* fix: use correct MCP SDK API for server capabilities in test getServerVersion() returns Implementation (name/version only), not the full init result. Use client.getServerCapabilities() instead to access server capabilities, fixing the CI typecheck failure. Concieved by Romuald Członkowski - www.aiadvisors.pl/en Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: resolve multiple n8n_update_partial_workflow bugs (#592, #599, #610, #623, #624, #625, #629, #630, #633) Phase 1 - Data loss prevention: - Add missing unary operators (empty, notEmpty, exists, notExists) to sanitizer (#592) - Preserve positional empty arrays in connections during removeNode/cleanStale (#610) - Scope sanitization to modified nodes only, preventing unrelated node corruption - Add empty body {} to activate/deactivate POST calls to fix 415 errors (#633) Phase 2 - Error handling & response clarity: - Serialize Zod errors to readable "path: message" strings (#630) - Add saved:true/false field to all response paths (#625) - Improve updateNode error hint with correct structure example (#623) - Track removed node names for better removeConnection errors (#624) Phase 3 - Connection & type fixes: - Coerce sourceOutput/targetInput to String() consistently (#629) - Accept numeric sourceOutput/targetInput at Zod schema level via transform Phase 4 - Tag operations via dedicated API (#599): - Track tags as tagsToAdd/tagsToRemove instead of mutating workflow.tags - Orchestrate tag creation and association via listTags/createTag/updateWorkflowTags - Reconcile conflicting add/remove for same tag (last operation wins) - Tag failures produce warnings, not hard errors Conceived by Romuald Członkowski - www.aiadvisors.pl/en Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * docs: add v2.37.0 changelog entry Conceived by Romuald Członkowski - www.aiadvisors.pl/en Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: resolve pre-existing integration test failures in CI - Create new MCP Server instance per connection in test helpers (SDK 1.27+ requires separate Protocol instance per connection) - Normalize database paths with path.resolve() in shared-database singleton to prevent path mismatch errors across test files - Add no-op catch handler to deferred initialization promise in server.ts to prevent unhandled rejection warnings - Properly call mcpServer.shutdown() in test helper close() to release shared database references Conceived by Romuald Członkowski - www.aiadvisors.pl/en Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
