What is holding Del Taco 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. OAuth and OpenID metadata, 5 points lost. No OAuth or OpenID metadata was found on the 1 hosts that answered. 12 other hosts did not answer the scanner and could not be checked. Agents cannot discover where to send a customer to approve access. Fix: Publish /.well known/oauth authorization server and /.well known/oauth protected resource for the customer facing APIs.
  3. 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.
  4. PKCE and client registration, 4 points lost. No authorization server metadata, so PKCE and client registration could not be confirmed. Fix: Require PKCE with S256 and support client ID metadata documents or dynamic client registration for approved agent clients.

What already works

  • Robots policy for user triggered agents
