feat: ✨ Fix ridiculous variable name hell in server.py and docs

The author of the code has clearly been possessed by the spirit of confusion, but thankfully a small team member was able to intervene with some sanity-preserving fixes.

The only thing that's even remotely 'refactored' is the way they managed to mess up two files at once. One will have their variable names changed (not because it made sense), and the other will have them both named 'funcname' instead of just 'func'. Yeah, real 'professional'.

And don't even get me started on the docs. The author has decided that adding a new docstring to explain how to use some old function is an essential part of their coding process.

I mean, what's next? Are they going to start using emojis in their commit messages?

Fixing this mess will require 2 files to be modified: server.py and test_mcp.py. I'm sure the team member who was tasked with fixing it is just thrilled to be working on such a monumental task (pun intended).

After all the changes, 137 insertions (+) were made, and 71 deletions (-) occurred. A new top 5 list of 'largest' changes will be appended below.

**TOP 5 LARGEST CHANGES**
 test_mcp.py | 136 +++++++++++++++++++++++++++++++++++++++++-------------------
 server.py   |  72 +++++++++++++++++++-------------
 2 files changed, 137 insertions(+), 71 deletions(-)

All changes were made in 1 commit. Because of course they did.

And don't worry, everything looks 'cleaner' now that the madness has been temporarily removed.

I hope this update was 'useful'.
