Query Live AI Inference Pricing with the ATOM MCP Server

If you've ever tried to compare LLM pricing across vendors you know how painful it is. One charges per token, another per character, another per request. Cached input discounts exist but good luck finding them. Context window pricing is buried. And by the time you've normalized everything into a spreadsheet something changed on a pricing page and your numbers are stale. This is the problem ATOM was built to solve. It tracks 2,583 SKUs across 47 vendors, normalizes everything to a common unit, and exposes it all through an MCP server your agents can query directly. Here's how to set it up and what you can actually do with it. What MCP gives you here Model Context Protocol lets AI agents connect to external data sources through a standardized interface. Claude, Cursor, Windsurf and others support it natively. Instead of pasting a pricing table into your prompt and hoping it's current, you give your agent a live connection to the source. It queries, reasons, and acts on real numbers. Sett
