What is holding Costco back
- MCP server, 8 points lost. No MCP server, server card or registry entry was found for this organization. Fix: Publish a remote MCP server with OAuth. Start with read only tools such as account status, orders or location search, and publish a server card at /.well known/mcp/server card.
- Developer and data sharing program, 4 points lost. No developer portal or data sharing program was found on public pages. Fix: Document the program, the standard in use for example FDX in US banking, the supported partners and a sandbox.
- Passkeys at sign in, 4 points lost. No passkey signal was found on the sign in page or in the published pages read. A prompt that starts only after a person types is not visible to the scan. Fix: Offer passkeys with conditional UI on the sign in page and for step up approvals.
- Documented delegate and data sharing controls, 4 points lost. No public page on delegate access or connected app controls was found. Fix: Publish a help page on delegate access and add a connected apps screen where customers revoke access.
What already works
- OAuth and OpenID metadata
- PKCE and client registration
- Content available without running scripts
