A Model Context Protocol (MCP) server that provides access to Medplum FHIR healthcare data. It enables Claude and other MCP clients to read, search, and query FHIR resources from one or more Medplum environments.
Features
Multi-environment support — connect to multiple Medplum projects (e.g. dev, staging, production) and switch between them per request
30 FHIR resource types — Patient, Practitioner, Observation, Condition, MedicationRequest, and more
Search with parameters — query resources using standard FHIR search parameters
Resource history — view version history of any resource with pagination

| Read a single FHIR resource by type and ID |
| Search for FHIR resources with query parameters |
| Get version history of a resource |
Setup
Install
npm install @ncodeuy/medplum-mcpConfigure
Set one environment variable per field, using the pattern MEDPLUM_PROJECT_<NAME>_<FIELD>:
# Required
MEDPLUM_PROJECT_STAGING_CLIENT_ID=staging-client-id
MEDPLUM_PROJECT_STAGING_CLIENT_SECRET=staging-secret
# Optional (defaults to https://api.medplum.com/)
MEDPLUM_PROJECT_STAGING_BASE_URL=https://staging.example.com/
MEDPLUM_PROJECT_STAGING_PROJECT_ID=proj-staging
# Add more projects by changing the name segment
MEDPLUM_PROJECT_PRODUCTION_CLIENT_ID=prod-client-id
MEDPLUM_PROJECT_PRODUCTION_CLIENT_SECRET=prod-secret
# Optional — defaults to the first project found
MEDPLUM_DEFAULT_PROJECT=stagingYou can also use the MEDPLUM_PROJECTS environment variable with a JSON object:
MEDPLUM_PROJECTS='{
"staging": {
"baseUrl": "https://staging.example.com/",
"clientId": "staging-client-id",
"clientSecret": "staging-secret",
"projectId": "proj-staging"
},
"production": {
"clientId": "prod-client-id",
"clientSecret": "prod-secret"
}
}'Flat env vars take priority when both are set.
