At a Glance & Executive Verdict
Omop MCP
Biology, Medicine and Bioinformatics · Local stdio
Quality: 36/100 (Fair) | Auth: API Key required
Fhir MCP Server
Biology, Medicine and Bioinformatics · Local stdio
Quality: 65/100 (Great) | Auth: API Key required
Verdict Summary: Choose Omop MCP if you need specialized Biology, Medicine and Bioinformatics tools running via a local process. Choose Fhir MCP Server if your workspace requires Biology, Medicine and Bioinformatics integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.

get_capabilities
Retrieves metadata about a specified FHIR resource type, including its supported search parameters and custom operations.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Omop MCP is categorized under Biology, Medicine and Bioinformatics and uses a local stdio subprocess. In contrast, Fhir MCP Server belongs to Biology, Medicine and Bioinformatics using local stdio subprocess. Select Omop MCP when you need capabilities focused on biology, medicine and bioinformatics and Fhir MCP Server when you require tools for biology, medicine and bioinformatics.
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.
