Description
There isn't much documentation on testing and it isn't clear what the recommended and supported way of unit testing MCP endpoints are?
As a unit test it shouldn't involve a sub-process or actually opening an port. But it should test enough of the MCP integration to ensure the endpoint would work, and wouldn't hit unexpected serialization issues etc.

Research direction
No file or test path is identified in the issue. Start by locating the TypeScript SDK's MCP endpoint integration and existing endpoint tests, then document a supported in-process unit-test approach that exercises serialization without a subprocess or open port; done when the recommended setup and coverage are clear.
