Token Meter

A tiny macOS menu bar app that shows how much of your Claude Code usage limits you've used, and when they reset.

• Menu bar percentage for your current 5-hour session, always visible.
• Popover with the session and weekly limits, each with a progress bar (orange above 75%, red above 90%) and a reset countdown.
• Auto-refreshes every 60 seconds. No Dock icon, no window.
• Works with both logins: the terminal claude CLI and Claude in Xcode keep separate logins. Token Meter reads both and uses whichever is still valid.

The numbers are the same ones Claude Code's /usage command shows.

Requirements

• macOS 27 (the project's current deployment target; lower it in the target settings if you need to)
• Xcode to build it
• A Claude Code login (a Pro or Max plan) on this Mac

Build and run

1. Clone the repo and open Token Meter.xcodeproj in Xcode.
2. Press Run.
3. The first time it runs, macOS asks for Keychain access to Claude Code's credentials. Choose Always Allow.

How it works

1. Claude Code stores its OAuth login in the macOS Keychain under Claude Code-credentials (the terminal CLI) and Claude Code-credentials-<hash> (other config directories, such as Claude in Xcode).
2. Token Meter reads every matching item and tries the token that expires last first.
3. It calls Anthropic's usage endpoint (/api/oauth/usage) with that token and decodes the 5-hour and 7-day windows.

The token is only ever sent to api.anthropic.com. It is never written to disk or logged. Token Meter never refreshes tokens itself, so it can't log Claude Code out; it relies on Claude Code keeping its own login fresh.

File	Purpose
UsageService.swift	Keychain access, the usage request, response decoding
UsageStore.swift	Observable state and the 60-second refresh loop
ContentView.swift	The popover UI
MyApp.swift	MenuBarExtra entry point

Caveats

• Unofficial. This is an independent project and isn't affiliated with or endorsed by Anthropic.
• Undocumented endpoint. The usage API isn't a public, supported API and may change or break without notice. If it does, the popover shows "Unexpected response from the usage API."
• App Sandbox is off, because the app needs to read Claude Code's Keychain items. That also means it can't be distributed through the Mac App Store as is.
• If you see "Login expired", every Claude Code login on the Mac has expired. Use Claude Code once (in a terminal or in Xcode) to refresh it.
