Or add to your MCP client config:

{
  "mcpServers": {
    "fortress": {
      "command": "uvx",
      "args": [
        "tilion"
      ],
      "env": {
        "TILION_MCP_PREWARM": "<YOUR_VALUE>",
        "TILION_MCP_HEADLESS": "<YOUR_VALUE>",
        "TILION_ALLOW_PRIVATE_EGRESS": "<YOUR_VALUE>",
        "TILION_BASE_URL": "<YOUR_VALUE>",
        "TILION_API_KEY": "<YOUR_VALUE>"
      }
    }
  }
}

TILION_MCP_PREWARM — Boot the browser at startup so the first tool call is instant (default 1).
TILION_MCP_HEADLESS — Set 0 to show a visible browser window (default 1).
TILION_ALLOW_PRIVATE_EGRESS — Set 1 to allow tools to reach localhost / private IPs (SSRF guard off).
TILION_BASE_URL — Run browsers on a hosted Tilion server instead of locally.
TILION_API_KEY secret — Bearer key for the hosted Tilion server (cloud mode only).

This server takes extra arguments — see its repository.
