Why?

Every developer using AI agents worries about spending. Most tools don't tell you what each message costs until the bill arrives.

This MCP server tracks it in real time — per message, per model, per day. Set a budget, get alerts, see exactly where your money goes.

• Budget alerts — warns when approaching daily/monthly limits
• Cost reports — today, this week, this month, all time
• Model breakdown — donut chart showing which model eats your budget
• Spending trends — 14-day bar chart with color-coded spending
• 15+ models supported — Cursor, GPT, Cursor, Cursor, Llama
• Estimate before running — check cost before expensive tasks
