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.
Workday has partial MCP support. Workday does not publish an official MCP server. Third-party community servers exist, including a read-only connector maintained by CData, but none are vendor endorsed.
Partially. MCP support for Workday exists but is incomplete, so what MCP clients like Claude, Cursor, and Codex can reach depends on what the available server covers.
