What happened
Cloudflare announced (Sept 2, 2026) support for running Cursor Cloud Agents' terminal, filesystem, and browser tool calls inside customer-controlled Cloudflare Sandboxes via a customer-operated worker maintaining outbound-only HTTPS to Cursor, keeping repositories/build caches/secrets on customer infrastructure (though inference file chunks and dashboard artifacts are uploaded).
Why it matters
Gives enterprises a way to run AI coding agents in a self-hosted sandbox with clearer network/data boundaries, addressing supply-chain and secret-exposure concerns around agentic coding tools.
Applicability
DevSecOps teams enabling AI coding agents for sensitive repos should adopt sandboxed execution and review inference/artifact data flows before scaling usage.
