A Secure Gateway Connecting EHR Data and AI: The Mechanism of the MCP Server
智能EHR MCP服务器 - Glama
Summary
This system is a dedicated server that provides patient data extracted from Electronic Health Records (EHR) to external AI/LLMs via the Model Context Protocol (MCP). This enables AI agents to perform data analysis and searches through standardized, secure interfaces.
Details
This system functions as a 'secure gateway' connecting EHR data with Large Language Models (LLM). The process is three-phased. First, a SMART on FHIR client uses standard protocols to extract structured and unstructured records from the EHR. Second, this MCP server acquires that data and exposes it via the Model Context Protocol (MCP). Third, external AI agents connect to the MCP server and use provided tools (e.g., `grep_record` for full-text search, `query_record` for SQL queries on FHIR structured data, `eval_record` for custom JavaScript execution) to 'query' or analyze the data. This allows the AI to utilize comprehensive patient information (medical history, medication, lab results, etc.) in a secure and standardized manner without direct access to the core EHR system. Developers can implement this using an independent Web client, local CLI-based extraction/server startup, or persistent server via SSE. The goal of this architecture is to balance security and standardization when utilizing medical data with AI.
