Healsens-fhirmcp: Secure FHIR Data Access for AI Agents

Details

healsens-fhirmcp is an open-source, conformance-aware MCP server that helps healthcare systems already exposing FHIR make their data usable by AI agents safely and predictably. Unlike generic HTTP wrappers or thin proxies, this tool embeds version-matched FHIR conformance artifacts and combines them with the live CapabilityStatement of the connected server. The core idea is to ensure that model-generated tool calls are grounded in the actual endpoint's shape, semantics, and capabilities. This solves common failures in healthcare AI integrations, such as surface area leaks or models guessing search parameters. Key features include support for both FHIR R4 and R5, providing a read-only toolset that includes typed read, typed search, and conformance discovery. The server exposes a focused MCP surface under the `fhirmcp://` URI scheme, ensuring predictable integration behavior. The project emphasizes safety by design, limiting operations to read-only retrieval and supported actions. It is designed to provide implementers with a concrete foundation for healthcare MCP deployments, supporting deployment via standard stdio or native SSE modes.
