## [Unreleased]
|
||||
|
||||
## [2.46.1] - 2026-04-03
|
||||
|
||||
### Fixed
|
||||
|
||||
- **Fix SSE reconnection loop** — SSE clients entering rapid reconnection loops because `POST /mcp` never routed messages to `SSEServerTransport.handlePostMessage()` (Fixes #617). Root cause: SSE sessions were stored in a separate `this.session` property invisible to the StreamableHTTP POST handler
|
||||
- **Add authentication to SSE endpoints** — `GET /sse` and `POST /messages` now require Bearer token authentication, closing an auth gap where SSE connections were unauthenticated
|
||||
- **Fix rate limiter exhaustion during reconnection** — added `skipSuccessfulRequests: true` to `authLimiter` so legitimate requests don't count toward the rate limit, preventing 429 storms during SSE reconnection loops
|
||||
|
||||
### Changed
|
||||
|
||||
- **Separate SSE endpoints (SDK pattern)** — SSE transport now uses dedicated `GET /sse` + `POST /messages` endpoints instead of sharing `/mcp` with StreamableHTTP, following the official MCP SDK backward-compatible server pattern
|
||||
- **Unified auth into `authenticateRequest()` method** — consolidated duplicated Bearer token validation logic from three endpoints into a single method with consistent JSON-RPC error responses
|
||||
- **SSE sessions use shared transports map** — removed the legacy `this.session` singleton; SSE sessions are now stored in the same `this.transports` map as StreamableHTTP sessions with `instanceof` guards for type discrimination
|
||||
|
||||
### Deprecated
|
||||
|
||||
- **SSE transport (`GET /sse`, `POST /messages`)** — SSE is deprecated in MCP SDK v1.x and removed in v2.x. Clients should migrate to StreamableHTTP (`POST /mcp`). These endpoints will be removed in a future major release
|
||||
|
||||
### Security
|
||||
|
||||
- **Rate limiting on all authenticated endpoints** — `authLimiter` now applied to `GET /sse` and `POST /messages` in addition to `POST /mcp`
|
||||
- **Transport type guards** — `instanceof` checks prevent cross-protocol access (SSE session IDs rejected on StreamableHTTP endpoint and vice versa)

## [2.46.0] - 2026-04-03
|
||||
|
||||
### Added
|
||||
|
||||
- **`patchNodeField` operation for `n8n_update_partial_workflow`** — a dedicated, strict find/replace operation for surgical string edits in node fields (Fixes #696). Key features:
|
||||
- **Strict error handling**: errors if find string not found (unlike `__patch_find_replace` which only warns)
|
||||
- **Ambiguity detection**: errors if find matches multiple times unless `replaceAll: true` is set
|
||||
- **`replaceAll` flag**: replace all occurrences of a string in a single patch
|
||||
- **`regex` flag**: use regex patterns for advanced find/replace
|
||||
- Top-level operation type for better discoverability
|
||||
|
||||
### Security
|
||||
|
||||
- **Prototype pollution protection** — `setNestedProperty` and `getNestedProperty` now reject paths containing `__proto__`, `constructor`, or `prototype`. Protects both `patchNodeField` and `updateNode` operations
|
||||
- **ReDoS protection** — regex patterns with nested quantifiers or overlapping alternations are rejected to prevent catastrophic backtracking
|
||||
- **Resource limits** — max 50 patches per operation, max 500-char regex patterns, max 512KB field size for regex operations

## [2.45.1] - 2026-04-02
|
||||
|
||||
### Fixed
|
||||
|
||||
- **Use stdio-wrapper.js as default bin entry point** — the previous entry point (`index.js`) wrote INFO-level logs to stdout, corrupting JSON-RPC MCP transport for stdio-mode users (Fixes #693, Related: #555, #628)
|
||||
- **Preserve node credentials during full workflow updates** — `n8n_update_full_workflow` now carries forward existing credential references from the server when user-provided nodes omit them, preventing "missing credentials" errors on PUT (Fixes #689)
|
||||
|
||||
### Changed
|
||||
|
||||
- **Updated publish scripts** to use `stdio-wrapper.js` as the npm bin entry point, ensuring the fix persists across releases

## [2.44.1] - 2026-04-01
|
||||
|
||||
### Security
|
||||
|
||||
- **Bump axios** from `^1.11.0` to `^1.14.0` to patch known vulnerability
|
||||
- **Bump nodemon** from `^3.1.10` to `^3.1.14` to patch transitive dependency vulnerabilities
|
||||
|
||||
### Changed
|
||||
|
||||
- **Upgrade GitHub Actions** to latest versions across all CI/CD workflows (docker, release, test, update-n8n-deps) — contributed by @salmanmkc in #663

## [2.44.0] - 2026-04-01
|
||||
|
||||
### Added
|
||||
|
||||
- **Multi-step workflow generation flow**: `n8n_generate_workflow` now supports a three-step flow where AI agents act as quality gates — get proposals, review, then deploy. New parameters: `deploy_id` (deploy a specific proposal), `confirm_deploy` (deploy a previously generated preview).
|
||||
|
||||
- **`GenerateWorkflowProposal` type**: New exported type for workflow proposals with `id`, `name`, `description`, `flow_summary`, and `credentials_needed` fields.
|
||||
|
||||
- **`status` field on `GenerateWorkflowResult`**: Indicates the current phase — `proposals`, `preview`, `deployed`, or `error`.
|
||||
|
||||
### Changed
|
||||
|
||||
- **Tool description updated**: `n8n_generate_workflow` description now explains the multi-step flow instead of auto-deploy behavior.
|
||||
|
||||
- **Tool documentation updated**: Essentials and full docs reflect the three-step flow with examples for each step.

