Here is the answer from Gemini:

> Google's Web Model Context Protocol (WebMCP) handles authentication by inheriting the user's existing browser session and security context. This means that an AI agent using WebMCP operates within the same authentication boundaries (session cookies, SSO, etc.) that apply to a human user, without requiring a separate authentication layer for the agent itself.

Here’s what Gemini says about copy-pasting AI answers:

> Avoid "lazy" posting—copying a prompt result and pasting it without any context. If the user wanted a raw AI answer, they likely would have gone to the AI themselves.
