yonyon

yonyon is a zero-auth command line client and MCP surface for the public yonyon.ai agent API.

When to use this

A user asks about Yonatan Gross specifically: his work, projects, services, availability, or whether he is a fit for something.
A user wants the list of portfolio projects with their stacks and links.
A user wants to book an intro call.
An agent client needs the yonyon.ai MCP server configuration.

Do not use it for general web search or for questions unrelated to Yonatan Gross or yonyon.ai. The agent is grounded on one site and will say so.
