Hi HN! We built Context9 to reduce LLM hallucinations caused by outdated documentation. It’s an open-source tool built on Knowledge MCP. Why use it: - Real-time Sync: Feed the latest local docs/private repos to agents. No more stale context. - Reduce Halluclinations: Grounding agents in your current docs, not outdated training data. - Private-first: Everything stays local. No third-party indexing or data leaks. - No RAG Overhead: Skip complex vector DB setups. It’s agent-native and fast. - 100% Free: Open-source and local-first. Perfect for fast-evolving projects where static MCP servers can't keep up.
