**What we look for.** Whether each MCP server has a server card that says what it is and where to connect.

**Why it matters.** It lets an agent decide whether to connect before it opens a session.

**How to pass.** Publish a server card next to your server and list it in your discovery file.

This check needs a deep scan, which the hosted monitor will run.
