Frequently asked questions
EIS Group scores F on Supergood's API Report Card. EIS markets OneSuite as API-first with 9,000+ open APIs, but there is no public developer portal, sandbox, or API reference to verify any of it. Access comes only under commercial agreement as a carrier customer or contracted systems integrator, with docs delivered via the customer portal.
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.
Yes, via a managed API layer. Supergood builds REST APIs and MCP servers for authenticated enterprise web apps, so AI agents and internal tools can read and write data programmatically. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
Not that we could find. As of August 2026 there is no official EIS Group 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. EIS Group 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.
