Thanks @sveneld - it will take some time for me to give some proper feedback here, just to let you know - needs quite some focus & attention - still really appreciated!

chr-hertel

Hi again @sveneld! This is great already - went to a first round of very detailed review directly. Thanks again for working on this! 🙏

Didn't manage to go through all, but dropping the first round of comments.

Done.

Great. Looks good.

I only have small things to comment at. I have not tested it out.

I have updated the pull request, but I am not satisfied with the result. I need more time to rethink the flow and improve the implementation.

chr-hertel · 2026-02-17T23:26:51Z

@sveneld anything in particular you would need feedback here?
can tell you about nit picks already, e.g. using Mcp\Exception\*Exception classes instead of built-in ones

sveneld · 2026-02-18T12:03:19Z

Thank you, no feedback needed.

sveneld · 2026-02-22T11:43:14Z

@chr-hertel take a look.

@chr-hertel take a look.

@sveneld will do so this weekend - thanks! 👍

Hi @sveneld, getting into polishing here I feel - thanks again for your work! Pretty sure i missed some parts, but you get the overall vibe of my review i guess.

Could you as well add some docs, especially what users would need to enable this feature? or could be a follow up PR if you like
