FHIR MCP Server

Name: FHIR MCP Server MCP Server
Author: the-momentum

por the-momentum · the-momentum/fhir-mcp-server

Query and write to any FHIR-compliant healthcare server via MCP.

FHIR (Fast Healthcare Interoperability Resources) is the standard API for clinical data. This MCP lets Claude query any FHIR server — patient records, observations, medications — and follow the spec's resource references like a real EHR app.

      "command": "uvx",
      "args": [

  }
}

Cursor usa el mismo esquema mcpServers que Claude Desktop. La configuración del proyecto prevalece sobre la global.

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "fhir-mcp-server": {
      "command": "uvx",
      "args": [
        "fhir-mcp-server"
      ]
    }
  }
}

Haz clic en el icono MCP Servers de la barra lateral de Cline y luego en "Edit Configuration".

~/.codeium/windsurf/mcp_config.json

  "mcpServers": {
    "fhir-mcp-server": {
      "command": "uvx",
      "args": [
        "fhir-mcp-server"
      ]
    }
  }
}

Mismo formato que Claude Desktop. Reinicia Windsurf para aplicar.

~/.continue/config.json

{

      "command": "uvx",
      "args": [
        "fhir-mcp-server"
      ]
    }
  ]
}

Continue usa un array de objetos de servidor en lugar de un mapa.

      }
    }
  }
}

Añádelo a context_servers. Zed recarga en caliente al guardar.

Un solo comando. Verifica con claude mcp list. Quita con claude mcp remove.

Casos de uso

Usos del mundo real: FHIR MCP Server

Build a chronological clinical timeline for one patient

👤 Clinical informatics, research teams ⏱ ~15 min intermediate

Cuándo usarlo: You need a summary of one patient's encounters, meds, and labs across visits.

Requisitos previos

Server/skill installed and authenticated — See repo README

Flujo

Get the patient

Find Patient with identifier MRN-12345 and return name, DOB, and active conditions.✓ Copiado

→ One Patient + Condition list
Build the timeline

Retrieve all Encounters and MedicationRequests for that patient in the last 12 months. Sort chronologically and summarize.✓ Copiado

→ Time-sorted list with encounter type + meds prescribed

Resultado: A clinician-readable summary you can paste into a chart note.

Errores comunes

Real PHI — Real PHI — never connect this to a chat that's also pasting screenshots to a third-party service. Use a HIPAA-compliant Claude deployment.

Most FHIR servers use SMART-on-FHIR. Generate a token via your EHR's auth flow and set FHIR_TOKEN.

Verificar: fhir_search Patient?_count=1 returns a Bundle

Unsupported resource type

Different servers implement different subsets. Check the CapabilityStatement: GET /metadata.

Verificar: Confirm the resource type is in CapabilityStatement.rest.resource
