Mergify CLI

Drive Mergify from your terminal and CI pipelines: stacked pull requests, the merge queue, CI Insights, scheduled freezes, and configuration — all from a single self-contained binary that reuses your existing GitHub (gh) login.

mergify stack push          # turn your local commits into stacked PRs
mergify queue status        # inspect the merge queue
mergify ci junit-process report.xml   # upload test results to CI Insights

• One static binary. No runtime, no dependencies — drop it on a developer laptop or a CI runner and go.
• Zero-config auth. Picks up gh auth token automatically; override with env vars or flags when scripting.
• Built for pipelines. Logs to stderr, structured --json output on read commands, and stable exit codes for scripts and runbooks.
• Cross-platform. Linux, macOS (x86_64 + aarch64), and Windows.

Installation

Homebrew (recommended for macOS)

brew install mergifyio/tap/mergify-cli

The fully-qualified name taps and installs in one step. Upgrade with brew upgrade mergify-cli — not mergify self-update, which overwrites the Homebrew-managed binary. See the tap for tap-trust and short-name details.

Install script (recommended for Linux; also macOS — x86_64 and aarch64)

curl -fsSL https://raw.githubusercontent.com/Mergifyio/mergify-cli/main/install.sh | sh

Installs to ~/.local/bin/mergify. Override with MERGIFY_INSTALL_DIR=/usr/local/bin or pin a version with MERGIFY_VERSION=<version>. Upgrade with mergify self-update.

Manual download (Windows, or to bypass the script)

Grab the matching archive from the latest release:

• Windows — download mergify-<version>-x86_64-pc-windows-msvc.zip, extract it, and put mergify.exe anywhere on your PATH.
• Linux / macOS — download mergify-<version>-<target>.tar.gz (e.g. mergify-2026.4.23.1-aarch64-apple-darwin.tar.gz), extract with tar -xzf, and put the resulting mergify binary anywhere on your PATH.

Verify against SHA256SUMS from the same release if you care.

Authentication

Most commands talk to the Mergify and GitHub APIs and need a token. The CLI resolves credentials and target repository in this order, so an authenticated gh is usually all you need:

See the authentication guide for details.

Quick start

# Stacked pull requests — one PR per commit, kept in sync
mergify stack setup                # once per repo: install the git hooks the stack needs
mergify stack push                 # push commits and create/update their PRs
mergify stack list                 # show the stack and its PR status
mergify stack sync                 # rebase the stack onto its trunk

# Merge queue
mergify queue status               # current queue state for the repo
mergify queue status --json        # same, as machine-readable JSON

# CI Insights — from inside your pipeline
mergify ci junit-process report.xml --test-language python

# Configuration
mergify config validate            # check .mergify.yml against the schema

Run mergify --help for the full command list and mergify <command> --help for any command's flags.

Commands

Every command group maps to a section of the CLI reference.

• mergify stack — Create and maintain stacked pull requests. Docs
• mergify queue — Inspect and control the merge queue. Docs
• mergify events — Browse the events Mergify recorded for the repository or one pull request, as a timeline or JSON.
• mergify ci — Send JUnit results and pull request scopes from any CI provider. Docs
• mergify tests — Look up test health and manage the flaky-test quarantine. Docs
• mergify freeze — Schedule merge freezes for release windows and maintenance. Docs
• mergify config — Validate your configuration and simulate actions before you merge. Docs
• mergify self-update — Update the CLI to the latest release.
• mergify completions <shell> — Print a shell completion script (see below).

Run mergify <command> --help for a group's subcommands and flags.

Shell completions

Generate a completion script for your shell — bash, zsh, fish, elvish, or powershell:

# zsh — write to a directory on your $fpath
mergify completions zsh > ~/.zfunc/_mergify

# bash — load in your current session (add to ~/.bashrc to persist)
source <(mergify completions bash)

# fish
mergify completions fish > ~/.config/fish/completions/mergify.fish
