**What we look for.** Whether your MCP server is listed in the official MCP Registry, matched to your domain.

**Why it matters.** Hosts and directories read the registry to find servers. Not listed means not found that way.

**How to pass.** Publish your server to the official MCP Registry with your domain's namespace.

Run it: `npx backwatch your-site.com --pillar presence` and find `mcp-registry-listed` in the report.
