Hey Product Hunt! I built CodeSpine after getting frustrated with AI coding assistants hallucinating method signatures and missing cross-module dependencies in my Java monorepo. The core insight: AI agents don't need to read your entire codebase — they need a structured index they can query on demand. CodeSpine indexes your project once and exposes it via MCP (Model Context Protocol), so instead of feeding 30 files into context per query, the agent makes one call and gets exactly what it needs: caller trees, impact paths, dead code reports, and execution flows. Results on my own projects: ~90% fewer tokens per query and zero hallucinated method signatures. MIT licensed and works with any MCP-compatible AI agent (Claude, Cursor, etc.). Would love feedback from anyone working with large Java codebases! GitHub: https://github.com/vinayak3022/c... LinkedIn: https://www.linkedin.com/in/thev...
