codesynapse indexes your codebase into a real code graph — callers, callees, class hierarchies, trait implementations — then exposes it as 32 MCP tools.
Instead of grepping files, your AI traces actual call chains. Hybrid BM25 + dense embeddings (local, no API key) finds the right code even when the function name has nothing to do with the query.
Works with Claude Code, Cursor, Windsurf, Kiro. Rust binary, ~10MB. Fully local — no data leaves your machine.
