c76ffd9fb1 fix: sticky notes validation - eliminate false positives in workflow updates (#350)
Fixed critical bug where sticky notes (UI-only annotation nodes) incorrectly
triggered "disconnected node" validation errors when updating workflows via
MCP tools (n8n_update_partial_workflow, n8n_update_full_workflow).

Problem:
- Workflows with sticky notes failed validation with "Node is disconnected" errors
- n8n-validation.ts lacked sticky note exclusion logic
- workflow-validator.ts had correct logic but as private method
- Code duplication led to divergent behavior

Solution:
1. Created shared utility module (src/utils/node-classification.ts)
   - isStickyNote(): Identifies all sticky note type variations
   - isTriggerNode(): Identifies trigger nodes
   - isNonExecutableNode(): Identifies UI-only nodes
   - requiresIncomingConnection(): Determines connection requirements

2. Updated n8n-validation.ts to use shared utilities
   - Fixed disconnected nodes check to skip non-executable nodes
   - Added validation for workflows with only sticky notes
   - Fixed multi-node connection check to exclude sticky notes

3. Updated workflow-validator.ts to use shared utilities
   - Removed private isStickyNote() method (8 locations)
   - Eliminated code duplication

Testing:
- Created comprehensive test suites (54 new tests, 100% coverage)
- Tested with n8n-mcp-tester agent using real n8n instance
- All test scenarios passed including regression tests
- Validated against real workflows with sticky notes

Impact:
- Sticky notes no longer block workflow updates
- Matches n8n UI behavior exactly
- Zero regressions in existing validation
- All MCP workflow tools now work correctly with annotated workflows

Files Changed:
- NEW: src/utils/node-classification.ts
- NEW: tests/unit/utils/node-classification.test.ts (44 tests)
- NEW: tests/unit/services/n8n-validation-sticky-notes.test.ts (10 tests)
- MODIFIED: src/services/n8n-validation.ts (lines 198-259)
- MODIFIED: src/services/workflow-validator.ts (8 locations)
- MODIFIED: tests/unit/validation-fixes.test.ts
- MODIFIED: CHANGELOG.md (v2.20.8 entry)
- MODIFIED: package.json (version bump to 2.20.8)

Test Results:
- Unit tests: 54 new tests passing, 100% coverage on utilities
- Integration tests: All 10 sticky notes validation tests passing
- Regression tests: Zero failures in existing test suite
- Real-world testing: 4 test workflows validated successfully

* fix: align FTS5 tests with production boosting logic

Tests were failing because they used raw FTS5 ranking instead of the
exact-match boosting logic that production uses. Updated both test files
to replicate production search behavior from src/mcp/server.ts.

- Updated node-fts5-search.test.ts to use production boosting
- Updated database-population.test.ts to use production boosting
- Both tests now use JOIN + CASE statement for exact-match prioritization

This makes tests more accurate and less brittle to FTS5 ranking changes.

* fix: prioritize exact matches in FTS5 search with case-insensitive comparison

Root cause: SQL ORDER BY was sorting by FTS5 rank first, then CASE statement.
Since ranks are unique, the CASE boosting never applied. Additionally, the
CASE statement used case-sensitive comparison which failed to match nodes
like "Webhook" when searching for "webhook".

Changes:
- Changed ORDER BY from "rank, CASE" to "CASE, rank" in production code
- Added LOWER() for case-insensitive exact match detection
- Updated both test files to match the corrected SQL logic
- Exact matches now consistently rank first regardless of FTS5 score

Impact:
- Improves search quality by ensuring exact matches appear first
- More efficient SQL (less JavaScript sorting needed)
- Tests now accurately validate production search behavior
- Fixes 2/705 failing integration tests

Verified:
- Both tests pass locally after fix
- SQL query tested with SQLite CLI showing webhook ranks 1st

* docs: update CHANGELOG with FTS5 search fix details

Added comprehensive documentation for the FTS5 search ranking bug fix:
- Problem description with SQL examples showing wrong ORDER BY
- Root cause analysis explaining why CASE statement never applied
- Case-sensitivity issue details
- Complete fix description for production code and tests
- Impact section covering search quality, performance, and testing
- Verified search results showing exact matches ranking first

This documents the critical bug fix that ensures exact matches
appear first in search results (webhook, http, code, etc.) with
case-insensitive matching.

