If you ever wondered what I'm doing with all my AI coding time, here's a sneak preview:
Voluntarix - a volunteer management system built with Spring Boot, Vaadin & jOOQ
An MVP will be available soon.

The jOOQ MCP server is live 🥳
If you use Claude Code, you can add it with this command:
claude mcp add --transport sse jOOQ jooq-mcp.fly.dev/sse
If you can't use SSE transport directly, you can use it with mcp remote.
