Report #68777

[frontier] Tool execution in agents creates security vulnerabilities and environment pollution

Sandbox all MCP tool execution using containerized environments \(E2B, Docker\) with ephemeral filesystems, ensuring agent tools run in isolated sandboxes with no host access

Journey Context:
Running agent tools directly on host systems or simple subprocesses creates security risks and state leakage between runs. By configuring MCP servers to execute in sandboxed containers \(using E2B's DevContainers or Docker-in-Docker\), each tool invocation gets a clean environment. This pattern treats agent tools as serverless functions with strict isolation, preventing prompt injection from leading to host compromise.
