That solution will not work as well when the interfaces have not been standardized in a way that makes it so easy to import them into a script as a library.
Coding against every subtly different REST API is as annoying with agents as it is for humans. And it is good to force vendors to define which parts of the interface are actually important and clean them up. Or provide higher level tasks. Why would we ask every client to repeat that work?
There are also plenty of environments where having agents dynamically write and execute scripts is neither prudent nor efficient. Local MCP servers strike a governance balance in that scenario, and remote ones eliminate the need entirely.
It's not particularly hard for current models to wire up a http client based on the docs and every major company has well documented APIs for how to do so either with their SDKs or curl.
I don't know that I really agree its as annoying for agents since they don't have the concept of annoyance and can trundle along infinitely fine.
While I appreciate the standardization I've often felt MCPs are a poor solution to a real problem that coincided with a need for good marketing and a desire to own mindspace here from Anthropic.
I've written a lot of agents now and when I've used MCP it has only made them more complicated for not an apparent benefit.
MCP's value lies in the social alignment of people agreeing to use it, it's technical merits seem dubious to me while its community merits seem high.
I can accept the latter and use it because of that while thinking there were other paths we probably should have chosen that make better use of 35 years of existing standards.
Well if everyone was already using Swagger then yes it would be a moot point. It seems you do in fact agree that the standardized manifest is important.
If everyone had a clear spec with high signal to noise and good documentation that explains in an agent-friendly way how to use all the endpoints while still being parsimonious with tokens and not polluting the context, then yes we wouldn't need MCP...
Instructing people how to do that amounts to a standard in any case. Might as well specify the request format and authentication while you're at it.
I don’t get your point. Obviously some spec is needed but why does it have to be MCP?
if I want my api to work with an llm id create a spec with swagger. But why do I have to go with mcp? What is it adding additionally that didn’t exist in other spec?
You can ask an AI agent that question and get a very comprehensive answer. It would describe things like the benefits of adding a wire protocol, having persistent connections with SSE, not being coupled to HTTP, dynamic discovery and lazy loading, a simplified schema, less context window consumption, etc.
Yep. And those that did implement the standard did so for a different set of consumers with different needs.
I'm also willing to make an appeal to authority here (or at least competitive markets). If Anthropic was able to get Google and others on board with this thing, it probably does have merit beyond what else is available.
