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.
Factorial has partial MCP support. Factorial has not published an official MCP server, but small community servers exist, including one covering employee directory and org structure data. Both are low-activity projects with 2026 commits and there is no vendor documentation or registry listing.
Partially. MCP support for Factorial exists but is incomplete, so what MCP clients like Claude, Cursor, and Codex can reach depends on what the available server covers.
