- Add example showing 26 operations in single request
The system already ensures complete transactional integrity regardless of
operation count. Bottleneck is workflow size, not operation count.

- Register n8n_autofix_workflow handler in MCP server
- Export n8nAutofixWorkflowDoc in tool documentation indices
- Use normalizeNodeType utility in workflow validator for consistent type handling
- Add defensive null checks in template sanitizer to prevent runtime errors
- Update workflow validator test to handle new error message formats
These changes complete the webhook autofixer integration, ensuring the tool
is properly exposed through the MCP server and documentation system.

- Add webhook path auto-generation for nodes missing path configuration
- Generates UUID for both 'path' parameter and 'webhookId' field
- Conditionally updates typeVersion to 2.1 only when < 2.1
- High confidence fix (95%) as UUID generation is deterministic
- Fix critical security and performance issues in NodeSimilarityService:
- Replace regex patterns with string-based matching to prevent ReDoS attacks
- Add cache invalidation with version tracking to prevent memory leaks
- Optimize Levenshtein distance algorithm from O(m*n) space to O(n)
- Add early termination for performance improvement
- Extract magic numbers into named constants
- Add comprehensive documentation for n8n_autofix_workflow tool
- Document all fix types including new webhook-missing-path
- Include examples, best practices, and warnings
- Integrate with MCP tool documentation system
- Create node-type-utils for centralized type normalization
- Eliminate code duplication across services
- Consistent handling of package prefixes

- Changed UpdateNodeOperation interface to use 'updates' instead of 'changes'
- Updated UpdateConnectionOperation for consistency
- Fixed implementation in workflow-diff-engine.ts
- Updated Zod schema validation
- Fixed documentation and examples
- Updated tests to match new property name
This resolves GitHub issues #159 and #168 where partial workflow updates
were failing, forcing AI agents to fall back to expensive full updates.

- Changed misleading 'total' field to 'returned' to clarify it's the count in current page
- Added 'hasMore' boolean flag for clear pagination indication
- Added '_note' guidance when more data is available
- Applied same improvements to n8n_list_executions for consistency
Performance improvements:
- Tool now returns only minimal metadata instead of full workflow structure
- Reduced response size by ~95% (from thousands to ~10 tokens per workflow)
- Eliminated token limit errors when listing workflows with many nodes
- Updated descriptions and documentation to clarify minimal response
