Fossil MCP

Dead code detection for vibe-coded projects

4 followers

Visit website
AI coding tools write fast but never clean up. After a few sessions your project is full of dead functions, duplicated logic, and Phase 2 comments. Fossil scans your codebase and finds what's dead. Not grep — actual call graph analysis across 15 languages. It's also an MCP server. Connect it once and your AI agent can clean up after itself. Written in Rust. Single binary. Zero config. Open source.

Hey! I've been coding with Claude Code for 6+ months — at home, at work, basically all the time. I love it. But every project ends up the same way: Phase 2 comments everywhere, return True placeholders, and dead functions that nothing calls. After a few rounds of refactoring there's a bunch of code just sitting there disconnected. I tried asking Claude to clean it up. Terrible idea. Takes more tokens than writing the code in the first place. And the dead code is actually dangerous — the agent sees it while building something new, thinks "oh this looks useful", hooks into it, and now you've got bugs from code that was never meant to run. So I built Fossil. It builds an actual code graph and figures out what's reachable vs. dead. 15 languages, zero config, framework-aware so it won't flag your React lifecycle methods. The part I'm most excited about: it's an MCP server. You connect it once and Claude/Cursor can scan and clean up as part of a normal coding session. claude mcp add fossil fossil-mcp Ask me anything — would genuinely love feedback on where it breaks.
