# Transports (tai42_kit.transport)

> UDS transports and the MCP transport factory.

MCP client transports over a unix-domain socket + the transport selector.

The UDS transports implement the contract `Transport` Protocol; `get_mcp_transport`
picks between them (or a plain dict-config for non-UDS servers).

## BaseUDSTransport

`tai42_kit.transport.base_uds_transport.BaseUDSTransport`

```python theme={null}
class BaseUDSTransport(ClientTransport)
```

**Attributes**

| Attribute     | Type |
| ------------- | ---- |
| `socket_path` | —    |

## HTTPUDSTransport

`tai42_kit.transport.http_uds_transport.HTTPUDSTransport`

```python theme={null}
class HTTPUDSTransport(BaseUDSTransport)
```

### Members

#### connect\_session

`tai42_kit.transport.http_uds_transport.HTTPUDSTransport.connect_session`

```python theme={null}
async connect_session(self, **session_kwargs: Any) -> AsyncGenerator[ClientSession]
```

**Parameters**

| Parameter        | Type  | Default | Description |
| ---------------- | ----- | ------- | ----------- |
| `session_kwargs` | `Any` | `{}`    | —           |

## SSEUDSTransport

`tai42_kit.transport.sse_uds_transport.SSEUDSTransport`

```python theme={null}
class SSEUDSTransport(BaseUDSTransport)
```

### Members

#### connect\_session

`tai42_kit.transport.sse_uds_transport.SSEUDSTransport.connect_session`

```python theme={null}
async connect_session(self, **session_kwargs: Any) -> AsyncGenerator[ClientSession]
```

**Parameters**

| Parameter        | Type  | Default | Description |
| ---------------- | ----- | ------- | ----------- |
| `session_kwargs` | `Any` | `{}`    | —           |

## get\_mcp\_transport

`tai42_kit.transport.utils.get_mcp_transport`

```python theme={null}
get_mcp_transport(config: TaiMCPConfig, *, uds_protocol: str = 'http') -> HTTPUDSTransport | SSEUDSTransport | dict[str, Any]
```

Build the fastmcp transport for one MCP server config.

A UDS server connects over a unix socket; `uds_protocol` selects the MCP
wire protocol carried on it (`http` = streamable-http, `sse` = SSE) — the
caller (which owns the runtime/CLI) supplies it, so it arrives unvalidated and
any other value raises. A non-UDS server returns a plain fastmcp dict-config
and ignores `uds_protocol`.

**Parameters**

| Parameter      | Type           | Default  | Description |
| -------------- | -------------- | -------- | ----------- |
| `config`       | `TaiMCPConfig` | —        | —           |
| `uds_protocol` | `str`          | `'http'` | —           |
