GBox MCP Server — agentic threat model

Not certain from the listing — GBox is an MCP server providing execution environments rather than hosting its own foundation models. The primary L1 threat is that an external model driving GBox could be manipulated via prompt injection to execute malicious payloads inside the sandbox.

Not certain from the listing — GBox focuses on session-scoped execution environments rather than managing large-scale RAG or vector databases. The primary data risk is the potential exfiltration of sensitive session data or environment variables during execution.

GBox directly exposes powerful tools (terminal, browser, Android/desktop automation) to the agent framework. The primary threat is tool misuse, where an agent is manipulated into running destructive commands or performing unauthorized GUI actions within the active session.

This is GBox's primary layer. It acts as an isolation boundary (sandbox) to prevent host compromise. Threats include container escape vulnerabilities, lateral movement from the sandbox to other local network resources, and resource exhaustion on the host.

Not certain from the listing — The description does not detail built-in logging, auditing, or guardrails for the commands executed inside the sandbox. Insufficient logging of terminal commands and GUI interactions represents a major observability gap.

As a self-hostable tool, security and compliance rely heavily on the user's deployment configuration. Key threats include weak authentication to the MCP server and a lack of fine-grained authorization policies governing which agent can access which sandbox.

In a multi-agent ecosystem, a compromised or malicious agent could leverage GBox's browser or desktop automation capabilities to interact with other local applications, leading to cascading failures or unauthorized cross-application actions.
