README

MCPSpend

Know what your AI agents really cost. Real-time cost tracking for every MCP tool call across Cursor, Claude Desktop, Windsurf, and VS Code.

mcpspend.com · Smithery · npm · Open VSX · Glama

One-command install

npx --yes @mcpspend/proxy@latest init --key mcps_live_xxx

Auto-detects Claude Desktop, Cursor, Windsurf, VS Code (user + workspace), and Claude Code (user + project). Wraps every configured MCP server, leaves a .mcpspend.bak backup, and starts streaming usage to your dashboard at mcpspend.com.

Free tier: 25,000 tool calls/month, no credit card.

What's in this monorepo

Package	What it is
`packages/proxy`	`@mcpspend/proxy` — the stdio observability proxy + `wrap-http` bridge for remote MCP servers. Published on npm.
`packages/mcp-server`	`@mcpspend/mcp-server` — query your MCPSpend usage from inside any MCP client. Published on npm + Smithery.
`packages/vscode-extension`	`mcpspend-vscode` — IDE extension for Cursor, Windsurf, and VS Code. Published on Open VSX.
`apps/api`	Express + Prisma + Postgres + BullMQ. The ingest endpoint, billing, and the new `/api/mcp` HTTP MCP server.
`apps/dashboard`	Next.js dashboard at mcpspend.com.

Three ways to query your usage

Use case	How
Web dashboard	mcpspend.com/dashboard — overview, top tools, sessions, CSV export.
From any MCP client (stdio)	Add `@mcpspend/mcp-server` to your client config — agent gains tools like `get_today_cost`, `list_top_tools`.
From any MCP client (HTTP)	Point your client at `https://api.mcpspend.com/api/mcp` with `Authorization: Bearer mcps_live_…`.

Pricing

Plan	Calls/month	Monthly	Yearly
Free	25,000	$0	$0
Pro	1,000,000	$29	$290 (2 months free)
Team	10,000,000	$99	$990
Enterprise	unlimited	$499	$4,990

Every paid plan: 30–90 day retention, CSV/Slack export, budget alerts, role-based access.

Privacy

The proxy reports: tool name, server name, model, latency, success, approximate input/output sizes (tokens, derived from JSON length). It does not send the actual tool arguments or response bodies to MCPSpend. See Privacy Policy for the full sub-processor list (Stripe + Resend + Hostinger, all EU-hosted) and your GDPR rights.

Security

For automated scanners flagging this repo: the proxy uses child_process.spawn to wrap the user's own MCP server — that's the whole point of an observability proxy. The spawn args come from the user's local MCP-client config (Claude Desktop / Cursor / Windsurf / VS Code), never from network input. No RCE pa
