Last EHR - Medplum MCP Server

Read the chart broadly. Write only what a human approved. Last EHR is the agent layer for a headless FHIR EHR. It does three things, and the write protocol is only one of them. It runs locally over stdio via the published package.

People connecting web framework tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.
