Sandboxing

← Previous Chapter: Part 2: Hierarchical Memory | Series Hub | Next Chapter: Part 4: AgentOps & Observability → Answer-first: Standardizing agent tools on the Model Context Protocol (MCP) provides type-safe JSON-RPC contracts, token-budget enforcement, and secure capability boundaries. Code execution tools must run inside isolated WebAssembly (WASI 0.2) or micro-VM sandboxes.

Answer-first: Securing enterprise MCP deployments requires an uncompromising defense-in-depth model that replaces naive regex filtering with AST parameter sanitization, kernel-isolated sandboxing via gVisor, and real-time DLP tokenization. Implementing continuous behavioral authorization and egress network policies neutralizes indirect prompt injection, tool poisoning, and SSRF attacks, guaranteeing that untrusted model completions cannot execute arbitrary code or exfiltrate sensitive corporate data. ← Part 4: MCP Gateway Architecture | Next Chapter: Part 6: Observability & Audit Trail → ...
