SOVEREIGN AGENTS 2026 — The Sovereign AI Blitz Hackathon
🇫🇷 For the first time in Europe, private AI agents meet sovereign French State data. Build an autonomous AI agent that solves a REAL business problem — using the most advanced agentic stack of 2026 — in just 90 minutes.
This isn't a student hackathon. This is the arena.
🎯 The Challenge
From idea to functional prototype in 90 minutes flat. You pick the use case and you ship.
Mandatory Stack:
🔧 Google ADK (Agent Development Kit) — Multi-tool agent orchestration
🖥️ Antigravity IDE — Google's Agent-First IDE
⚡ Gemini CLI — Raw power, command-line speed
🏛️ National MCPs — Official DINUM servers (Data.gouv.fr, Taxation, Real Estate)
🇫🇷 Why "Sovereign"?
The French government has opened its data — DPE, land registry, taxation, public procurement — via MCP servers that your AI agents can query in real time. This hackathon is the first event ever to bridge private agents with sovereign State data. A European answer to closed US ecosystems.
