Exercise 2: Why the MCP Inspector Step Is Genuinely Useful — Possible Solution
====================================================================

Testing with the MCP Inspector lets you verify the server's own real
exposed surface - the component list, initial state, and available
specs - directly and in isolation, without also needing a real,
working AI agent client configured and connected at the same time. If
something is wrong with what the MCP server exposes (a missing
component, a malformed spec), the Inspector isolates that as a server-
side problem before an agent is ever involved, rather than leaving you
to guess whether a failure is coming from the server or from the
agent's own side of the connection.

This is a genuinely useful debugging step, not an unnecessary extra
one, because a real AI agent adds its own layer of complexity and
potential failure points (how the agent interprets what it's given, how
it decides to use the tools) on top of the server's own behavior. Ruling
out the server first, using a tool built specifically to inspect it
directly, narrows down where a real problem actually lives before
adding that extra layer of complexity into the mix.

ANSWER: The MCP Inspector is genuinely useful because it verifies the
server's own real exposed tools in isolation, without needing a
working agent connection at the same time - if something's wrong, this
step confirms whether the problem is on the server side before an
agent's own added complexity gets mixed into the picture, making real
problems easier to isolate rather than guess at.

WHY THIS WORKS AS AN ANSWER
------------------------------
This correctly explains the real debugging value of isolating the
server from the agent, rather than treating the Inspector step as
simply "extra testing for its own sake."
