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 We built Context9 to reduce LLM hallucinations caused by outdated documentation.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- Reduce Halluclinations: Grounding agents in your current docs, not outdated training data.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.
