## 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.
