Re: WebML CG Teleconference – 19 February 2026 - 16:00-17:00 UTC

Dear Anssi,

Nice meeting you and others

The new  meeting time slot is difficult for me, but do not let me hold
anyone back

I do not often manage to attend meetings in person and prefer to make my
contributions via list, so  thanks for posting

I forked the MCP repo and made a generator with tutorial on/off
https://starborn.github.io/webmcp/

I would like to bring attention to some folders in the fork: specifically
technical notes which aim to track the history or webMCP came into being
as well as where it may be going, as well as a learning tool  ane how to
make contributions to the draft spec

Please let me have corrections, amendments so that I may publish v 2 after
revisions and continue to learn more

*admitting deep aversion to github some folders here
