# Nieuwsbrief woensdag 9 september 2026

Dagelijkse update over de AI-tools die we volgen. Koppen komen van publieke bronnen (X, GitHub, Hacker News); de Nederlandse duiding en samenvatting zijn machinaal geschreven. Elke kop leidt naar onze eigen nieuwspagina over dat onderwerp; de bronlink staat ernaast.

## In het kort

Meta introduceert Muse, een persoonlijke consumentenagent met Secure VM en Sentinel, voorlopig alleen in de VS. Check Point toont op Fal.Con hoe een ChatGPT-sandbox via een gedeelde JFrog Artifactory als cross-account clipboard werkte, waarna OpenAI de instance heeft uitgezet; CrowdStrike laat zien hoe Falcon Guardian een Claude Code-agent blokkeert die AWS-credentials lekte. DeepMind publiceert AlphaGenome Atlas, een voorspellende kaart van DNA-letterveranderingen. Verder: MCP Python SDK v2.2.0, n8n 2.39.0, en financieringen voor Antioch, Celero, Sapien en Fluencify.

## Achtergrond: wat er verder speelde

- Meta Muse (8 sept ~21:00 CEST): consumer personal agent met Secure VM + Sentinel. US-only (iOS/Android/web/WhatsApp). Free + $20 Power / $100 Maximum. Confidential VM (user-held keys) beloofd later dit jaar, niet live. UX-referentie tegen OpenClaw-klasse always-on — niet iets voor je Mini. ([3](https://about.fb.com/news/2026/09/introducing-muse-personal-ai-agent/))

- Check Point: ChatGPT-sandbox als cross-account clipboard (8 sept): containers geïsoleerd, maar gedeelde JFrog Artifactory liet account A een verborgen taak schrijven die account B’s sessie uitvoerde (PoC: Gmail via connected app). OpenAI heeft de Artifactory-instance decommissioned. Les: één writeable package-cache per untrusted agent. ([4](https://research.checkpoint.com/2026/the-shared-clipboard-inside-the-sandbox-cross-account-data-leakage-in-chatgpt/))

- DeepMind AlphaGenome Atlas (8 sept): ~1 PB predictive map van elke single-letter DNA-change + AVI-score. Free academic portal, API, en een skill in Google Antigravity. ([5](https://deepmind.google/blog/alphagenome-atlas-a-predictive-map-of-every-possible-dna-letter-change-in-the-human-genome/))

- Decart-vervolg (Globes): due diligence + eis om naar de VS te verhuizen zou de Anthropic-deal hebben gekild. Dit blijft secundair/gerucht naast Bloomberg’s walk-away van 8 sept — geen filing. ([6](https://en.globes.co.il/en/article-due-diligence-and-move-to-us-derailed-decart-acquisition-1001554805), [7](https://www.bloomberg.com/news/articles/2026-09-08/anthropic-said-to-walk-away-from-6-billion-decart-acquisition))

- MCP/SDK-nacht: AWS Labs MCP pin’t SDK ([8](https://github.com/awslabs/mcp/releases/tag/2026.09.20260908143235)); MCP Python v2.2.0 ([9](https://github.com/modelcontextprotocol/python-sdk/releases/tag/v2.2.0)); n8n 2.39.0 fixt Anthropic thinking-block parse ([10](https://github.com/n8n-io/n8n/releases)).

- Grok 4.7 nog niet shipped. Enige harde datum is nog Elons X-post van 2 sept (“in 10 days” ≈ 12 sept). Geen modelkaart. ([11](https://x.com/elonmusk/status/2094983639780204846))

- Cursor ↔ OpenAI-cutoff blijft 12 november. Astra komt nooit in Cursor; in OpenClaw via API/Codex sinds 2026.9.2. ([12](https://openai.com/index/our-decision-on-cursor-following-its-acquisition-by-spacex/), [13](https://cursor.com/changelog))
