It's an open protocol; where did you get the idea that it would only work with Claude? You can implement it for whatever you want - I'm sure langchain folks are already working on something to accommodate it

Once fully adopted by at least 3 other companies I'll consider it a standard, and would consider it yes, if it solved a problem I have, which it does not.

Lots of companies open source some of their internal code, then say it's "officially a protocol now" that anyone can use, and then no one else ever uses it.

If they have new "tools" that's great however, but only as long as they can be used in LangChain independent of any "new protocol".
