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. Select your plan ($100 or $200/mo), 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.

Keyboard Shortcuts

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"]
    }
  }
}

Five tools: get_spend_summary, get_top_sessions, get_project_breakdown, get_insights, get_daily_trend. All accept optional from/to date params.

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.

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.
