* feat: add AI-powered documentation generation for community nodes Add system to fetch README content from npm and generate structured AI documentation summaries using local Qwen LLM. New features: - Database schema: npm_readme, ai_documentation_summary, ai_summary_generated_at columns - DocumentationGenerator: LLM integration with OpenAI-compatible API (Zod validation) - DocumentationBatchProcessor: Parallel processing with progress tracking - CLI script: generate-community-docs.ts with multiple modes - Migration script for existing databases npm scripts: - generate:docs - Full generation (README + AI summary) - generate:docs:readme-only - Only fetch READMEs - generate:docs:summary-only - Only generate AI summaries - generate:docs:incremental - Skip nodes with existing data - generate:docs:stats - Show documentation statistics - migrate:readme-columns - Apply database migration Conceived by Romuald Członkowski - www.aiadvisors.pl/en 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * feat: expose AI documentation summaries in MCP get_node response - Add AI documentation fields to NodeRow interface - Update SQL queries in getNodeDocumentation() to fetch AI fields - Add safeJsonParse helper method - Include aiDocumentationSummary and aiSummaryGeneratedAt in docs response - Fix parseNodeRow to include npmReadme and AI summary fields - Add truncateArrayFields to handle LLM responses exceeding schema limits - Bump version to 2.33.0 Conceived by Romuald Członkowski - www.aiadvisors.pl/en 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * test: add unit tests for AI documentation feature (100 tests) Added comprehensive test coverage for the AI documentation feature: - server-node-documentation.test.ts: 18 tests for MCP getNodeDocumentation() - AI documentation field handling - safeJsonParse error handling - Node type normalization - Response structure validation - node-repository-ai-documentation.test.ts: 16 tests for parseNodeRow() - AI documentation field parsing - Malformed JSON handling - Edge cases (null, empty, missing fields) - documentation-generator.test.ts: 66 tests (14 new for truncateArrayFields) - Array field truncation - Schema limit enforcement - Edge case handling All 100 tests pass with comprehensive coverage.

Increased threshold to 150ms to account for CI environment variability.

Database Layer Unit Tests
This directory contains comprehensive unit tests for the database layer components of n8n-mcp.
Test Coverage
node-repository.ts - 100% Coverage ✅
saveNodemethod with JSON serializationgetNodemethod with JSON deserializationgetAIToolsmethodsafeJsonParseprivate method- Edge cases: large JSON, boolean conversion, invalid JSON handling
template-repository.ts - 80.31% Coverage ✅
- FTS5 initialization and fallback
saveTemplatewith sanitizationgetTemplateandgetTemplatesByNodessearchTemplateswith FTS5 and LIKE fallbackgetTemplatesForTaskwith task mapping- Template statistics and maintenance operations
- Uncovered: Some error paths in FTS5 operations
database-adapter.ts - Tested via Mocks
- Interface compliance tests
- PreparedStatement implementation
- Transaction support
- FTS5 detection logic
- Error handling patterns
Test Strategy
The tests use a mock-based approach to:
- Isolate database operations from actual database dependencies
- Test business logic without requiring real SQLite/sql.js
- Ensure consistent test execution across environments
- Focus on behavior rather than implementation details
Key Test Files
node-repository-core.test.ts- Core NodeRepository functionalitytemplate-repository-core.test.ts- Core TemplateRepository functionalitydatabase-adapter-unit.test.ts- DatabaseAdapter interface and patterns
Running Tests
# Run all database tests
npm test -- tests/unit/database/
# Run with coverage
npm run test:coverage -- tests/unit/database/
# Run specific test file
npm test -- tests/unit/database/node-repository-core.test.ts
Mock Infrastructure
The tests use custom mock implementations:
MockDatabaseAdapter- Simulates database operationsMockPreparedStatement- Simulates SQL statement execution- Mock logger and template sanitizer for external dependencies
This approach ensures tests are fast, reliable, and maintainable.
