MCPSpend — know what every MCP tool call costs you (launching tomorrow)

Solo founder launch tomorrow 🚀

MCPSpend is the cost-attribution layer for AI agent tooling. If you
use Cursor, Claude Desktop, Windsurf, or VS Code with MCP servers
(filesystem, GitHub, Playwright, Figma-remote, anything), MCPSpend
tracks every tool call: cost, latency, tokens, success/fail.

Install is one command, auto-detects every MCP client on your machine:
   npx --yes @mcpspend/proxy@latest init --key mcps_live_xxx

→ Free tier: 25k calls/month, no credit card
→ Pro: $29/mo (or $290/yr — 2 months free)
→ Open source proxy on npm, IDE extension on Open VSX, MCP server on
  Smithery

Why I built it: my Cursor + Claude bill ran 7x in three months and the
Anthropic console showed me a number but no breakdown. So I built the
observability layer I wished existed.

What's already live:
✅ @mcpspend/proxy on npm (v0.5.0)
✅ @mcpspend/mcp-server (query your usage from inside the chat)
✅ mcpspend-vscode on Open VSX (Cursor + Windsurf compatible)
✅ Stripe billing, monthly/yearly, cancel anytime
✅ Dashboard at mcpspend.com

Launching tomorrow at 12:01 PT. Would mean a lot if you set a
notification on the listing. Roast me hard in the comments — solo
founder, any feedback helps.
