Microsoft Announces Open-Source "Wassette" Using Rust + WebAssembly To Help AI Agents
Microsoft formally announced today its newest open-source project: Wassette. The Wassette is MIT-licensed and includes Linux and macOS support alongside Windows while being a Rust+WebAssembly-based project focused on securing AI agents.
Microsoft's Wassette is built atop the Wasmtime run-time and allows for AI agents to autonomously fetch WebAssembly components from Open Container Initiative (OCI) registries and to be able to execute them. Via the WebAssembly runtime, Microsoft aims to have Wassette as secure as browser sandboxing. Plus Wassette provides additional safety control options on a deny-by-default basis.
Wassette leverages Rust without any run-time dependencies and aims to work with any AI agent supporting the Model Context Protocol (MCP). Wassette so far has conveniently install/setup guides for use with GitHub Copilot within VS Code, Claude Code, Cursor, and the Gemini CLI. There are also code examples spanning Python, JavaScript, Rust, and Go.
