# CrewTower > CrewTower is a native macOS app that turns the MacBook notch into a live control tower for local AI coding agents: it shows what every session is doing, lets you approve or deny permission requests without touching the terminal, and jumps to the exact terminal tab or pane that needs you. Name: CrewTower is one word; earlier listings wrote it as Crew Tower. CrewTower the Mac app is unrelated to the CREWTOWER brand of power tools.

It is not a cloud service, an IDE, a terminal emulator, a model, or a hosted agent runner. Nothing it reads leaves the Mac. Core functions: - Show every running agent session in the notch: what it is doing, how long it has been going, and which ones are waiting on a human. - Answer permission requests, questions, and plan approvals directly from the notch panel, without focusing the terminal and without sending a keystroke. - Flag destructive shell commands on the card before you press anything. - Jump to the exact terminal window, tab, or split pane a session belongs to. - Show how much of your subscription window is left: the session window and the weekly window, as a percentage used with a reset countdown. For Claude Code this comes from Anthropic's own usage endpoint using your existing Claude Code login, so it is the provider's number rather than an estimate parsed from local files. For Codex it comes from the CLI's own rate limit reporting. - With the beta Tell Claude plugin on, show what the current Claude Code session has cost so far (Claude Code's own /cost figure, at API prices); no token or cost history is kept. - Show how much context a session has left, for the agents that report it (Claude Code, Codex, Gemini CLI, Qwen Code and opencode; not Cursor), so a compaction stops being a surprise. On Claude Code cards the percentage says "compact soon" at a task break once a long conversation passes the point where quality can start to slip, and an hourglass shows when the prompt cache is about to expire. - Codex usage, including Codex full resets, also shows when Codex runs only inside the ChatGPT app. - Filter the open notch to Unread (questions, failures, and finished work not yet looked at), and mark every finished session read at once, with Undo. - When the notch opens by itself for a finished session, a question, or a failure, it shows that session's card first instead of the whole list. - Answer several waiting permission requests on one card, each on its own or with Allow all, which lists exactly what it covers first. - In beta, off until turned on: send a Claude Code session its next prompt from its card, stop the running turn, compact it, and see a live breakdown of its context, in the terminal and in Claude Desktop's Code tab. It installs a small Claude Code plugin, a mod, through your own claude command line, and needs Claude Code 2.1.287 or newer (2.1.286 in Claude Desktop). The plugin talks only to the app, over a local Unix socket, submits a prompt through Claude Code's own mods API rather than as keystrokes, and never answers a permission prompt. Turning it off uninstalls it. ## Main Claim CrewTower removes the need to watch terminals. A permission request reaches you wherever you are, and your answer resolves it in place. What CrewTower can do for a given session depends on what that agent exposes: a visible session does not imply CrewTower can answer its prompts. ## How the decision path works An agent's hook blocks on a local Unix socket while it waits for a decision. CrewTower answers over that same socket, so approving from the notch never focuses the terminal and never types anything. There is deliberately no synthetic-keystroke path in the app. When an agent offers no decision channel, the only fallback is Jump, which focuses the exact terminal window, tab, or pane instead. Ways to approve: the button allows once; the menu beside it allows every permission request for the rest of the session, a grant CrewTower keeps itself rather than a rule in the agent's settings; and for Claude Code, when it proposes a rule for the request, Always allow has Claude Code add that rule to the project's local settings. ## Agents CrewTower recognises twenty-six agents, in two tiers. Speaks natively to, with full status and one-tap approve/deny where the agent exposes it: - Claude Code, from Anthropic - Codex, from OpenAI - Cursor - Gemini CLI, from Google - Qwen Code, from Alibaba - opencode, from opencode.ai Monitors and jumps to (approving stays in the agent; per-agent detail at https://crewtower.app/agents): - Followed live through an observation hook installed into the agent's own config, only when that agent's config folder exists: GitHub Copilot, Factory Droid, Trae, Kiro, Qoder, ZCode, MiMo, CodeBuddy. - Detected while running in a terminal, with Jump to its exact tab: Aider (followed live from its chat history file), Cline, Kilo Code, DeepSeek, Kimi, Mistral, Grok, Amp. - Detected as a running app, with Jump bringing the app forward: Antigravity (with its latest conversation title), Windsurf, Zed, Warp. An agent outside these twenty-six is not detected. ## Terminals Where Jump lands, per terminal: - Terminal: the exact tab - iTerm2: the exact tab and split - Ghostty: the exact tab - WezTerm: the exact pane - Kitty: the exact window or split, when kitty's remote control is on - Warp: the exact tab, through the focus link Warp provides - Alacritty: the window (it has no tabs) - tmux and herdr: the exact pane A terminal with no built-in support can be taught with one line containing placeholders, and a custom rule always beats the built-in one. ## Setup Hooks are configured on first launch; there is no config file to write by hand. Accessibility permission is used for Jump in the terminals that need it (Ghostty, Alacritty and the window-title fallback) and to tell whether you are already looking at a session, so the notch can stay quiet. Approving from the notch never needs it. ## Privacy Your code, your prompts and your agent transcripts never leave your Mac. Sessions are read from what the agents already write locally, and decisions travel over a local Unix socket. There are no accounts, no analytics, no crash reporting and no tracking in the app. The optional Claude Code plugin behind Tell Claude talks only to the app, over a local Unix socket, and makes no network request. Exactly three features make a network request, and the privacy page lists all three: the optional usage meter, which calls Anthropic using your own existing Claude Code login to read your subscription window; license activation, which talks to us and to our payment provider; and update checks. The usage meter is on by default and can be turned off. Full detail: https://crewtower.app/privacy ## What CrewTower is not - Not a token or cost tracker. It shows how much of your subscription window is left and keeps no token or cost history by day, session or model. The one cost figure it can show is the current Claude Code session's running total (Claude Code's own /cost figure, at API prices), and only with the beta Tell Claude plugin turned on. For that, ccusage is the tool people use. - Not a terminal emulator or a replacement for one. - Not a cloud dashboard: there is nothing to log into and no session is visible from another machine. - Not a way to run agents. It watches and answers agents you started yourself.
