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. Wassette leverages Rust without any run-time dependencies and aims to work with any AI agent supporting the Model Context Protocol (MCP).
