claude-spend
See where your Claude Code tokens go. One command. Local dashboard. No setup.
npx @mpalermiti/claude-spend
Reads your local Claude Code session data (~/.claude/) and shows you exactly where your tokens go. Everything runs locally. Nothing leaves your machine.
The ROI Multiplier
Your Claude Code subscription hides how much API-equivalent value you're actually using. claude-spend reveals it. It detects your plan (Pro, Max 5x, Max 20x) from your local Claude Code config, and the dashboard shows your multiplier — how many times over you're getting your money's worth.
26.7x value from your $200/mo plan
This is the stat that makes you feel good about your subscription. And the one your followers will screenshot.

MCP Server
Add this to ~/.claude/settings.json and Claude can query spend data during any conversation:
{
"mcpServers": {
"claude-spend": {
"command": "npx",
"args": ["@mpalermiti/claude-spend", "--mcp"]
}
}
}
Six tools: get_spend_summary, get_top_sessions, get_project_breakdown, get_insights, get_daily_trend, get_quota. The first five accept optional from/to date params.
Report and Quota Modes
For scripts, cron jobs, and agents that want numbers without a browser:
claude-spend --report --project myapp --trend-days 7 # markdown, grouped by project
claude-spend --report --sessions build#1:<uuid>,build#2:<uuid> # one row per session id
claude-spend --report --from 2026-09-01 --to 2026-09-07 --json # machine-readable
claude-spend --quota # "session 58% · weekly 28%"
--sessions takes label:id pairs (label optional). Subagent and workflow transcripts fold into the session that spawned them, so one row is the whole job. Launch a job with claude -p ... --session-id $(uuidgen) and you can report on exactly that job afterwards.
--quota reads your subscription's rolling windows (5-hour session, 7-day weekly) from the same endpoint Claude Code's /usage uses. It is best-effort and macOS-first (the token lives in the login keychain); --report includes it unless you pass --no-quota.
How It Works
Claude Code writes JSONL session files to ~/.claude/projects/. This tool parses them, calculates API-equivalent costs per model (with cache write/read pricing), aggregates by day/model/project, and generates insights. The cost numbers represent what the usage would cost at API rates — not what you pay on a subscription. That gap is your ROI.
Accuracy notes (3.1): Claude Code writes one JSONL line per content block and repeats the usage on each, so responses are deduped by message id. Transcripts nested under <session>/subagents/** (including workflow agents) are read and attributed to their parent. Pricing covers the Claude 5 family (Opus 5, Sonnet 5, Fable 5.1) and prices 1-hour cache writes at 2× input, which is what Claude Code uses. Set CLAUDE_CONFIG_DIR to point at a different data dir.
Origin
Forked from claude-spend by Aniket Parihar. I kept the core JSONL parser concept, then rebuilt everything else: the dashboard, date filtering, analytics engine, insights, drill-downs, heatmap, share card, keyboard nav, MCP server, and the design. MIT license.
