When does this happen?

IF npx-based MCP servers fail to start in Claude Desktop while Python-based servers work, and background npx processes persist after the app is closed.

How others solved it

THEN Update Claude Desktop to version 0.7.5 or later. This version correctly detects npx-launched MCP servers and cleans up background processes on app exit.
