The Model Context Protocol (MCP) standardizes context retrieval and tool execution, but granting LLMs access to dynamic execution environments introduces critical runtime vulnerabilities. Traditional containerization (e.g., Docker/containerd) introduces unacceptable latency overhead for sub-second agentic loops, while static IAM/RBAC models fundamentally fail to constrain non-deterministic generated code.

This technical session details the architectural implementation of embedding a WebAssembly (WASM) runtime within an MCP server to enforce a strict, capability-based execution boundary. We will deconstruct how to compile MCP tools to WASM modules and utilize the WebAssembly System Interface (WASI) to ensure that any logic invoked by an LLM is isolated from the host operating system.
