Vesalius: an on-device code graph for Claude Code

Hi everyone. I built Vesalius, an on-device code graph for Claude Code, in Swift. It maps your codebase (symbols, calls, files) and serves that map to Claude Code through an MCP server, CLI, Mac app, or VS Code extension, so the agent can answer questions about your code in one query instead of a chain of searches. Indexing is 100% local and your code never uploads. In a benchmark over 20 real questions, Claude Code alone used 204k tokens per question at 97.8 quality, versus 113k tokens at 97....
