Sean Lynch comments on Hacker News about the value of MCP (Model Context Protocol), highlighting its ability to isolate the auth flow outside the agent's context window and potentially out of the harness entirely. He suggests the idealized MCP might just be an auth gateway, but that alone would be a win.
