Purpose
This is a lightweight macOS menu bar application that monitors and displays usage limits for AI coding assistants like Claude Code, Codex CLI, and Cursor.

Security Assessment
The application accesses sensitive data by reading local authentication tokens and SQLite databases to function as intended. However, the automated code scan of 12 files found no dangerous patterns, no hardcoded secrets, and no excessive or dangerous permissions requested. The README clearly states that no API keys are needed, as it simply reads existing local credentials. The app is not currently notarized by Apple, which is a minor security consideration requiring a manual gatekeeper bypass to run. Overall risk is rated as Low.

Quality Assessment
The project is actively maintained, with the most recent push occurring today. It uses a standard permissive MIT license. The primary concern is its low visibility and community trust level; it currently has only 5 GitHub stars and a relatively unknown developer footprint. Being a native Swift application built with SwiftUI for macOS 13.0+, it is a focused desktop utility rather than an expansive or complex system.

Verdict
Safe to use, though users should be aware of the tool's low community visibility and the manual system permission bypass required for the non-notarized pre-built binary.

Installation

Homebrew (Recommended)

brew tap shipshitdev/tap
brew install --cask meterbar

To update:

brew upgrade --cask meterbar

Manual Download

Download the latest release from the Releases page.

Note: Since the app isn't notarized, you may need to right-click and select "Open" the first time, or run:

xattr -cr /Applications/MeterBar.app

Build from Source

Prerequisites: macOS 13.0+, Xcode 15.0+

git clone https://github.com/shipshitdev/meterbar.app.git
cd meterbarapp
open MeterBar.xcodeproj
# Build and run (Cmd+R)

Setup

Claude Code

  1. Install Claude Code CLI: npm install -g @anthropic-ai/claude-code
  2. Log in: claude login
  3. The app automatically reads credentials from ~/.claude/

Codex CLI

  1. Install Codex CLI: npm install -g @openai/codex
  2. Log in: codex login
  3. Select your team/workspace when prompted
  4. The app automatically reads credentials from ~/.codex/auth.json

Cursor

  1. Install and log into Cursor IDE
  2. The app automatically reads from Cursor's local database

Usage

  1. Launch the app - It appears in your menu bar
  2. Click the icon - See all your usage metrics
  3. Click a card header - Expand/collapse to see details
  4. Refresh - Click the refresh icon to update metrics

Understanding the Display

Collapsed view: Shows service name + compact progress bar for quick status

Expanded view: Shows detailed metrics:

  • Usage percentage and progress bar
  • Reset time (when limits refresh)
  • Subscription type badge

Status Colors

Color Meaning
Green < 50% used - plenty remaining
Yellow 50-80% used - approaching limit
Red > 80% used - near or at limit

CLI Tool

MeterBar includes a command-line tool for scripts and automation.

# Show current usage
meterbar usage

# JSON output for scripts
meterbar usage --json

# Filter by provider
meterbar usage --provider claude

# Show token costs (last 30 days)
meterbar cost

# Cost for specific period
meterbar cost --days 7 --json

The CLI is automatically installed when using Homebrew. For manual installs, it's located at:

/Applications/MeterBar.app/Contents/Helpers/meterbar

How It Works

MeterBar reads authentication tokens from local files created by CLI tools:

~/.claude.ai/            # Claude Code OAuth
~/.codex/auth.json       # Codex CLI OAuth
~/Library/Application Support/Cursor/  # Cursor local DB

It then calls the respective APIs to fetch current usage data:

  • Claude: https://api.anthropic.com/settings/usage
  • Codex: https://chatgpt.com/backend-api/wham/usage
  • Cursor: Local SQLite queries

No API keys are stored - the app uses the same OAuth tokens as the CLI tools.

Privacy & Security

  • All credentials remain in their original locations (managed by CLI tools)
  • No data sent to external servers (only official API calls)
  • Sandboxed app with minimal file system access
  • Open source for full transparency

Architecture

  • SwiftUI - Modern declarative UI
  • Combine - Reactive data flow
  • App Sandbox - Secure with specific entitlements for credential access
  • URLSession - Native networking

Troubleshooting

"Not configured" for a service

Make sure you're logged into the CLI tool:

claude login   # For Claude Code
codex login    # For Codex CLI

Codex showing "Free" instead of Team

Run codex logout && codex login and select your team workspace when prompted.

App can't read credentials

The app needs sandbox exceptions to read CLI credential files. Rebuild from source if using a modified entitlements file.
