What is FossibleWorks Health Central?

Health Central is one open-source healthcare platform that brings your clinical data and your operations together in a single, real-time context — a FHIR-native clinical record and a full operations and revenue-cycle backbone working as one system instead of an integration project that never ends. It's designed from day one for AI agents and autonomous AI workers to operate safely on top of it.

What's the difference between AI agents and AI workers?

AI agents assist — copilots that work alongside clinicians and staff, drafting notes, summarizing history, surfacing context, and recommending next steps while a human stays in control. AI workers get work done autonomously — owning end-to-end operational workflows like revenue cycle (claims, prior auth, denials, payment posting, eligibility), patient operations, care coordination, and back office. Both run through the same permissions, workflows, and audit trail as human staff, which is what makes them safe in front of real clinical operations.

What makes Health Central the right foundation for healthcare AI?

Four properties, on both the clinical and operational sides: everything is programmable and exposed to agents as scoped tools; the clinical record is FHIR-native by construction, a standard modern AI already understands; agents are governed by the same permission framework as humans with a complete audit trail, so 'can suggest, but not act' is a first-class pattern; and it's interoperable out of the box. And it all runs in real time, so agents and workers act on current data, not last night's batch.

Who is Health Central for?

Greenfield digital health companies that want standards-native, AI-ready, fully owned infrastructure from day one — no legacy migration, no 'we'll add FHIR later.' And AI healthtech companies that want to ship their agent or AI worker, not the infrastructure beneath it, on a real, auditable clinical-and-operational system of record. It's open source top to bottom, so you own the code, the data, and the roadmap, with no per-seat licensing and no vendor lock-in.

The AI-native foundation for the healthcare product you're building

If you're building a digital health company — or an AI product for healthcare — the hard part was never your idea. It's the foundation underneath it: a clinical record that's actually standards-compliant, an operations and billing backbone that actually runs a business, and the two of them working as one system instead of an integration project that never ends.

Health Central is that foundation. One open-source platform that brings your clinical data and your operations together in a single, real-time context, designed from day one for AI agents and autonomous AI workers to operate safely on top of it.

Build your product. Not your plumbing.

The foundation problem every healthtech builder hits

In a typical build, clinical data lives in one system and operations and billing live in another. Keeping them in agreement becomes a permanent tax. Patient-facing apps, clinician tools, and billing workflows each speak a different dialect. And the moment you try to add AI, you discover the real wall: an agent can only act on what it can see, and your data is split across systems that were never meant to be reasoned over as a whole.

This is where most healthcare AI prototypes stall. Not because the model is weak — because the foundation is.

Health Central removes the seam before you ever hit it.

One context for clinical and operations

This is the difference that changes what you can build.

Patients, encounters, orders, lab and imaging results, prescriptions, claims, scheduling, inventory, revenue cycle — your clinical record and your operational backbone live in one foundation, in real time. The clinical side runs on Medplum, FHIR-native and standards-compliant as data is created, not converted to a standard later. The operational side runs on Frappe and ERPNext — a mature, battle-tested ERP and practice-management engine running a real business at scale across thousands of organizations.

Because both halves are one platform, the most valuable healthcare workflows — the ones that are both clinical and operational — become native instead of impossible. An AI worker resolving a denied claim can see the diagnosis codes, the encounter, the invoice, and the approval workflow at the same time, because they aren't in four systems. They're in one.

That's a workflow that's structurally hard to build on legacy EHRs, where clinical and operational data live in separate stacks behind separate APIs. On Health Central, it's the default.

Built for two kinds of AI

Healthcare AI isn't one thing. Health Central is built for both.

AI agents that assist

Copilots that work alongside your clinicians and staff — drafting clinical notes, summarizing a patient's history, surfacing the right context at the right moment, recommending an order or a next step. The human stays in control of the final action. The agent makes them faster and sharper.

