Agree... this is an important blog. People need to press pause on MCP in terms of adoption...it was simply not designed with a solid enough technical foundation that would make it suitable to be an industry standard. People are hyped about it, kind of like they were for LangChain and many other projects, but people are going to gradually (after diving into implementations) that it's not actually what they were looking for..It's basically a hack thrown together by a few people and there are tons of questionable decisions, with websockets being just one example of a big miss.

The Langchain repo is actually hilariously bad if you ever go read the source. I can't believe they raised money with that crap. Right place right time I guess.

Yeah agree. I spent a few hours looking at the langchain repo when it first hit the scene and could not for the life of me understand what value it actually provided. It (at least at the time) was just a series of wrappers and a few poorly thought through data structures. I could find almost no actual business logic.

My first surprise on it:

I made an error trying with aws bedrock where I used "bedrock" instead of "bedrock-runtime".

The native library will give you an error back.

Langchain didn't try and do anything, just kept parsing the json and gave me a KeyError.

I was able to get a small fix, but was surprised they have no error like ConfigurationError that goes across all their backends at all.

The best I could get them to add was ValueError and worked with the devs to make the text somewhat useful.

But was pretty surprised, I'd expect a badly configured endpoint to be the kind of thing that happens when setting stuff up for the first time, relatively often.

Isn't that what a lot of this is about? It's a blue ocean and everyone are full of fomo.
