yeah, i was comparing MCP clients to browsers. connecting to an MCP shouldn't leave you vulnerable to RCE on your host.
also, the way MCP servers are presented right now is in sort of a "marketplace" fashion meaning it's not out of the question you could find one hosted by a bad actor. PyPI/npm are also like this, but it's different since it's not like you can vet the source code of a running MCP. packages are also versioned, unlike MCP where whoever is hosting them can change the behaviour at any time without notice.
