+    Nexus MCP Transport for use in Temporal workflows.
+
+    This class provides a transport that proxies MCP requests to a Temporal Nexus service. It can be
+    used to make MCP calls via `mcp.ClientSession` from Temporal workflow code.
+
+    Example:
+        ```python
+        async with WorkflowNexusTransport("my-endpoint") as (read_stream, write_stream):
+            async with ClientSession(read_stream, write_stream) as session:
+                await session.initialize()
+                await session.list_tools()
+                await session.call_tool("my-service/my-operation", {"arg": "value"})
+        ```
