Repro
Since last week or two, I started getting such dialogue each time I connect to my VSCode remote host or open Copilot chat (this happens on every single VSCode remote host I am conneсting to, different Python and Ubuntu versions):
Considering totally anonymous nature of this popup (red flag №1) Took me a while to figure what extension / feature it comes from, and turnes out, it is Pylance MCP server that causes it:
My first urge was to disable this MCP, as I have NEVER authorized installing and running it (red flag №2), so I open list of MCP servers and, indeed I can see Pylance there:
Yet, when I go to Extensions bar to remove Pylance MCP, it is not on the list (red flag №3):
I have two questions:
- how to get rid of this annoying Dynamic Client popup?
- how to disable Pylance MCP, as it is not needed for my level of work with Python anyway?
Thank you.
