Connect your AI
Let your AI sign you in.
Promptoscope is also a tiny MCP server, the open standard assistants use to call outside tools. Add it once, then just ask your assistant “what’s my AI star sign?” It reviews what it knows about you, scores you, and calls the mechanism itself. Nothing is stored on our side.
