Joost Helfers portfolio bronze

“Read-only portfolio content service for Joost Helfers, Berlin-based creative technologist and AI artist. Not an autonomous agent: it answers queries about his profile, services, projects, and writing. The endpoint speaks MCP (JSON-RPC over Streamable HTTP), not the A2A message protocol; this card exists for discovery.
