This is a Cloudflare Workers-based server that tracks AI API rate limits, deployed as both a REST API and MCP endpoint. The documentation is minimal, but the setup suggests it monitors usage across various AI providers to help you stay within quota boundaries. You'd reach for this if you're juggling multiple AI services and need centralized visibility into your remaining rate limit headroom. It runs on Cloudflare's edge network at api.lazy-mac.com, so requests should be fast regardless of where Claude is operating. The dual REST and MCP interface means you can query it programmatically outside of Claude conversations if needed.
