agentshield vs ephemora-cell

agentshield: AgentShield is an offline, high-performance Rust security engine designed to detect risky behaviors in AI agent extensions and MCP servers before deployment. It identifies vulnerabilities like command injection, credential exfiltration, and prompt injection across various AI frameworks.; ephemora-cell: Ephemora Cell is an execution layer designed for running untrusted AI-generated code safely within a capability-based WASM environment. It provides strict resource limits and enforces security boundaries to protect the host system from potentially malicious or buggy code.
