- **Host** — The chat client (e.g., Claude Desktop) that connects to servers, embeds Views in iframes, and proxies communication between them.
- **View** — The UI running inside a sandboxed iframe. It receives tool data from the Host and can call server tools or send messages back to the chat.
The View's `App` subclasses the base MCP SDK `Client`. The Host's `AppBridge`
subclasses the base MCP SDK `Server` for the inner iframe channel, while a
separate outer `Client` connects the Host to the actual MCP Server. Keeping
those two connections separate prevents iframe negotiation and capabilities
from leaking into the server connection.
The View's `App` and the Host's `AppBridge` both subclass the base MCP SDK's
public `Protocol` for the iframe channel. A separate outer `Client` connects
the Host to the actual MCP Server. Keeping those two connections separate
preserves the Apps-only iframe handshake and prevents iframe capabilities from
leaking into the server connection.
