# Install ATO (Agentic Tool Optimization)

**Canonical product URL:** https://agentictool.ai  
**Source:** https://github.com/WillNigri/Agentic-Tool-Optimization  
**License:** MIT

## macOS (Homebrew)

```bash
brew install willnigri/ato/ato
ato --version
ato demo-war-room
```

If the CLI is inside the desktop app bundle but not on PATH:

```bash
ato setup-path
# or bootstrap:
# /Applications/ATO.app/Contents/Resources/binaries/ato-<arch> setup-path
```

## Linux

```bash
curl -fsSL https://agentictool.ai/install.sh | sh
ato demo-war-room
```

## Windows

Download the installer from https://agentictool.ai/#download

## First 60 seconds

```bash
# Multi-LLM review on the current git diff (uses installed runtimes / keys you already have)
ato review --consensus

# Dispatch one prompt to a runtime
ato dispatch claude "Summarize the top risks in this repo's auth module"

# Local receipts live here (no cloud required)
sqlite3 ~/.ato/local.db "SELECT id, runtime, status, cost_usd_estimated FROM execution_logs ORDER BY created_at DESC LIMIT 5"
```

## Auth model

ATO is **bring your own keys / subscriptions**:

1. CLI subscriptions (`claude`, `codex`, `gemini`) when logged in
2. API keys you store locally
3. Optional cloud account for team workspaces / Pro automation

Core local ops do not require a cloud sign-in.

## Agent surfaces

| Surface | Best for |
|---|---|
| Desktop GUI | Humans creating agents, watching war-rooms |
| CLI `ato …` | Coding agents and scripts (JSON stdout) |
| MCP stdio | Harnesses that already speak MCP |
