Zero-dependency C++23 CLI and MCP server that gives coding agents a ranked call graph to cut token use.

1.8kApache-2.0

The ripgrep of AI context: a zero-dependency C++23 CLI + MCP server for coding agents. Find what you want without reading the repo, then check you built what you meant — blast radius, tests-to-run, quality deltas. Signatures at 74.7% fewer bytes than bodies; every guess labelled, every loss published. Paddle out with a map.

Pros

  • +Zero runtime dependencies, single offline binary with no API key, embeddings, index server, or daemon
  • +Fast indexing (0.25-0.45s, 6.6-16.5MB) and warm queries (197ms) versus graph-database MCP servers
  • +Token-efficient signatures at 74.7% fewer bytes than full bodies, with labelled uncertainty and token budgets
  • +Auto-installs and activates task-shaped skills for Claude Code, Codex, Cursor, Windsurf, Gemini, opencode, and aider

Cons

  • −C++23 toolchain required to build from source
  • −Very new project with a fast-moving feature set and limited long-term track record
  • −Output is deliberately conservative, labelling floors and truncations rather than giving definitive totals

Target audience: Developers and teams running coding agents who want fast, token-efficient repository context without a server or API key.
