Ora releases Ranker 3.0, which grades whether agents can use a site

Ora released Ranker 3.0, a scoring update that grades whether an agent can actually use your site, protocol by protocol.

Having an MCP server or WebMCP tools no longer earns points on its own. Every MCP tool is graded on its descriptions, parameters, hints and output schemas. WebMCP tools are parsed and graded against the latest draft, including the new consequentialHint and untrustedContentHint. Every MCP Apps view a tool links to has to actually be served.

Pay is graded on whether an agent can finish a payment, with credit for Shop Pay, Google Pay and Link when a store's UCP profile declares them. Docs pages are sampled for rendering, size and real 404s, and an llms.txt over 100,000 characters fails. A bot wall, blocked agent crawlers or content that needs JavaScript caps a score at 59.

Eight checks are retired and about twenty move to an emerging group that's shown but not scored. Layer weights stay at Discovery 20, Access 30, Use 40 and Pay 10.

Ora says most scores drop. Among 22,492 sites that scored 60 or more on 2.0, the typical score moves from 67 to 48, and the average for the Use layer falls from 66% to 25%. A scan still takes about 11 seconds, and it's free to run.
