This is the right problem to solve. At Arcade, we see the same gap — agents get shell access, API keys, and network by default. The permissions model is backwards.
sandbox-profiles is a solid primitive for local agents. The missing piece in production is the tool layer — even a sandboxed agent can still make dangerous API calls if the MCP tools it has access to aren't individually authed and scoped.
The real stack is: sandbox the runtime (what Agent Safehouse does) + scope the tools (what we do with JIT OAuth at the MCP layer). Neither alone is enough.

Nice work shipping this.