AI workers that get work done

Autonomous workers that own end-to-end operational workflows:

Revenue cycle — claims preparation and submission, prior authorization, denial management, payment posting, eligibility checks
Patient operations — intake and registration, scheduling and rescheduling, reminders, follow-up
Care coordination — routing results, flagging gaps, triggering the next step in a care plan
Back office — inventory, procurement, reconciliation, reporting

These aren't chatbots bolted onto a dashboard. They're operators inside your system — working through the same permissions, the same workflows, and the same audit trail as your human staff. That's what makes them safe to put in front of real clinical operations, and it's why RCM and operational automation are some of the best things you can build on this platform.

Why it's the right foundation for healthcare AI

Four properties make the difference between an AI demo and AI you can actually deploy. It's the same infrastructure-first principle Medplum lays out in its own guide to healthcare AI — and Health Central was built with all four, extended across both the clinical and operational sides.

Everything is programmable, and everything is an agent tool. Every clinical resource and every operational record is reachable through a complete API — and exposed to agents as discoverable, scoped tools through the Model Context Protocol (MCP). There's no "integration phase," no custom tool layer to write. Agents and developers operate on the same system, through the same controls. See how our AI layer works →

FHIR-native by construction. Your clinical record is built on FHIR R4 — the global standard modern language models already understand. Agents reason over clinical data without brittle, custom schemas, and what they write maps cleanly into validated, reusable resources.

Guardrails that make agents safe to ship. Every agent is governed by the same permission framework as a human user. You decide what an agent can read, suggest, or do — and can suggest, but not act is a first-class pattern. Every action an agent takes is captured in a complete, standards-based audit trail, so what your AI did is always verifiable. This is the part that turns "interesting prototype" into "production-grade and compliant."

Interoperable out of the box. Labs, medications, imaging, terminology (ICD-10, SNOMED-CT, LOINC), SMART on FHIR apps, HL7, patient portals — native, not retrofitted. Your agents participate in the whole healthcare ecosystem, not an island.

And it all runs in real time — agents and workers act on current data, not last night's batch.

Built on a proven open-source stack — with the hard part already solved

Health Central isn't a proprietary black box and it isn't a pile of parts you assemble yourself. It's three of the most proven open-source platforms in healthcare and operations, integrated into one real-time, AI-ready foundation — so you get battle-tested components and the integration that's normally the year-long project.

Frappe & ERPNext power the operational and revenue-cycle backbone — practice management, billing and RCM, inventory, accounting, HR, and a low-code layer to build anything specific to your model. Proven across 10,000+ organizations in 140+ countries. → Fossible HIS
Medplum powers the FHIR-native clinical record — the standards-compliant system of record, patient and provider apps, terminology, and the SMART on FHIR app ecosystem. → Medplum Health Data Platform
Tuva powers AI-ready analytics — standardized clinical data flows into a purpose-built clinical data warehouse for population health, risk stratification, outcomes, and operational forecasting.

What you don't have to build is the part that matters most: getting clinical, operational, and analytical data to work as one coherent, real-time, agent-addressable foundation. That's what Health Central is.

Around these sit the ecosystems they bring with them — CRM for patient acquisition, helpdesk, and back office on the operations side; third-party SMART on FHIR apps and clinical integrations on the clinical side, each safely scoped to exactly the data it's authorized for, all under one identity and one audit trail.

You own the code, the data, and the roadmap. No per-seat licensing. No vendor that can revoke your access, raise your price, or sunset a feature you depend on. Host it anywhere — cloud, on-prem, hybrid.

And because it's all open standards and open source, AI tools already understand it — which means building your agents and workers on top is faster and more reliable from the first line.

Who Health Central is for

Greenfield digital health startups. Start on standards-native, AI-ready, fully owned infrastructure from day one. No legacy migration, no technical debt, no "we'll add FHIR later." The foundation that would take you a year and a team to assemble is your starting line.

Multi-site hospitals with ERP needs. Run clinical care and the full operational and financial backbone — billing, inventory, procurement, accounting, HR — across every location on one platform, instead of bolting an EHR onto a separate ERP.

Specialty providers, starting focused. We tailor the Medplum EMR/EHR for one or two specializations to start with, so you go live on workflows built for your discipline — then expand as you grow.

Everyone benefits from the AI-native surface. Whichever you are, the same agent- and worker-ready foundation comes with it — AI that assists your staff and autonomous workers that get operational work done, governed and auditable from day one.
