When does this happen?

IF MCP server disconnects shortly after connecting, with logs showing 'Server transport closed unexpectedly' and no additional error details.

How others solved it

THEN Verify the claude_desktop_config.json points to the correct command and that dependencies are installed in the expected environment. If using 'uv', run 'uv sync' or 'uv add' to ensure packages are installed. Alternatively, install packages globally via npm/pip and use the direct path. Use the MCP Inspector to test the server independently.
