Ora's one-line summary: Turns agents away at the door: the homepage is blocked by a WAF challenge, and there is no OpenAPI spec, OAuth or MCP server.

What an assistant meets at the door

Before an assistant can read, compare or buy, it has to get in. These rows are the door: whether the bot shield lets the main agents through, what robots.txt tells the search, training and user-triggered agents, and whether the home page has text without running JavaScript.

What it can read, and what it can do

The reading layer is what an assistant takes away from the pages: a text file written for it, markdown on request, structured data about the company, a sitemap. The act layer is whether it can do anything through a published interface rather than by clicking through the site.

Three fixes to hand to the web team

Ora estimates how many points each open check would return. These are the largest on this read, in Ora's words where it gave them, so a leader can hand the list over without translating it.

  1. OpenAPI spec published, worth about 4.9 points by Ora's estimate: No OpenAPI/Swagger specification found.
  2. MCP server / manifest, worth about 4.6 points by Ora's estimate: No MCP server or manifest found.
  3. Developer portal, worth about 4.2 points by Ora's estimate: No developer portal found.

Our read

Marathon Petroleum challenges every agent and leaves one endpoint and one search result behind the wall. Bot management challenged ChatGPT-User, OAI-SearchBot, Claude-User and PerplexityBot, robots.txt answered with a 403 challenge and the home page came back as a security page, so the door, content, policy, structured-data and metadata rows are unverified rather than failed, and the Access layer reads 1 of 48; there is no sitemap and no llms.txt. What Ora could reach is a GraphQL endpoint at marathonpetroleum.com/graphql with introspection gated, and a search that placed api.developer.marathonpetroleum.com tenth for the API documentation, a host the scan did not find from the site; there is no OpenAPI specification, and neither an MCP server nor OAuth discovery, so the Usability layer reads 12 of 58. The Discovery layer is 8 of 10, with the Wikidata item confirmed and the domain fifth for its own name. A refiner has little reason to serve agents and every reason not to serve them a 403; the challenge is the row that moves this D.
