Route 1,000+ tools through 1 MCP tool. The AI sees only the router — not all 1,000 tools. Table of Contents - Why QLN - What's New in v4.1 - Quick Start - How It Works - API Reference - MCP Auto-Discovery - Provider Manifests - Configuration - Project Structure - FAQ - Contributing Why QLN Every MCP tool eats context tokens. 10 tools? Fine. 100? Slow. 1,000? Impossible — context is full before the conversation starts. QLN solves this: 1. All tools are indexed in QLN's SQLite engine 2. The AI sees one tool : n2 qln call ( 200 tokens) 3. AI searches → finds the best match → executes with automatic fallback Result: 200 tokens instead of 50,000. 99.6% reduction. Features Feature Description --------- ------------- 1 tool = 1,000 tools AI sees n2 qln call ( 200 tokens), QLN routes to the right one Sub-5ms search 3-stage engine: trigger match → BM25 keyword → semantic vector Auto mode One-shot search + execute with confidence gating and fallback chain Circuit Breaker Auto-disable failing tools, self-recover after timeout MCP Auto-Discovery Scan external MCP servers and index their tools automatically Boost Keywords Curated terms with 2× BM25 weight for precision search Self-learning ranking Usage count + success rate feed back into scores Source weighting Prioritize tools by origin (mcp plugin local) Hot reload Edit providers/ manifests at runtime — auto re-indexed Bulk in","default_branch":null,"files":null,"tree":[],"storefront":"/r/choihyunsus","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/choihyunsus/n2-QLN/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
