## What is holding T Mobile back

1. **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.
2. **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.
3. **PKCE and client registration**, 4 points lost. Neither PKCE nor a registration path is published. Fix: Require PKCE with S256 and support client ID metadata documents or dynamic client registration for approved agent clients.
4. **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
- Passkeys at sign in
- Content available without running scripts
