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 Keap 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. Keap 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.
