Cloudflare adds support for Cursor Cloud Agents on Cloudflare Sandboxes

Cloudflare has announced support for running Cursor Cloud Agents on Cloudflare Sandboxes, giving developers and enterprise platform teams a way to run AI coding agents in isolated, customer-controlled environments.

The integration allows Cursor's self-hosted machines workflow to execute inside a sandbox environment sitting within the customer's own Cloudflare account.

Cursor continues to handle the agent loop - inference, planning and orchestration - while tool calls, including terminal, filesystem and browser actions, run inside the customer-controlled sandbox rather than on shared or vendor-managed infrastructure.

Cursor Cloud Agents use an outbound connectivity model: a Cursor worker runs the Cursor CLI and opens a long-lived outbound HTTPS connection to Cursor's backend, where agent tool calls are sent over that connection. Cloudflare said inbound connections into the customer's network are not required.

For teams running Cursor Self-Hosted Machines, the integration supports both individual and enterprise configurations. Individual developers can connect a single worker through My Machines, while enterprise teams can use Cursor self-hosted worker pools as named routing targets, allowing agent chats to queue until an available worker claims them.

Pool orchestration lets teams watch demand, spin up capacity when needed and release it when sessions end.

During self-hosted operation, repositories, build caches and secrets remain on the customer's machines. File chunks read during inference, along with Cloud Agent artefacts such as screenshots, videos and log references, are uploaded so they can appear in pull requests and dashboards.

Teams can also use the Cloud Agents API to integrate self-hosted machine status or pool routing into their own systems.

"Developers want powerful AI tools that fit naturally into their workflows, and enterprises need those tools to run in environments they control,” said Dane Knecht, chief technology officer at Cloudflare.

"Cloudflare Sandboxes gives teams the freedom to use the AI tools they prefer while giving organisations a secure, isolated place to run agent work."

Bringing Cursor Cloud Agents to Cloudflare Sandboxes is another step toward making Cloudflare the execution layer for the next generation of agentic applications.” 

The announcement extends Cloudflare's existing integrations with Devin Outposts and Claude Managed Agents.
