client:Claude Desktop transport:streamable-http resource:Endpoint Catalog

Add Alien Plugg x402 API to Claude Desktop

  1. 01

    Open ~/Library/Application Support/Claude/claude_desktop_config.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "alien-plugg-x402": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://base44.app/api/apps/6a5fdd57651262e86b24133e/functions/mcpHandshake"
      ]
    }
  }
}
  1. 02

    Save the file and restart Claude Desktop.

  2. 03

    Endpoint Catalog is surfaced in the attachment menu, where you pick it as context. It is context to attach, not an action to run.

  3. 04

    If it does not appear, check that Alien Plugg x402 API is connected and that you are looking at its resources rather than its tools.

Claude Desktop has no remote transport in its config file, so this bridges through mcp-remote. Restart the app after saving. Claude Desktop docs

Same resource, other clients

Read from the server itself, by connecting to it and calling resources/list on 24 September 2026. A listing does not declare its resources, so asking is the only way to know them, and this is what the server actually offers rather than what its listing claims. Names only are stored; connect the server for each resource's type and contents.
