MCPSpend Cost Tracking Skill
Skill by ara.so — MCP Skills collection.
MCPSpend provides real-time cost observability for Model Context Protocol (MCP) tool calls. It wraps any MCP server as a transparent proxy, attributing spend per tool, project, and customer across Claude Desktop, Cursor, Windsurf, and VS Code.
Installation
One-command setup (recommended)
npx --yes @mcpspend/proxy@latest init --key mcps_live_YOUR_KEY
This auto-detects your MCP clients (Claude Desktop, Cursor, Windsurf, VS Code) and wraps all configured servers. It creates a .mcpspend.bak backup of your original config.
