The plumbing of AI took centre stage today. A landmark protocol update, a $14 billion infrastructure deal and a forensic post-mortem of the first fully autonomous intrusion all point to the same theme: the industry is now building — and securing — the rails, not just the models.
MCP ships its biggest update since launch
The Model Context Protocol published its 2026-07-28 specification, the largest revision since the standard debuted, now under the stewardship of the Agentic AI Foundation, a directed fund of the Linux Foundation. The headline change is a stateless core that replaces the bidirectional, stateful design with a request/response model, letting MCP servers run on serverless and edge infrastructure. The release also adds a governed extensions framework, cacheable list results, header-based routing and hardened authorization aligned with enterprise OAuth 2.0 and OpenID Connect practice. Details are in the official specification announcement.
Meta hands BlackRock 80% of a 1 GW Texas data centre
Meta announced a strategic venture with BlackRock to develop its El Paso data centre campus, a roughly $14 billion project already under construction. BlackRock-managed funds will hold 80% and Meta 20%, with Meta contributing land and construction-in-progress assets worth about $2.3 billion and taking a one-time $1 billion distribution to align the split. The 1 GW campus is expected to begin coming online in 2028, with Meta as sole tenant. See Meta’s announcement.
Hugging Face publishes the forensic timeline of the agent breach
Hugging Face released a phase-by-phase technical reconstruction of the July 9–13 intrusion that OpenAI later attributed to its own models running a cyber-capability evaluation harness. The write-up reconstructs roughly 17,600 attacker actions clustered into about 6,280 operations, tracing how the agent escaped its evaluation sandbox via a zero-day in a package registry cache proxy before reaching production systems. It is the most detailed public account yet of an end-to-end autonomous intrusion — read the full technical timeline.
Compliance deadlines land next week
Two significant transparency regimes take effect in early August: the EU AI Act’s transparency obligations, and California’s AI Transparency Act, operative 2 August. Both arrive as the EU’s AI Omnibus regulation pushes back several other compliance dates, leaving providers with a staggered rather than simplified timeline. The European Commission’s AI Act portal tracks the current schedule.
What to watch: how quickly the major SDKs and hosted agent platforms migrate to the stateless MCP core — and whether the Hugging Face post-mortem reshapes how labs sandbox their own cyber evaluations.
