The Cascade Protocol is a developer-first framework for building secure, interoperable health and wellness applications where patients own and control their data.
Build health apps with the full stack already handled.
TypeScript, Python, and Swift SDKs. CLI tools. Local-first encryption. FHIR import out of the box.
Get startedGive your agent structured, provenance-tracked health data.
Local MCP server. Consent-gated. Zero data egress. Semantic graph, not flat documents.
Agent integrationStructured health data with complete, reproducible provenance.
RDF knowledge graphs. SPARQL-ready. Full data lineage across every record.
Explore the vocabulariesBuilt for the future of health data: secure, portable, and truly owned by patients.
Health records stored in personal Solid Pods with WebID-based access control. Patients decide who sees their data and for how long — no cloud lock-in.
A three-layer architecture maps established clinical standards (FHIR, SNOMED CT, LOINC) through domain-specific vocabularies to patient-friendly summaries — so your data speaks every language.
AES-256-GCM encryption for all stored data. Keys live in the device keychain, never transmitted. No backend services required for core functionality.
Structured semantic data and a local MCP server let AI agents securely query health records with explicit user consent, comprehensive audit trails, and zero data egress.
TypeScript, Python, and Swift SDKs abstract the complexity of encryption, compliance, and semantic data modeling. Ship faster without reinventing health data infrastructure.
HIPAA-ready architecture with built-in audit logging, consent management, and data provenance tracking using W3C PROV-O. Privacy-first from day one.
The Cascade Protocol creates a secure, portable health record that follows patients across apps and providers.
Apps built on Cascade capture health data from device sensors, manual entry, HealthKit, or FHIR-compatible EHR imports.
Data is serialized to RDF/Turtle, encrypted, and stored locally in a Solid-compatible personal data pod owned entirely by the patient.
Patients grant granular, time-limited access to healthcare providers, researchers, or AI agents. All access is logged.
Linked Data format lets any compliant system read and process the data. No proprietary lock-in, no migration required.
The Cascade Protocol layers Cascade-specific vocabulary on top of proven W3C and healthcare standards — never replacing them.
Decentralized data pods with WebID authentication
W3C semantic web standards for linked data
W3C provenance ontology for audit trails
HL7 healthcare interoperability standard
Clinical terminology mapping
Laboratory observation identifiers
See the protocol in action with real-world health applications.
The first application built entirely on the Cascade Protocol. POTS Check is an at-home screening tool for Postural Orthostatic Tachycardia Syndrome (POTS) using Apple Watch heart rate monitoring and the NASA Lean Test protocol.
All test results are stored locally in an encrypted personal data pod, giving users complete ownership of their health screening history. Available on iPhone and Apple Watch.
