LLM Token Tracker

LLM Token Tracker is a developer-focused utility that tracks token usage and API costs across multiple major LLM providers (OpenAI, Anthropic/Claude, and Google Gemini). It features MCP (Model Context Protocol) support, enabling integration as either a Node.js library or stand-alone MCP server for real-time, per-user/session tracking, cost calculation, historical usage keeping, and multi-currency (USD/KRW) display. Ideal for AI tool builders wanting transparency on LLM API usage or to pass accurate costs to end users.
