Claude, ChatGPT, Cursor and other apps

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

https://0n3.app/mcp

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

Or run it locally (npm)

claude mcp add 0nmcp -- npx -y 0nmcp@5.0.6

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

{
  "mcpServers": {
    "0nmcp": {
      "url": "https://0n3.app/mcp"
    }
  }
