# Gemini CLI in microManager

microManager runs Google’s Gemini CLI over the Agent Client Protocol by starting gemini --acp, so Gemini sessions run in parallel with your other agents, each in its own git worktree.

Updated 8 November 2026

## How does microManager run Gemini CLI?

The built-in Gemini CLI profile runs:

```sh
gemini --acp
```

in the workspace’s worktree and talks to it over the Agent Client Protocol. It uses the `gemini` on your login shell’s `PATH`, or the absolute path you set in Settings → Agents. The profile’s arguments are editable, so you can follow changes to Gemini CLI’s flags without waiting for a microManager update.

## Who can still use Gemini CLI?

Google’s [Gemini CLI README](https://github.com/google-gemini/gemini-cli) says that since 18 June 2026 it is for organizations with Gemini Code Assist Standard or Enterprise, or Code Assist for GitHub, on Google Cloud, plus older paid Gemini API and Vertex AI keys. Free Google accounts and Google AI Pro and Ultra moved to [Antigravity CLI](https://antigravity.google/docs/cli/acp) (`agy`).

Antigravity CLI speaks the Agent Client Protocol too. To use it, sign in once by running `agy` in a terminal, then in Settings → Agents choose **Add ACP agent** with the command `agy` and the argument `acp`.

## What works with Gemini CLI?

Streamed replies, tool calls as cards, plans, permission requests, model choice when Gemini offers it and slash commands, plus microManager’s [MCP tools](https://micromanager.win/docs/mcp-tools). Worktrees, checkpoints, diff review and pull requests work as they do for every agent.

## What do I need?

Gemini CLI installed and signed in with an account it still serves, so that `gemini` works in your terminal.

## Frequently asked questions

### Can I use Gemini CLI with a free Google account or Google AI Pro?

Not any more. Since 18 June 2026, Gemini CLI is for Gemini Code Assist Standard and Enterprise, Code Assist for GitHub on Google Cloud, and paid Gemini API or Vertex AI keys. Free accounts and Google AI Pro and Ultra moved to Antigravity CLI, which you can add to microManager as an ACP agent with the command agy and the argument acp.

### Does Gemini CLI need anything special?

Only to be installed and signed in with an account that can still use it. microManager starts it with its ACP flag; if your version uses a different flag, change the arguments in Settings → Agents.

### Can Gemini review another agent's work?

Yes. Open a Gemini tab in the same workspace and ask it to review; it can read the diff and leave line comments through microManager's MCP tools.
