Medical Cost Data for AI Assistants
Give Claude, ChatGPT, and other AI assistants direct access to 21,000+ medical procedure costs, drug prices, and injury treatment estimates using the Model Context Protocol.
What is MCP?
The Model Context Protocol (MCP) is an open standard that lets AI assistants connect to external data sources and tools. Instead of pasting data into a chat, the AI can directly query our medical costs database to answer your questions with real, cited data.
Real-Time Lookups
Ask Claude "How much does a knee MRI cost?" and get actual Medicare rates, not hallucinated numbers.
State Comparisons
Compare costs across states and see how geographic factors affect pricing.
Government Data
All costs from CMS Medicare fee schedules, CDC, and NHTSA -- not estimates or guesses.
