## What is holding Y Combinator 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. **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.
4. **llms.txt guide for agents**, 3 points lost. No llms.txt file was found at the site root. Fix: Publish /llms.txt with links to product, pricing, support and location pages.

## What already works

- OAuth and OpenID metadata
