- Normalize name→nodeName and id→nodeId for node-targeting operations in
the Zod schema transform, so LLMs using natural field names no longer
get "Node not found" errors
- Replace hardcoded ALL_CONNECTION_TYPES with dynamic iteration so AI
sub-nodes (ai_outputParser, ai_document, ai_textSplitter, etc.) are
not flagged as disconnected during save
- Add .catchall() to workflowConnectionSchema and extend connection
reference validation to cover all connection types, not just main
- Fix filterOperationsByFixes ID-vs-name mismatch: typeversion-upgrade
operations now include nodeName alongside nodeId, and the filter checks
both fields

* 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

* fix: critical memory leak from per-session database connections (#542)
Each MCP session was creating its own database connection (~900MB),

Changes:
- Add SharedDatabase singleton pattern - all sessions share ONE connection

- Add eager cleanup for reconnecting instances
- Fix telemetry event listener leak

* fix: resolve test failures from shared database race conditions
- Fix `shutdown()` to respect shared database pattern (was directly closing)
- Add `await this.initialized` in both `close()` and `shutdown()` to prevent
race condition where cleanup runs while initialization is in progress
- Add double-shutdown protection with `isShutdown` flag
- Export `SharedDatabaseState` type for proper typing
- Include error details in debug logs
- Add MCP server close to `shutdown()` for consistency with `close()`
- Null out `earlyLogger` in `shutdown()` for consistency
The CI test failure "The database connection is not open" was caused by:
1. `shutdown()` directly calling `this.db.close()` which closed the SHARED
database connection, breaking subsequent tests
2. Race condition where `shutdown()` ran before initialization completed

When SSE sessions are recreated every 5 minutes, the old session's MCP
server was not being closed, causing:

- Database connections remaining open
- Cached data (~50-100MB per session) persisting in memory

Docker images were built with stale package.runtime.json (v2.29.5)
while npm package was at v2.33.0. This was caused by the build-docker
job not syncing the version before building, while publish-npm did.
Changes:
- Add "Sync runtime version" step to release.yml build-docker job
- Add "Sync runtime version" step to docker-build.yml build job
- Add "Sync runtime version" step to docker-build.yml build-railway job
- Bump version to 2.33.1 to trigger release with fix
The sync uses a lightweight Node.js one-liner (no npm install needed)
to update package.runtime.json version from package.json before
Docker builds.

* fix: use lowercase for community node names to match n8n convention
Community nodes in n8n use lowercase node class names (e.g., chatwoot
not Chatwoot). The extractNodeNameFromPackage method was incorrectly
capitalizing node names, causing validation failures.
Changes:
- Fix extractNodeNameFromPackage to use lowercase instead of capitalizing
- Add case-insensitive fallback in getNode for robustness
- Update tests to expect lowercase node names
- Bump version to 2.32.1
Fixes the case sensitivity bug where MCP stored Chatwoot but n8n

* feat: add community nodes support (Issues #23, #490)
Add comprehensive support for n8n community nodes, expanding the node
database from 537 core nodes to 1,084 total (537 core + 547 community).
New Features:
- 547 community nodes indexed (301 verified + 246 npm packages)
- `source` filter for search_nodes: all, core, community, verified
- Community metadata: isCommunity, isVerified, authorName, npmDownloads
- Full schema support for verified nodes (no parsing needed)
Data Sources:
- Verified nodes from n8n Strapi API (api.n8n.io)
- Popular npm packages (keyword: n8n-community-node-package)
CLI Commands:
- npm run fetch:community (full rebuild)
- npm run fetch:community:verified (fast, verified only)
- npm run fetch:community:update (incremental)

When n8n connects any node to an AI Agent's tool slot, it creates a
dynamic Tool variant at runtime (e.g., googleDrive → googleDriveTool).
These don't exist in npm packages, causing false "unknown node type"

check if the base node exists. If yes, treat as valid with warning.
Changes:
- workflow-validator.ts: Add INFERRED_TOOL_VARIANT logic
- node-similarity-service.ts: Add 98% confidence for valid Tool variants

* fix: deprecate USE_FIXED_HTTP for SSE streaming support (Issue #524)
The fixed HTTP implementation does not support SSE streaming required
by clients like OpenAI Codex. This commit deprecates USE_FIXED_HTTP
and makes SingleSessionHTTPServer the default.
Changes:
- Add deprecation warnings in src/mcp/index.ts and src/http-server.ts
- Remove USE_FIXED_HTTP from docker-compose.yml and Dockerfile.railway
- Update .env.example with deprecation notice
- Rename npm script to start:http:fixed:deprecated
- Update all documentation to remove USE_FIXED_HTTP references
- Mark test case as deprecated
Users should unset USE_FIXED_HTTP to use the modern SingleSessionHTTPServer
which supports both JSON-RPC and SSE streaming.

Fixed a critical bug where workflow mutation data was corrupted during
serialization to Supabase. The recursive toSnakeCase() function was
converting nested workflow data, mangling:
- Connection keys (node names like "Webhook" → "_webhook")
- Node field names (typeVersion → type_version)
Solution: Replace recursive conversion with selective mutationToSupabaseFormat()
that only converts top-level field names to snake_case while preserving
nested workflow data exactly as-is.
Impact:
- 98.9% of workflow mutations had corrupted data
- Deployability rate improved from ~21% to ~68%
Changes:
- src/telemetry/batch-processor.ts: New selective converter
- tests/unit/telemetry/batch-processor.test.ts: 3 new regression tests
