LaunchDarkly CLI: LaunchDarkly from the command line

LaunchDarkly in the terminal

LaunchDarkly controls which users see which features. Connected to a workspace, GBrain can answer “which flags are still on for everyone?”, turn a feature on for a customer, or clean up stale flags.

Create and update feature flags
Change targeting rules
Manage AI configs
Check a rollout's metrics

Install the CLI, then connect LaunchDarkly

LaunchDarkly is connected on its own sign-in page, in the browser. A key or a sign-in never passes through the terminal.

# Install the CLI
$ curl -sSL https://gbrainio.terminalwire.sh | bash

# Set the terminal up and connect it
$ gbrainio terminal connect

# What LaunchDarkly is, and each of its commands once it is connected
$ gbrainio tool help launchdarkly

The installer is a shell script for macOS and Linux. Read it before you run it.

LaunchDarkly's commands come from LaunchDarkly's own server once it is connected, so none are listed here.

Same tools, any AI

Claude Code, Cursor and Codex reach the same LaunchDarkly through MCP, on the same permission and the same record.
