FHIR Server

A comprehensive Model Context Protocol (MCP) server that provides FHIR (Fast Healthcare Interoperability Resources) functionality with advanced data quality assessment and error handling capabilities.

🎯 Overview

This MCP server bridges the gap between AI applications and FHIR healthcare data systems, providing robust tools for accessing patient information, clinical data, and assessing data quality across different FHIR servers. Perfect for healthcare AI development, clinical research, and testing FHIR implementations.

✨ Key Features

🏥 Comprehensive FHIR Resource Access

• Patient Management: Search, retrieve, and analyze patient demographics
• Clinical Data: Access observations, conditions, medications, diagnostic reports
• Care Coordination: Retrieve care plans and treatment information
• Server Capabilities: Query FHIR server metadata and supported features

🔍 Advanced Data Quality Assessment

• Quality Scoring: 0-100 data quality scores for FHIR servers
• Integrity Checks: Detect orphaned references and disconnected data
• Validation: Comprehensive FHIR response validation
• Issue Detection: Identify data consistency problems automatically

🛡️ Enhanced Error Handling

• HTTP Status Handling: Proper 404, 401, 403, timeout responses
• FHIR OperationOutcome: Standards-compliant error reporting
• Detailed Logging: Request/response debugging information
• Graceful Degradation: Continues operation despite server issues

🧰 Developer-Friendly Tools

• Async Architecture: High-performance async/await implementation
• Pagination Support: Handle large datasets efficiently
• Flexible Configuration: Environment-based server configuration
• MCP Integration: Seamless Claude Desktop integration

🚀 Quick Start

Prerequisites

• Python 3.11 or newer
• Claude Desktop (for MCP integration)

Installation

1. Clone the repository

   git clone https://github.com/jcafazzo/fhir-mcp.git
   cd fhir-mcp
   

2. Install dependencies

   pip install -r requirements.txt
   

3. Configure Claude Desktop

         "command": "python3",
         "args": ["/path/to/fhir-mcp/fhir_mcp_server.py"],
         "env": {
           "FHIR_BASE_URL": "https://r4.smarthealthit.org"
         }
       }
     }
   }
   

4. Restart Claude Desktop

🔒 Security & Privacy

• No PHI Storage: Server operates read-only, no data retention
• Configurable Auth: Support for Bearer token authentication
• Audit Logging: Comprehensive request/response logging
• Error Handling: Secure error responses without data leakage

🧪 Testing

Test Server Quality

# Test different FHIR servers
python3 fhir_mcp_server.py

Use the assess_data_quality tool to evaluate:

• Data completeness (0-100 score)
• Reference integrity
• Resource availability
• Error rates

Synthetic Data Testing

Works excellently with:

• Synthea: Realistic synthetic patient data
• MIMIC-IV FHIR: Real anonymized hospital data
• Custom datasets: Load your own test data
