Claude Code

claude mcp add --transport http 404-directory https://404.directory/mcp

Claude, ChatGPT, Cursor and other apps

Add it as a custom connector with this URL (Streamable HTTP):

https://404.directory/mcp

This server expects extra headers, usually an API key from its maker.

Or run it locally (npm)

claude mcp add 404-directory -- npx -y @mmvv1638/404-directory-mcp@0.10.3

Cursor, VS Code and other apps (mcp.json)

{
  "mcpServers": {
    "404-directory": {
      "url": "https://404.directory/mcp"
    }
  }
}
