Indexed code navigation for AI coding agents (Claude Code, Cursor, any MCP client) — replaces grep scans with GNU Global (gtags) lookups. ~100x faster, radically less context noise. One-line no-sudo install, everything in user space.
Setup
Choose your client, copy the config, then fill in any required environment variables.
