V8 Sandbox
The V8 sandbox is an isolated execution environment provided by Google's V8 JavaScript engine. By restricting memory access, system calls and network capabilities, it constrains untrusted code within a least-privilege boundary.

The V8 sandbox is an isolated execution environment provided by Google's V8 JavaScript engine that constrains untrusted code within a least-privilege boundary by restricting memory access, system calls and network capabilities.
In the AI connector scenario, each tool call runs in a separate V8 isolated instance, so even if the agent is induced by a malicious prompt to perform an unauthorized operation, its impact is confined within the sandbox and cannot reach the host file system or sensitive data.
DLP monitors and blocks the exfiltration of sensitive data, and SSRF protection prevents the agent from being induced to make unexpected requests to the internal network; these three (the V8 sandbox, DLP and SSRF protection) together constitute the governance layer.
In the MCPFusion architecture, each connector runs in an isolated V8 sandbox to prevent side effects or malicious escape attempts.
