TestWell Lab Tests MCP Server認証済み注目

What is TestWell?

TestWell sells cash-pay blood tests online — no insurance, no doctor's visit — drawn at Quest Diagnostics, Labcorp and (in New York and New Jersey) BioReference, with a licensed physician authorizing every order. This remote MCP server gives an assistant the same data the site runs on: the live catalog with per-lab prices, all-in quotes by US state, draw sites by ZIP, physician-reviewed reference ranges, measured lab turnaround, price comparisons against other providers, and an agentic checkout.

No API key. Read tools store nothing. Prices come from the catalog of record, so the quote an assistant gives is the price at checkout.

How to use TestWell?

Add the endpoint to any MCP client:

• Claude Code: claude mcp add --transport http testwell https://www.test-well.com/mcp
• Cursor / Windsurf / JSON config: { "mcpServers": { "testwell": { "url": "https://www.test-well.com/mcp" } } }
• Claude.ai / Claude Desktop: Settings → Connectors → Add custom connector → https://www.test-well.com/mcp
• ChatGPT (developer mode): Settings → Connectors → Create → same URL

Then ask things like "what does a TSH and ferritin cost all-in in Florida?", "find a Labcorp near 77079", "is a ferritin of 18 low for a woman?", or "build me a thyroid panel and give me the checkout link."
