Code Review Graph
tirth8205
Code Review Graph is a local-first code intelligence graph for MCP and CLI that cuts AI coding tool context by mapping only what matters.
Key features
- Persistent Repo Graph: Builds and maintains a graph of the codebase's symbols, references, and structure so lookups are instant on subsequent runs.
- MCP Server Integration: Exposes the graph as an MCP server so Claude Code, Cursor, and other MCP-compatible agents can query it directly.
- CLI Access: A first-class command-line interface lets developers query the graph without an agent in the loop.
- Task-Scoped Context Slices: Instead of loading whole files, returns only the pieces of code an AI tool needs — with benchmarked context reductions.
- Local-First Privacy: All indexing and serving runs on the developer's machine, so source code never leaves the environment.
- PyPI Distribution: Installs with a single `pip install code-review-graph` and works on any Python 3.10+ setup.
Best for
- Cheaper AI Code Reviews: Feed only the relevant slices of a change to a review agent so token spend on large PRs stays low.
- Large Monorepo Workflows: Give coding agents targeted context in repos too big to fit into any model's window.
- MCP-Compatible Agent Enhancement: Plug into Claude Code or Cursor as an MCP server to add repo-aware retrieval.
- Local Refactor Planning: Use the CLI to explore dependencies and impact before making cross-cutting changes.
- Air-Gapped Codebases: Keep proprietary source local while still using AI tools that consume the graph rather than raw files.
- Onboarding Assistance: Help new engineers navigate a large codebase by querying the graph for related symbols and callers.
Kalender Sync
