FastMCPTransport

In-memory transport for FastMCP servers. This transport connects directly to a FastMCP server instance in the same Python process. It works with both FastMCP 2.x servers and FastMCP 1.0 servers from the low-level MCP SDK. This is particularly useful for unit tests or scenarios where client and server run in the same runtime. Methods:

connect_session 

connect_session(self, **session_kwargs: Unpack[SessionKwargs]) -> AsyncIterator[ClientSession]
