About cq27-dev/rag-rat

Rag-rat is a local repository intelligence tool that indexes codebases for semantic search, symbol navigation, and impact analysis. It operates as an MCP (Model Context Protocol) server and integrates with git and GitHub to provide a change history trail. The tool builds a source-anchored memory graph to support contextual code understanding.

Best for

Developers needing local semantic code search and impact analysis

Use cases

  • Semantically search across a local codebase
  • Navigate symbol dependencies and graph relationships
  • Preflight impact surfaces before making changes

Notes

8 stars on GitHub. Last updated 2026-07-13. Licensed MIT.

Pros

  • Rust implementation offers fast indexing and queries
  • Integrates with git and GitHub for change audit trail

Cons

  • Small community and limited documentation due to its early stage (8 stars)
  • Requires familiarity with the MCP protocol for integration
  • May have overhead for very large repositories
