On this episode, we learned about Wassete, A security-oriented runtime that runs WebAssembly Components via MCP.
Wassette is a secure, open-source Model Context Protocol (MCP) server that leverages WebAssembly (Wasm) to provide a trusted execution environment for untrusted tools. MCP is a standard how LLMs access and share data with external tools. By embedding a WebAssembly runtime and applying fine-grained security policies, Wassette enables safe execution of third-party MCP tools without compromising the host system.
Why Wassette?
Convenience: Wassette makes it easy to extend AI agents with new tools, all without ever having to leave the chat window.
Reusability: Wasm Components are generic and reusable; there is nothing MCP-specific about them.
Security: Wassette is built on the Wasmtime security sandbox, providing browser-grade isolation of tools.
