Model Context Protocol

Healthcare pricing tools for AI

Connect Claude and other AI assistants to real hospital pricing data, provider directories, and procedure code lookups through MCP.

Get started View tools

Loa Care's MCP server (loa-healthcare) is a remote Model Context Protocol server that gives AI assistants like Anthropic's Claude access to U.S. healthcare pricing data sourced from over 6,000 hospital Machine Readable Files (MRFs) published under the federal Hospital Price Transparency Rule. It provides 7 read-only tools for searching medical procedure codes, finding healthcare providers via the NPI Registry, and comparing cash-pay and insurance-negotiated prices across hospitals. All data returned is publicly available—no Protected Health Information (PHI) is involved.

Data and privacy

All data returned by MCP tools is publicly available healthcare pricing and provider information. No Protected Health Information (PHI) is transmitted through the MCP integration.

Loa Care's MCP tools only process the specific query parameters you submit and do not access, collect, or store any conversation context, chat history, or extraneous data from the AI platform.

We collect basic usage analytics (tool name, request duration, success/failure) for rate limiting and service improvement. These analytics are not associated with conversation content.

Frequently asked questions

What is the Loa Care MCP server?

Loa Care's MCP server is a remote Model Context Protocol integration that lets AI assistants like Claude search medical procedure codes, find healthcare providers, and compare hospital pricing in real time. It connects to Loa Care's database of pricing data from over 6,000 U.S. hospitals.

Where does the pricing data come from?

Pricing data is sourced from hospital Machine Readable Files (MRFs) that U.S. hospitals are required to publish under the federal Hospital Price Transparency Rule (45 CFR 180). This includes gross charges, cash/self-pay rates, and payer-specific negotiated rates. Provider data comes from the CMS National Plan and Provider Enumeration System (NPI Registry).

Do I need an account to use the MCP tools?

Most tools work without an account, with a limit of 50 calls per day. The suggest_procedures tool requires authentication. Creating a free Loa Care account gives you higher rate limits and access to all tools.

Does the MCP server access my conversation history?

No. Loa Care's MCP tools only receive the specific query parameters for each tool call (such as a CPT code or ZIP code). The server does not access, collect, or store any conversation context, chat history, or other data from the AI platform.

Is any personal health information (PHI) involved?

No. All data returned by the MCP tools is publicly available healthcare pricing, hospital, and provider directory information. No Protected Health Information is transmitted through the integration.

Which AI platforms are supported?

The server uses the open Model Context Protocol (MCP) standard and works with any compatible client, including Claude Desktop, Claude.ai, and other MCP-enabled AI applications. The server endpoint is https://www.loacare.com/api/mcp.
