- 📚 360 Documents - 291 developer guides + 69 release notes (Apex, LWC, REST API, Metadata API, and more)
- 🏠 100% Local - All data stays on your machine, works offline
- ⚡ Fast - Sub-second query latency with intelligent filtering + LRU caching
- 🔍 Smart Fallback - Expands search if topic-filtered results are sparse
- 📦 Packageable - Pure JavaScript (sql.js), no native dependencies
- 🔐 Secure - Parameterized queries, input validation with zod

🎯 Intent-Based Search
The MCP server automatically detects the topic of your query and searches in the most relevant documentation:
| Query | Detected Intent | Searches In |
|---|---|---|
| "How to create an Apex trigger" | Apex Development | ~15 Apex docs |
| "REST API OAuth authentication" | REST API | ~10 REST API docs |
| "LWC wire decorator" | Lightning/LWC | ~12 Lightning docs |
| "Bulk API 2.0 job" | Bulk API | ~5 Bulk API docs |
| "sharing rules permission set" | Security | 12 Security docs |
| "SOQL query limits" | SOQL/SOSL | ~5 SOQL docs |
Benefits:
- 🎯 More relevant results - Searches in topic-specific docs first
- ⚡ Faster queries - Scans ~15 docs instead of 357
- 🔄 Smart fallback - Expands search if too few results found
Override: You can always specify category or subcategory to search in a specific area.

⚡ Performance
| Metric | Value |
|---|---|
| PDF Documents | 360 (291 + 69 release notes) |
| Documents indexed | 357 |
| Search chunks | ~156,000 |
| Database size | ~520 MB |
| Intent-filtered query | < 50ms (scoped search) |
| Unfiltered query | < 500ms (full corpus) |
| Cached query | < 10ms |
How Intent-Based Search Improves Performance
Traditional Search:
"Apex trigger" → Scan all 156K chunks → Filter → Rank → ~500ms
Intent-Based Search:
"Apex trigger" → Detect: Apex (high confidence)
→ Filter to apex subcategory (~15 docs, ~6,000 chunks)
→ Scan → Rank → ~50ms
Note: Uses sql.js (pure JavaScript SQLite) with LIKE-based text search. Intent detection reduces search scope by 90%+ for topic-specific queries.
🔐 Security
- 100% Local: No data leaves your machine
- No API Keys: Works completely offline
- stdio Transport: No exposed HTTP endpoints
- Parameterized Queries: Protection against SQL injection
- Input Validation: All tool inputs validated with zod schemas
