What is CRG?
CRG (Better Code Review Graph) builds a knowledge graph of your codebase with semantic search and call-graph resolution, so AI code reviews use fewer tokens and understand how changes ripple through the code. It runs as an MCP server.
Pros
- Cuts tokens used in AI code reviews
- Resolves call graphs across the codebase
- Apache-2.0 licensed
Cons
- Indexing takes time on large repos
- Young project
Who should use CRG
Developers who use AI for code review on larger codebases.
Who may not need it
People with very small projects.