||||

||||

|
||||
## [2.43.0] - 2026-03-31
|
||||
|
||||
### Added
|
||||
|
||||
- **`n8n_generate_workflow` tool**: New MCP tool that enables AI-powered workflow generation from natural language descriptions. Available on the hosted service with handler delegation pattern for extensibility.
|
||||
|
||||
- **Handler injection API**: `EngineOptions.generateWorkflowHandler` allows hosting environments to provide custom workflow generation backends. Handler receives helpers for `createWorkflow`, `validateWorkflow`, `autofixWorkflow`, and `getWorkflow`.
|
||||
|
||||
- **Tool documentation**: Full essentials and deep documentation for `n8n_generate_workflow` via `tools_documentation`.
|
||||
|
||||
### Fixed
|
||||
|
||||
- **Tools documentation count**: Corrected n8n API tools count and added missing `n8n_manage_datatable` entry to tools overview.

|
||||
## [2.42.3] - 2026-03-30
|
||||
|
||||
### Improved
|
||||
|
||||
- **Patterns response trimmed for token efficiency** (Issue #683): Task-specific patterns response reduced ~64% — dropped redundant `displayName`, shortened field names (`frequency` → `freq`), capped chains at 5, and shortened chain node types to last segment.
|
||||
|
||||
- **`patterns` mode added to `tools_documentation`**: Was missing from both essentials and full docs. AI agents can now discover patterns mode through the standard documentation flow.
|
||||
|
||||
- **`includeOperations` omission behavior documented**: Added note that trigger nodes and freeform nodes (Code, HTTP Request) omit the `operationsTree` field.
|
||||
|
||||
- **`search_nodes` examples trimmed**: Reduced from 11 to 6 examples in full docs, removing near-duplicates.

|
||||
## [2.42.2] - 2026-03-30
|
||||
|
||||
### Fixed
|
||||
|
||||
- **`workflow-patterns.json` missing from npm package** (Issue #681): Added `data/workflow-patterns.json` to the `files` array in `package.json` so the patterns file is included in the published npm package and works out of the box without manual generation.

|

## [2.42.1] - 2026-03-30
|
||||
|
||||
### Fixed
|
||||
|
||||
- **Community nodes missing from database after rebuild**: Restored 584 community nodes from the n8n 2.13.3 snapshot and re-extracted operations with resource grouping from `properties_schema`. 366 community nodes now have proper resource-grouped operations.
|
||||
|
||||
- **Community node service missing resource extraction**: `extractOperations()` in `community-node-service.ts` was not extracting `resource` from `displayOptions.show.resource`, same issue that was fixed in `property-extractor.ts` in v2.42.0.

||||

|
||||
## [2.42.0] - 2026-03-30
|
||||
|
||||
### Added
|
||||
|
||||
- **`includeOperations` flag for search_nodes**: Opt-in parameter that returns a resource/operation tree per search result, grouped by resource (e.g., Slack returns 7 resources with 44 operations). Saves a mandatory `get_node` round-trip when building workflows. Adds ~100-300 tokens per result.
|
||||
|
||||
- **`searchMode: "patterns"` for search_templates**: New lightweight mode that serves workflow pattern summaries mined from 2,700+ templates. Returns common node combinations, connection chains, and frequency data per task category (10 categories: ai_automation, webhook_processing, scheduling, etc.). Use `task` parameter for category-specific patterns or omit for overview.
|
||||
|
||||
- **Workflow pattern mining script** (`npm run mine:patterns`): Extracts node frequency, co-occurrence, and connection topology from the template database. Two-pass pipeline: Pass 1 analyzes `nodes_used` metadata (no decompression), Pass 2 decompresses workflows for connection analysis. Produces `data/workflow-patterns.json` with 554 node types, 3,201 edges, and 5,246 chains.
|
||||
|
||||
### Fixed
|
||||
|
||||
- **Operations extraction now includes resource grouping**: The property extractor was using `find()` to get only the first `operation` property, but n8n nodes have multiple operation properties each mapped to a different resource via `displayOptions.show.resource`. Changed to `filter()` to capture all operation properties. Slack went from 17 flat operations to 44 operations across 7 named resources.
|
||||
|
||||
- **FTS-to-LIKE fallback dropped search options**: When the FTS5 search fell back to LIKE-based search (e.g., for "http request"), the `options` object (including `includeOperations`, `includeExamples`, `source`) was silently lost. Now correctly passed through.

|

## [2.41.4] - 2026-03-30
|
||||
|
||||
### Fixed
|
||||
|
||||
- **`validate_workflow` misses `conditions.options` check for If/Switch nodes** (Issue #675): Added version-conditional validation — If v2.2+ and Switch v3.2+ now require `conditions.options` metadata, If v2.0-2.1 validates operator structures, and v1.x is left unchecked. Previously only caught by `n8n_create_workflow` pre-flight but not by offline `validate_workflow`.
|
||||
|
||||
- **False positive "Set node has no fields configured" for Set v3+** (Issue #676): The `validateSet` checker now recognizes `config.assignments.assignments` (v3+ schema) in addition to `config.values` (v1/v2 schema). Updated suggestion text to match current UI terminology.
|
||||
|
||||
- **Expression validator does not detect unwrapped n8n expressions** (Issue #677): Added heuristic pre-pass that detects bare `$json`, `$node`, `$input`, `$execution`, `$workflow`, `$prevNode`, `$env`, `$now`, `$today`, `$itemIndex`, and `$runIndex` references missing `={{ }}` wrappers. Uses anchored patterns to avoid false positives. Emits warnings, not errors.