### 🐛 Bug Fixes
**Sticky Notes Validation - Disconnected Node False Positives**
Fixed critical bug where sticky notes (UI-only annotation nodes) were incorrectly triggering "disconnected node" validation errors when updating workflows via MCP tools.
#### Problem
- Workflows with sticky notes failed validation with "Node is disconnected" errors
- `n8n_update_partial_workflow` and `n8n_update_full_workflow` tools blocked legitimate updates
- Example error: "Validation Error: Node '📝 Webhook Trigger' is disconnected"
- Sticky notes are UI-only annotations and should never trigger connection validation
#### Root Cause Analysis
**Inconsistent Validation Logic:**
- `src/services/workflow-validator.ts` correctly excluded sticky notes using private `isStickyNote()` method
- `src/services/n8n-validation.ts` lacked sticky note exclusion logic entirely
- Code duplication led to divergent behavior between validators
**Missing Checks in n8n-validation.ts:**
```typescript
// BEFORE (Broken) - lines 246-257:
const webhookTypes = new Set([
'n8n-nodes-base.webhook',
'n8n-nodes-base.webhookTrigger',
'n8n-nodes-base.manualTrigger'
]);
// Only checked for webhooks, missed sticky notes entirely
const disconnectedNodes = workflow.nodes.filter(node => {
const isConnected = connectedNodes.has(node.name);
const isTrigger = webhookTypes.has(node.type);
// ...
});
```
#### Fixed
**1. Created Shared Utility Module** (`src/utils/node-classification.ts`)
- Centralized node classification logic to ensure consistency
- Four core functions:
- `isStickyNote()`: Identifies all sticky note type variations
- `isTriggerNode()`: Identifies trigger nodes (webhook, manual, cron, schedule)
- `isNonExecutableNode()`: Identifies UI-only nodes
- `requiresIncomingConnection()`: Determines if node needs incoming connections
**2. Updated n8n-validation.ts** (lines 198-259)
- Added imports: `import { isNonExecutableNode, isTriggerNode } from '../utils/node-classification'`
- Fixed disconnected nodes check to skip non-executable nodes:
```typescript
// AFTER (Fixed):
const disconnectedNodes = workflow.nodes.filter(node => {
// Skip non-executable nodes (sticky notes, etc.) - they're UI-only annotations
if (isNonExecutableNode(node.type)) {
return false;
}
const isConnected = connectedNodes.has(node.name);
const isTrigger = isTriggerNode(node.type);
// ...
});
```
- Added validation for workflows with only sticky notes
- Fixed multi-node connection check to exclude sticky notes when counting executable nodes
**3. Updated workflow-validator.ts** (8 locations)
- Removed private `isStickyNote()` method
- Replaced all calls with `isNonExecutableNode()` from shared utilities
- Eliminates code duplication
#### Testing
**New Test Files:**
- `tests/unit/utils/node-classification.test.ts`: 44 tests, 100% coverage
- Tests all classification functions
- Tests all sticky note type variations
- Tests trigger node identification
- Integration scenarios
- `tests/unit/services/n8n-validation-sticky-notes.test.ts`: 10 comprehensive tests
- Workflows with sticky notes and connected functional nodes
- Multiple sticky notes (10+ notes)
- All sticky note type variations
- Complex real-world scenarios (simulates POST /auth/login workflow)
- Detection of truly disconnected functional nodes
- Regression tests matching n8n UI behavior
**Updated Test Files:**
- `tests/unit/validation-fixes.test.ts`: Updated terminology to reflect shared utilities
**Test Results:**
- All 54 new tests passing
- 100% coverage on node-classification utilities
- Zero regressions in existing test suite
#### Impact
**Workflow Updates:**
- ✅ Sticky notes no longer block workflow updates
-`n8n_update_partial_workflow` works correctly with annotated workflows
-`n8n_update_full_workflow` accepts workflows with documentation notes
- ✅ Matches n8n UI behavior exactly
**Code Quality:**
- ✅ Eliminated code duplication between validators
- ✅ Centralized node classification logic
- ✅ Future node types can be added in one place
- ✅ Consistent behavior across all validation paths
**Node Type Support:**
- ✅ Handles all sticky note variations: `n8n-nodes-base.stickyNote`, `nodes-base.stickyNote`, `@n8n/n8n-nodes-base.stickyNote`
- ✅ Proper trigger node detection: webhook, webhookTrigger, manualTrigger, cronTrigger, scheduleTrigger
- ✅ Correct connection requirements for all node types
**Backward Compatibility:**
- ✅ No breaking changes
- ✅ All existing validations continue to work
- ✅ API remains unchanged

