Whose server it is

Registry nameai.physea/liminalityverified in the MCP registry

The registry name sits under physea.ai. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-13 the server answered and asked for a sign-in with a Physea Labs account (OAuth). It shows its tool list only to signed-in users, so we list none here.

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "liminality": {
      "type": "http",
      "url": "https://liminality.physea.ai/mcp"
    }
  }
}

The first time it connects, the client opens a Physea Labs sign-in.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
