Ucn

UCN is a developer tool for static code analysis and navigation across various programming languages. It leverages tree-sitter for fast, source-linked answers to questions about code caller relationships, impact analysis, and test coverage—with explicit uncertainty labeling. UCN can be used as a CLI, as an add-on skill for AI agents, or integrated via MCP, making it valuable for developers, code reviewers, and AI agent builders seeking efficient, accurate, and incrementally indexed codebase understanding without project compilation.
