Overview

claudeusage-mcp

An MCP server that gives you real-time visibility into your Claude Pro/Max subscription usage — directly inside Claude Code.

No API keys. No scraping. No browser automation. It reads the OAuth token that Claude Code already stores on your machine and calls Anthropic's usage endpoint to get the exact same data shown on claude.ai/settings/usage.

What it shows

Metric	Description
Current Session	5-hour burst window utilization with reset countdown
Weekly Usage - All Models	7-day rolling limit across all models
Weekly Usage - Opus Only	7-day Opus-specific usage (Max plans)
Weekly Usage - Sonnet Only	7-day Sonnet-specific usage
Extra Usage	Enabled/disabled, monthly limit, credits used

(live data)

Rate-limited state

When any metric hits 100%, the output changes to show reset date and time:

Weekly Usage - All Models (7-day) [RATE LIMITED]
  XXXXXXXXXXXXXXXXXXXX  100%
  Resets in 1d (Mon Mar 24 05:00PM)

Statusline output

The included statusline script adds a third line to your Claude Code status bar with progress bars and color coding:

  Usage: Session █░░░░░░░░░ 13% | Weekly █████████░ 94% | Sonnet █░░░░░░░░░ 8%

When rate-limited:

  Usage: Session: RATE LIMITED, Resets in: 3h 37m (Sun Mar 22 07:59PM) | Weekly: RATE LIMITED, Resets in: 1d (Mon Mar 23 05:00PM)

Color grading

Range	Color	Status
0-49%	Green	Safe
50-79%	Orange	Moderate
80-99%	Red	High
100%	Red + text	RATE LIMITED with reset datetime

Tools

Tool	Purpose
`get_usage`	Full dashboard — session, weekly, per-model, extra usage with progress bars
`get_session_usage`	Current 5-hour session window only
`get_weekly_limits`	7-day limits with per-model breakdown (All, Opus, Sonnet)
`check_rate_status`	Am I about to be rate-limited? Returns LOW / MODERATE / HIGH / RATE LIMITED

Requirements

Node.js >= 18
Claude Code logged in with a Pro or Max subscription
macOS or Linux (reads credentials from Keychain or ~/.claude/.credentials.json)

Installation

Option 1: `claude mcp add` (recommended)

git clone https://github.com/OrelliusAI/claudeusage-mcp.git
cd claudeusage-mcp
npm install && npm run build

claude mcp add claudeusage -- node $(pwd)/dist/index.js

Restart Claude Code. Then ask "what's my usage?" or type /usage.

Option 2: Manual config

git clone https://github.com/OrelliusAI/claudeusage-mcp.git
cd claudeusage-mcp
npm install && npm run build

Add to your MCP config (.claude.json or project .mcp.json):

{
  "mcpServers": {
    "claudeusage": {
      "command": "node",
      "args": ["/absolute/path/to/claudeusage-mcp/dist/index.js"]
    }
  }
}

Optional: Statusline integration

Add usage data to your Claude Code statusline (always visible at the bottom):

# If you DON'T have a statusline yet:
cp statusline.sh ~/.claude/usage-statusline.sh
chmod +x ~/.claude/usage-statusline.sh

Then set in ~/.claude/settings.json:

{
  "statusLine": {
    "type": "command",
    "command": "bash ~/.claude/usage-statusline.sh"
  }
}

If you already have a statusline, use statusline-combined.sh instead — it pipes your existing statusline and appends the usage line.

How it works

Claude Code (your session)
    |
    |-- Reads OAuth token from:
    |   |-- macOS Keychain ("Claude Code-credentials")
    |   +-- ~/.claude/.credentials.json (Linux/WSL)
    |
    |-- Calls: GET https://api.anthropic.com/api/oauth/usage
    |   Headers: Authorization: Bearer <your-oauth-token>
    |            anthropic-beta: oauth-2025-04-20
    |
    |-- Caches response for 60 seconds
    |   +-- On 429 (rate limit): serves stale cache
    |
    +-- Returns formatted usage data via MCP tools

Zero configuration. The OAuth token is created automatically when you sign into Claude Code with your Pro/Max subscription. No API keys, no environment variables, no .env files.

Authentication

This server uses the same OAuth token that Claude Code creates when you log in:

Platform	Location
macOS	Keychain (service: `Claude Code-credentials`)
Linux / WSL	`~/.claude/.credentials.json`

Required OAuth scopes: user:inference, user:profile

Token issues?

If the server reports authentication errors:

Your token may be expired — restart Claude Code to trigger a fresh OAuth login
Token created via claude setup-token or /login may have wrong scopes — delete credentials and restart Claude Code

Do NOT use API keys (sk-ant-api...). This server is for Pro/Max subscribers, not API users.

Rate limiting

Anthropic's /api/oauth/usage endpoint is aggressively rate-limited. This server handles it:

Caching — responses cached for 60 seconds (MCP) or 120 seconds (statusline)
Stale fallback — on 429, the last successful response is served
Graceful errors — clear messages when the API is unavailable

Who is this for?

Claude Pro and Max subscribers who use Claude Code and want to see their plan usage without opening a browser. This is not for API users — if you have an API key (sk-ant-api...), use the Usage and Cost API instead.
