)


class EventMCPLifespan(BaseLifeSpan):
    def __init__(self, app: Unfazed) -> None:
        super().__init__(app)
        self.mcp_lifespan_context = None

    async def on_startup(self) -> None:
        self.mcp_lifespan_context = event_app.lifespan(self.unfazed)
        if self.mcp_lifespan_context is not None:
            await self.mcp_lifespan_context.__aenter__()

    async def on_shutdown(self) -> None:
        if self.mcp_lifespan_context is not None:
            await self.mcp_lifespan_context.__aexit__(None, None, None)
