Fhir MCP Server Tools (13)
get_capabilities
Retrieves metadata about a specified FHIR resource type, including its supported search parameters and custom operations.
type
The FHIR resource type name (e.g., "Patient", "Observation", "Encounter")
search
Executes a standard FHIR search interaction on a given resource type, returning a bundle or list of matching resources.
searchParam
A mapping of FHIR search parameter names to their desired values (e.g., {"family":"Simpson","birthdate":"1956-05-12"}).
response_filter_fhirpaths
(Optional) An array of FHIRPath expressions (e.g., `["Patient.name", "Patient.birthDate", "Bundle.link.where(relation='next').url"]`) to apply to the resources in the response bundle.
read
Performs a FHIR "read" interaction to retrieve a single resource instance by its type and resource ID, optionally refining the response with search parameters or custom operations.
id
The logical ID of a specific FHIR resource instance.
operation
The name of a custom FHIR operation or extended query defined for the resource (e.g., "$everything").
create
Executes a FHIR "create" interaction to persist a new resource of the specified type.
payload
A JSON object representing the full FHIR resource body to be created.
update
Performs a FHIR "update" interaction by replacing an existing resource instance's content with the provided payload.
delete
Execute a FHIR "delete" interaction on a specific resource instance.
