Microsandbox MCP — agentic threat model
Microsandbox MCP acts as a secure execution layer for untrusted AI-generated code, reducing host-level risks but presenting a high-impact target if its isolation boundaries are breached during arbitrary code execution.

Scored with the canonical OWASP AIVSS formula (AIVSS calculator reference); agentic risk factors estimated from the agent’s described capabilities.
MAESTRO 7-layer threat model
Per-layer threats for this agent. Layers tagged “not certain from listing” are general, caveated commentary where the public description didn’t pin that layer.
Not certain from the listing — The platform is model-agnostic and acts as an execution target for external LLMs; threats include adversarial code generation designed to exploit the sandbox runtime.
Not certain from the listing — The agent handles data analysis workloads, but specific data storage, vector databases, or RAG pipeline integrations are not detailed in the directory listing.
The platform exposes Model Context Protocol (MCP) tools to orchestrate code execution and browser-use workloads, making it vulnerable to tool misuse and prompt injection that triggers malicious code generation.
This is the core focus of the agent. It provides a self-hosted sandbox to isolate untrusted code execution and browser-use from the host, mitigating container escape, host compromise, and lateral movement risks.
Not certain from the listing — The directory listing does not specify what logging, execution auditing, or runtime guardrails are active inside or outside the sandbox environment.
The agent is designed as a security control (sandboxing) to reduce code-execution risk, but the listing does not detail authentication, authorization policies, or compliance certifications.
Supports browser-use and MCP tool integration, exposing the sandbox to external web environments and potential multi-agent orchestration vulnerabilities if untrusted agents interact with the runtime.
