LangCare MCP FHIR Server

Enterprise-grade MCP Server for FHIR-based EMRs, designed for robust deployments in agentic AI platforms. Fully written in Go with enterprise-grade security and generic FHIR operations that work with any FHIR R4 resource type. Supports EPIC, Cerner, OpenEMR, GCP Healthcare API, and any generic FHIR R4 server. Ships with a 40+ Clinical Skills Library — agent-agnostic workflow guides covering medication management, lab interpretation, clinical decision support, documentation, population health, and more. ⭐ New: LangCare now supports MCP Apps — interactive clinical UIs embedded directly in the server. Learn more. ⭐ New: Healthcare Voice Agent — real-time voice AI that lets patients ask about their health records and get spoken answers from their EMR, powered by PipeCat + LangCare MCP. ⭐ New: LangCare CLI — a Python CLI that wraps FHIR tools (fhir_search, fhir_read, fhir_create, fhir_update) over HTTP for AI agent frameworks that don't speak MCP natively (LangChain, smolagents, CrewAI, AutoGen). Handles MCP session handshake internally, outputs clean JSON to stdout.

Quick Configuration

LangCare MCP FHIR connects Claude to your FHIR-based EMR system. You need a YAML configuration file pointing to your backend.

1. Get a Config Template

Choose your backend:

• EPIC: config.epic.example.yaml
• Cerner: config.cerner.example.yaml
• OpenEMR: config.openemr.example.yaml
• GCP Healthcare API: config.gcp.example.yaml
• Any FHIR R4 Server: config.base.example.yaml

2. Configure Claude Desktop

Add to your Claude Desktop config file (~/.config/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "langcare-mcp-fhir": {
      "command": "langcare-mcp-fhir",
      "args": ["-config", "/path/to/your/config.yaml"]
    }
  }
}

On macOS, the config is typically at:

~/Library/Application\ Support/Claude/claude_desktop_config.json

3. Restart Claude Desktop

Close and reopen Claude Desktop. The FHIR tools will now be available.
