# `fastmcp.client.transports.memory`
## Classes
### `FastMCPTransport` <sup><a href="https://github.com/jlowin/fastmcp/blob/main/src/fastmcp/client/transports/memory.py#L14" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>
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` <sup><a href="https://github.com/jlowin/fastmcp/blob/main/src/fastmcp/client/transports/memory.py#L33" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>
```python
connect_session(self, **session_kwargs: Unpack[SessionKwargs]) -> AsyncIterator[ClientSession]
```
