Anthropic's own telemetry says users approve roughly 93% of Claude Code's permission prompts without real scrutiny. Two 2026 engineering posts, a sandboxing feature, and an SDK callback show what they built instead of asking harder — and it's not a smarter warning dialog.

Anthropic's Aug 27 research preview of MHS gives AI agents a standard interface to operate lab and manufacturing hardware. As a Tech Lead who has wired MCP servers to internal tools, here's why this is MCP's shape applied to physical devices — and what breaks when the tool call controls a centrifuge instead of a database.
