Vitals 1.4: an MCP server for Claude, Codex and Cursor

An assistant working on your Mac could always read a thousand process names and guess. Now it can ask Vitals: which app is behind a figure, with every helper counted under it, which project a dev server belongs to and what port it holds, what is misbehaving right now, and what the last 30 days looked like. Every answer says when it was measured.

Nothing changes in how you talk to it. Ask in your own words, and the assistant asks Vitals for what it needs. Some things to try:

• What is slowing my Mac down right now?
• Which app is using the most memory, and is it the tabs or the extensions?
• What is on port 3000, and is it safe to quit?
• Which of my dev servers has nothing used in days?
• What drained the battery this morning?
• Is anything misbehaving on my Mac right now?
• Quit the dev server in storefront-web.

The last one opens a window from Vitals. That is the next section.

1. 01 Open Vitals, then Settings → Integrations.
2. 02 Turn on Let AI Assistants Ask Vitals.
3. 03 Click Add beside each assistant you use: Claude, Claude Code, Codex or Cursor. Vitals puts itself in that assistant’s list of tools, next to any it already has.
4. 04 If the assistant was open, start it again. From then on it can ask Vitals.

• Another assistant that speaks MCP? Click Copy Configuration and paste it where that assistant keeps its tools.
• Remove takes Vitals out of an assistant’s list again.

Ask your assistant to free some memory or stop a forgotten dev server, and it cannot just do it. It asks Vitals, and Vitals opens a window of its own in front of whatever you are doing: what is asking, what it wants to quit, how much memory and which ports that frees, and whether Vitals thinks it is safe.

Click Quit or Don’t Quit. No answer in a minute counts as no, and after a no the assistant leaves it alone. Vitals says no by itself to anything that is part of macOS, to anything that would start again at once, and to itself.

For a project you trust, tick Don’t ask again for safe requests in that folder, and the safe ones go ahead on their own. Safe means nothing of yours is lost: a dev server nothing has used, a process with no window and no open connections. Everything else is still asked about, and a force quit always is.

Settings → Integrations has a switch for each kind of thing an assistant may be told: your Mac’s figures, your apps and processes, your projects and ports, and your history. What is off is simply not told, and an assistant that asks for it is told you turned it off.

Project Folders by Name Only gives a folder as “shop”, never as where it is on your Mac. Vitals itself sends nothing anywhere. What an assistant is told goes wherever that assistant sends its conversations, and that is why these switches exist.

The bottom of Settings → Integrations lists what asked to quit something and what came of it: quit, declined, not answered, or refused by Vitals. Show All opens the whole month, and Clear empties it.
