Frequently asked questions
UnitedHealthcare scores D+ on Supergood's API Report Card. Partial, UHC has a real, free provider API program, but it is consultant-gated and not self-serve.
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.

The legacy "Link" self-service apps were retired at the end of 2021 and replaced by the current UnitedHealthcare Provider Portal with One Healthcare ID sign-on, Primary Access Administrators and formal third-party (RCM) access (https://www.hbma.org/news/commercial-payor-news/insurance-company-news/united/n_october-unitedhealthcare-news-managing-information-in-the-portal-just-got-simpler).

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. There is no official UnitedHealthcare 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. UnitedHealthcare 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.
