Costkits MCP server

CostKits MCP Server

Give Claude, ChatGPT, Cursor, and other MCP clients access to live US healthcare cost data.

CostKits provides procedure cost estimates, patient out-of-pocket calculations, provider pricing, insurance coverage rules, and medical bill analysis using hospital-transparency and CMS data rather than model memory.

Ask healthcare cost questions in natural language. CostKits supplies the structured data and calculations.

A thin Model Context Protocol server for the CostKits API.

What can an agent do with CostKits?

Ask questions such as:

• "What would a colonoscopy cost in Connecticut?"
• "How much would I owe if I have $500 left on my deductible and 20% coinsurance?"
• "Compare MRI prices from providers near Dallas."
• "Does this procedure commonly require prior authorization?"
• "Do these medical bill line items show possible duplicate or unbundled charges?"
• "Resolve 'knee scan' to the correct procedure and estimate the cost."

The MCP server selects the appropriate CostKits API tools and returns structured healthcare cost data the model can explain to the user.
