openemr-mcp

Model Context Protocol (MCP) server for OpenEMR — connect any MCP-compatible AI assistant (Claude Desktop, Cursor, VS Code Copilot) directly to your OpenEMR instance.

Features

17 MCP tools covering:

All tools work in mock mode out of the box — no OpenEMR installation required for evaluation.

Quick Start

Install

pip install openemr-mcp
# or with uv:
uv add openemr-mcp

Run (stdio transport)

# Mock mode — no OpenEMR needed
OPENEMR_DATA_SOURCE=mock openemr-mcp

# Against a live OpenEMR FHIR API
OPENEMR_DATA_SOURCE=api \
  OPENEMR_API_BASE_URL=https://your-openemr/apis/default \

Claude Desktop Configuration

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "openemr": {
      "command": "uvx",
      "args": ["openemr-mcp"],
      "env": {
        "OPENEMR_DATA_SOURCE": "api",
