Ask HN: Is the future everyone having 100 MCP processes running on their PC?
Some things I don't understand with MCP vs. CLI Permissions: you can already scope CLI command permissions Discoverability: you can already discover commands/arguments with a help flag Why add a whole other process to the computer? Do MCP proponents imagine in the future every program on your PC has another MCP process also running? It seems like adding extra complexity/moving parts for not much benefit. 2 comments on Hacker News.