## [2.20.7] - 2025-10-22
### 🔄 Dependencies
**Updated n8n to v1.116.2**
Updated all n8n dependencies to the latest compatible versions:
- `n8n`: 1.115.2 → 1.116.2
- `n8n-core`: 1.114.0 → 1.115.1
- `n8n-workflow`: 1.112.0 → 1.113.0
- `@n8n/n8n-nodes-langchain`: 1.114.1 → 1.115.1
**Database Rebuild:**
- Rebuilt node database with 542 nodes from updated n8n packages
- All 542 nodes loaded successfully from both n8n-nodes-base (439 nodes) and @n8n/n8n-nodes-langchain (103 nodes)
- Documentation mapping completed for all nodes
**Testing:**
- Changes validated in CI/CD pipeline with full test suite (705 tests)
- Critical nodes validated: httpRequest, code, slack, agent
### 🐛 Bug Fixes
**FTS5 Search Ranking - Exact Match Prioritization**
Fixed critical bug in production search where exact matches weren't appearing first in search results.
#### Problem
- SQL ORDER BY clause was `ORDER BY rank, CASE ... END` (wrong order)
- FTS5 rank sorted first, CASE statement only acted as tiebreaker
- Since FTS5 ranks are always unique, CASE boosting never applied
- Additionally, CASE used case-sensitive comparison failing to match nodes like "Webhook" when searching "webhook"
- Result: Searching "webhook" returned "Webflow Trigger" first, actual "Webhook" node ranked 4th
#### Root Cause Analysis
**SQL Ordering Issue:**
```sql
-- BEFORE (Broken):
ORDER BY rank, CASE ... END -- rank first, CASE never used
-- Result: webhook ranks 4th (-9.64 rank)
-- Top 3: webflowTrigger (-10.20), vonage (-10.09), renameKeys (-10.01)
-- AFTER (Fixed):
ORDER BY CASE ... END, rank -- CASE first, exact matches prioritized
-- Result: webhook ranks 1st (CASE priority 0)
```
**Case-Sensitivity Issue:**
- Old: `WHEN n.display_name = ?` (case-sensitive, fails on "Webhook" vs "webhook")
- New: `WHEN LOWER(n.display_name) = LOWER(?)` (case-insensitive, matches correctly)
#### Fixed
**1. Production Code** (`src/mcp/server.ts` lines 1278-1295)
- Changed ORDER BY from: `rank, CASE ... END`
- To: `CASE WHEN LOWER(n.display_name) = LOWER(?) ... END, rank`
- Added case-insensitive comparison with LOWER() function
- Exact matches now consistently appear first in search results
**2. Test Files Updated**
- `tests/integration/database/node-fts5-search.test.ts` (lines 137-160)
- `tests/integration/ci/database-population.test.ts` (lines 206-234)
- Both updated to match corrected SQL logic with case-insensitive comparison
- Tests now accurately validate production search behavior
#### Impact
**Search Quality:**
- ✅ Exact matches now always rank first (webhook, http, code, etc.)
- ✅ Case-insensitive matching works correctly (Webhook = webhook = WEBHOOK)
- ✅ Better user experience - predictable search results
- ✅ SQL query more efficient (correct ordering at database level)
**Performance:**
- Same or better performance (less JavaScript sorting needed)
- Database does the heavy lifting with correct ORDER BY
- JavaScript sorting still provides additional relevance refinement
**Testing:**
- All 705 tests passing (703 passed + 2 fixed)
- Comprehensive testing by n8n-mcp-tester agent
- Code review approved with minor optimization suggestions for future
**Verified Search Results:**
- "webhook" → nodes-base.webhook (1st)
- "http" → nodes-base.httpRequest (1st)
- "code" → nodes-base.code (1st)
- "slack" → nodes-base.slack (1st)
- All case variations work correctly (WEBHOOK, Webhook, webhook)
## [2.20.6] - 2025-10-21
### 🐛 Bug Fixes
**Issue #342: Missing `tslib` Dependency Causing MODULE_NOT_FOUND on Windows**
Fixed critical dependency issue where `tslib` was missing from the published npm package, causing immediate failure when users ran `npx n8n-mcp@latest` on Windows (and potentially other platforms).
#### Problem
Users installing via `npx n8n-mcp@latest` experienced MODULE_NOT_FOUND errors:
