## SSE con `POST` { #sse-with-post }

SSE funciona con **cualquier método HTTP**, no solo con `GET`.

Esto es útil para protocolos como [MCP](https://modelcontextprotocol.io) que hacen streaming de SSE sobre `POST`:

If you declare the return type, FastAPI will use it to **validate** the data, **document** it in OpenAPI, **filter** it, and **serialize** it using Pydantic.

/// tip

As Pydantic will serialize it in the **Rust** side, you will get much higher **performance** than if you don't declare a return type.

        if self.call is None:
            return False  # pragma: no cover
        unwrapped = _unwrapped_call(self.call)
        return isinstance(unwrapped, SecurityBase)

    # Mainly to get the type of SecurityBase, but it's the same self.call
    @cached_property
    def _security_scheme(self) -> SecurityBase:
        unwrapped = _unwrapped_call(self.call)
        assert isinstance(unwrapped, SecurityBase)

    Use as `response_class=EventSourceResponse` on a *path operation* that uses `yield`
    to enable Server Sent Events (SSE) responses.

    Works with **any HTTP method** (`GET`, `POST`, etc.), which makes it compatible
    with protocols like MCP that stream SSE over `POST`.

    The actual encoding logic lives in the FastAPI routing layer. This class

 * If your authentication may be flaky and requires retries you should apply some policy
 * to limit the retries by the class of errors and number of attempts.  To get the number of
