Review the live worktree
GitWarren reads the active worktree directly, including staged, unstaged, and untracked files, so you can inspect the full set of changes before a commit exists.
GitWarren
GitWarren is a desktop app for local Git code review, combining staged, unstaged, and untracked changes before a commit or pull request, with an MCP server for local AI agents.
Overview
GitWarren is a desktop app for reviewing Git worktrees locally before anything is committed or pushed. It is aimed at the gap between an agent finishing a task and the point where its changes become a pull request, so you can inspect the diff on your own machine first.
The app reads staged, unstaged, and untracked files directly from the worktree and combines them into a single review view. It also ships an MCP server over stdio so local AI agents can take part in the review by reading discussions, replying in threads, and leaving or resolving comments.
Features
Review before pull requests
The app folds the worktree into one diff and lets you read and comment on files that have not yet been committed or pushed.
MCP-based agent interaction
An MCP server over stdio exposes the same review tools to local agents such as Claude Code and Codex, letting them participate in the discussion.
Threaded review actions for agents
Agents can open a review, read the thread history, reply in a thread, leave line comments, and resolve comments using the same review surface.
Clear attribution
Each machine-written comment is marked as machine-written, and the tool name comes from the MCP handshake rather than the model itself.
Local storage with live Git reads
Reviews and comments are stored locally in one SQLite file in the application-data directory, while branch names, commits, and diffs are read from git when shown.
Use cases
Review agent output before commit
Use GitWarren when an agent finishes a task and leaves a dirty worktree. You can inspect the changes immediately, before committing or turning them into a pull request.
Inspect the full worktree
Use it for local code review on your own machine when you want to see staged, unstaged, and untracked files together in one diff rather than reviewing only committed work.
Let agents answer in the review thread
Use the MCP server when you want an AI agent to respond to review feedback directly inside the discussion, rather than in a separate chat or external tool.
Keep reviews local
Use GitWarren when you want review history, comments, and repository context to remain local instead of being stored in a hosted service or shared account.
