- Introduction of Wassette, a security-oriented runtime for WebAssembly Components via Model Context Protocol (MCP).
- Wassette allows autonomous fetching and execution of Wasm Components from OCI registries with secure sandboxing.
- Features include a fine-grained, deny-by-default permission system for enhanced security.
- Wassette bridges Wasm Components and MCP, interpreting library interfaces and exposing them as MCP tools.
- Written in Rust, Wassette is a standalone binary with zero runtime dependencies.
- Demonstration of setting up Wassette with GitHub Copilot in VS Code.
- Example of loading and running a basic Wasm Component (time server) in GitHub Copilot.
- Explanation of Wassette's security model using Wasmtime's sandbox for least privilege access.
- Example of loading a network-enabled Wasm Component (fetch) and managing permissions.
- Future directions include hosting Wasm Components over the network and tools for easier porting.
- Encouragement to explore Wassette on GitHub, with resources for various languages and platforms.
