wassette

Why we included this project

Giving an agent a new capability usually means trusting it with more commands. Wassette takes a different route: tools are WebAssembly components served over the Model Context Protocol, and each one runs inside the Wasmtime sandbox, so a coding assistant like Claude Code or Copilot CLI can pick up a capability on demand without ever escaping that boundary. Components ship as packaged, permissioned units with their own access rules, which keeps the model limited to what the tool exposes rather than the whole machine. Since they're distributed as ordinary OCI artifacts, versioning and reuse follow the same habits teams already have for containers. The README is upfront that this is early development, so think of it as a promising prototype for tool delivery and a live test bed for the security model, not something to run in front of production agent fleets yet.
