Overview
Description from the maker (original English)
Built into the Actvt Mac app: live system metrics, ports, and Claude Code, Codex and pi sessions.

Common questions
Is Actvt safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.4.11) reached the registry yesterday.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code.
What can I use instead?

Actvt A macOS app that monitors your Mac and your AI coding agents in one place.
Website · Docs · Changelog · Roadmap
Actvt shows live CPU, GPU, memory and network for your Mac. It also reads the Claude Code and Codex session transcripts already sitting on your disk, so you can search them, see what they actually cost, and pick one back up where you left it.
It ships an embedded MCP server, so your agents can query the machine they are running on.
Download
[Download for Apple Silicon](https://actvt.io). Requires macOS 15.5 or later.
Updates are delivered in-app through the Sparkle appcast in this repository, and every version is listed on the releases page.
What it does
System monitoring. CPU, GPU, memory and network with live graphs, usage breakdowns and temperatures. History is persisted across restarts.
Agent sessions. One browser for every Claude Code, Codex and Claude Desktop session. Full transcripts with thinking blocks and tool calls, outline navigation, search across everything, and one-click resume back into your terminal. Sessions are tagged by where they started, so a run in Ghostty is distinguishable from one in Cursor.
Cost and usage analytics. Total spend, token counts, cache hit ratio, spend by project, tool usage, and a daily activity heatmap. Plan usage bars show how much of your Claude and Codex quota is left and when it resets.
Spend is calculated at API token pricing. On a flat-rate plan that figure is not your
bill. It is what those tokens would have cost at API rates, which is a useful read on what
you are getting out of the plan.
Remote sessions. Reach over SSH to other Macs and headless Linux boxes and fold their sessions into the same timeline. Tailscale peers are discovered automatically. Install the helper on each host with one command, no sudo required.
curl -fsSL https://actvt.io/install-cli.sh | shNotifications. Get told when a session is waiting on your input, finishes, errors, runs long, or crosses a cost threshold. Clicking a notification raises the exact terminal or editor window that session lives in.
Sensitive data detection. Transcripts are scanned for emails, credentials, payment cards, IDs and other sensitive spans. Every scan runs on-device and offline. Values are masked by default.
Port manager. List every listening TCP port with the process behind it, and reclaim one without leaving the app.
MCP server
Actvt embeds a Model Context Protocol server. One click connects it to your installed Claude Code and Codex CLIs, after which your agents can ask Actvt about the machine they are running on. The server is local and protected by an auth token.
| Group | What agents can query |
|---|---|
| System | CPU, GPU, memory, network, thermal pressure, uptime, and persisted history |
| Ports | Every listening port and its owning process. port_kill reclaims one. It refuses protected, system and AI-agent processes, and re-verifies the target before acting |
| Agent sessions | Cost and token roll-ups, full-text transcript search, error-pattern triage, and resume cues. Remote-aware, so sessions on your other machines are visible too |
A practical use is diagnosis. An agent can ask whether a slow session was the model thinking or the Mac thermal-throttling, and get an answer grounded in what actually happened.
Raw transcripts stay behind an explicit opt-in, and detected sensitive data is masked.
Privacy
Actvt reads session files that are already on your machine and scans them locally. Sensitive data detection runs entirely on-device with no network access. Remote sessions travel over your own SSH connection, are held in memory while you read them, and are never written to the local index. Plan usage bars read the quota your provider already reports using your CLI's own login, and Actvt never modifies those credentials.
