GitWarren MCP server

GitWarren

gitwarren.com — the official site, with downloads for macOS, Windows and Linux. On macOS there is also a Homebrew cask:

brew install --cask klarluft/tap/gitwarren

There is a command line too, which serves the same review UI in a browser instead of an Electron window — for a machine that will not have the app on it, or one with no screen at all:

brew install klarluft/tap/gitwarren-cli               # macOS and Linux, brings its own Node
curl -fsSL https://gitwarren.com/install.sh | sh      # macOS and Linux, no Homebrew needed
npx gitwarren serve                                   # anywhere Node 22.14+ is, including Windows

Then gitwarren serve --open. See The gitwarren command line.

If you arrive from a coding agent, start there instead. The plugin brings the MCP server and a note that teaches the agent when to open a review and how to answer your comments:

/plugin marketplace add klarluft/gitwarren-app       # Claude Code, then:
/plugin install gitwarren@gitwarren
gemini extensions install https://github.com/klarluft/gitwarren-app
npx skills add klarluft/gitwarren-app                 # the note alone, for any agent

Cursor, Codex, VS Code and Kiro read the same repository from their plugin screens. See Installing it as a plugin.

Code review for your own git repositories, on your own machines. Your machines, your agents, no one else's server — and no account.

It runs as a desktop app on macOS, Windows and Linux, or as a command that serves the same review UI into a browser tab. Same renderer either way; the shell is the only thing that differs. A machine with no screen at all — a VPS, a WSL distro, a box an agent works on — runs the headless half and is reviewed from somewhere else.

Reviews live on the machine the code is on, and stay there. GitWarren reaches your other machines over SSH, over wsl.exe, or over your own tailnet, and nothing is replicated, relayed or stored anywhere but the computers you already own. See Your other machines.

Built for the moment a coding agent — Claude Code, Codex, or anything else that edits files on your disk — has just finished, and its work is sitting in your worktree uncommitted. Read that diff here, on your own machine, before it becomes a commit.

Tell GitWarren which local git repositories you care about, then open reviews against them — a review is a comparison of two refs, presented the way a pull request is, with conversation, commits and files changed tabs.

The part that makes it worth having: a review can include work that has not been committed. If the branch you are reviewing is checked out in a worktree, GitWarren finds that worktree — wherever it is — and folds its staged, unstaged and untracked changes into the diff. You can review a change before it is a commit, which is exactly when review is most useful.

Nothing is cached: every branch name, commit and diff on screen is read from git at the moment it is shown.

Local AI agents get the same capabilities through an MCP server over stdio, and a plugin puts it into Claude Code, Codex, Cursor, VS Code and Gemini CLI in one line — see Agent access (MCP).