```
Error: Cannot find module 'tslib'
Require stack:
- node_modules/@supabase/functions-js/dist/main/FunctionsClient.js
- node_modules/@supabase/supabase-js/dist/main/index.js
- node_modules/n8n-mcp/dist/telemetry/telemetry-manager.js
```
**Root Cause Analysis:**
- `@supabase/supabase-js` depends on `@supabase/functions-js` which requires `tslib` at runtime
- `tslib` was NOT explicitly listed in `package.runtime.json` dependencies
- The publish script (`scripts/publish-npm.sh`) copies `package.runtime.json``package.json` before publishing to npm
- CI/CD workflow (`.github/workflows/release.yml` line 329) does the same: `cp package.runtime.json $PUBLISH_DIR/package.json`
- Result: Published npm package had no `tslib` dependency
- When users installed via `npx`, npm didn't install `tslib` → MODULE_NOT_FOUND error
**Why It Worked Locally:**
- Local development uses main `package.json` which has full n8n package dependencies
- `tslib` existed as a transitive dependency through AWS SDK packages
- npm's hoisting made it available locally
**Why It Failed in Production:**
- `npx` installations use the published package (which comes from `package.runtime.json`)
- No transitive path to `tslib` in the minimal runtime dependencies
- npm's dependency resolution on Windows didn't hoist it properly
**Why Docker Worked:**
- Docker builds used `package-lock.json` which included all transitive dependencies
- Or the base image already had `tslib` installed
#### Fixed
**1. Added `tslib` to Runtime Dependencies**
- Added `"tslib": "^2.6.2"` to `package.runtime.json` dependencies (line 14)
- This is the **critical fix** since `package.runtime.json` gets published to npm
- Version `^2.6.2` matches existing transitive dependency versions
**2. Added `tslib` to Development Dependencies**
- Added `"tslib": "^2.6.2"` to `package.json` dependencies (line 154)
- Ensures consistency between development and production
- Prevents confusion for developers
**3. Synced `package.runtime.json` Version**
- Updated `package.runtime.json` version from `2.20.2` to `2.20.5`
- Keeps runtime package version in sync with main package version
#### Technical Details
**Dependency Chain:**
```
n8n-mcp
└── @supabase/supabase-js@2.57.4
└── @supabase/functions-js@2.4.6
└── tslib (MISSING) ❌
```
**Publish Process:**
```bash
# CI/CD workflow (.github/workflows/release.yml:329)
cp package.runtime.json $PUBLISH_DIR/package.json
npm publish --access public
# Users install via npx
npx n8n-mcp@latest
# → Gets dependencies from package.runtime.json (now includes tslib ✅)
```
**Files Modified:**
- `package.json` line 154: Added `tslib: "^2.6.2"`
- `package.runtime.json` line 14: Added `tslib: "^2.6.2"` (critical fix)
- `package.runtime.json` line 3: Updated version `2.20.2``2.20.5`
#### Impact
**Before Fix:**
- ❌ Package completely broken on Windows for `npx` users
- ❌ Affected all platforms using `npx` (not just Windows)
- ❌ 100% failure rate on fresh installations
- ❌ Workaround: Use v2.19.6 or install with `npm install` + run locally
**After Fix:**
-`npx n8n-mcp@latest` works on all platforms
-`tslib` guaranteed to be installed with the package
- ✅ No breaking changes (adding a dependency that was already in transitive tree)
- ✅ Consistent behavior across Windows, macOS, Linux
#### Verification
**Build & Tests:**
- ✅ TypeScript compilation passes
- ✅ Type checking passes (`npm run typecheck`)
- ✅ All tests pass
- ✅ Build succeeds (`npm run build`)
**CI/CD Validation:**
- ✅ Verified CI workflow copies `package.runtime.json``package.json` before publish
- ✅ Confirmed `tslib` will be included in published package
- ✅ No changes needed to CI/CD workflows
#### Related
- **Issue:** #342 - Missing `tslib` dependency in v2.20.3 causing MODULE_NOT_FOUND error on Windows
