About:
Wassette is a security-focused runtime environment designed for executing WebAssembly (Wasm) components. It leverages the Model Context Protocol (MCP) to facilitate secure communication and integration between Wasm modules and external systems. This enables a sandboxed, verifiable, and portable execution model for modern distributed applications.
Key Features:
  • Secure sandboxing for WebAssembly components
  • Integration via Model Context Protocol (MCP)
  • Portable runtime for distributed systems
  • Security-oriented design principles
Use Cases:
  • Executing untrusted code in a secure sandbox
  • Building modular, secure microservices
  • Integrating WebAssembly modules into existing systems
Alternatives:
  • Wasmtime – A general-purpose Wasm runtime, while Wassette specifically focuses on security and MCP integration.
  • Node.js – A JavaScript runtime; Wassette targets Wasm components for enhanced security and portability.
