## Description

Stop guessing which textbook option is actually the cheapest. This MCP gives your AI client the ability to crunch the numbers on textbook procurement. Instead of just looking at a sticker price, you can ask your agent to compare the total cost of a rental versus a used copy, or even figure out which option has the lowest daily cost based on how long you need the book. It also checks if you can just head to the library instead of spending any money at all. Whether you are a student trying to stretch a budget or an educator helping students find affordable resources, this tool turns your AI into a specialized procurement assistant that understands the relationship between price, duration of use, and availability.
