before you install - you'll need

The README does not document required environment variables for a basic install.

Claude Code

claude mcp add blackwell-systems-knowing -- npx -y @blackwell-systems/knowing

{
  "mcpServers": {
    "blackwell-systems-knowing": {
      "command": "npx",
      "args": [
        "-y",
        "@blackwell-systems/knowing"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.
