Not only does the context7 MCP fail to work, but all MCPS are also unavailable. This is a very serious issue. Please fix it as soon as possible :)
mcp working fine here - potentially an issue with
npx? I'm on0.27.0(worked on all prior versions).Yo @guidedways, you the Windows version of VS Code?
when will this be fixed? It still occurs in yesterday's v.0.30
