OncoEMR (Flatiron Health) API
No open API. A FHIR surface exists as a paid per-tenant add-on with docs behind a registration wall; Flatiron states FHIR APIs may require additional fees. Everything else runs through Flatiron-managed HL7 interfaces with an approved vendor list. No SDKs or public webhooks.
Frequently asked questions
OncoEMR (Flatiron Health) scores F on Supergood's API Report Card. No open API. A FHIR surface exists as a paid per-tenant add-on with docs behind a registration wall; Flatiron states FHIR APIs may require additional fees. Everything else runs through Flatiron-managed HL7 interfaces with an approved vendor list. No SDKs or public webhooks.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.

Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Not that we could find. As of August 2026 there is no official OncoEMR (Flatiron Health) MCP server in any public registry, and no maintained community server we're aware of. We re-verify this periodically — report an inaccuracy below if we missed one.
Not natively. OncoEMR (Flatiron Health) doesn't publish an MCP server, so MCP clients like Claude, Cursor, and Codex have nothing to connect to out of the box. If that changes, this page will reflect it.
