CLIs have to be distributed. Also have to be kept up to date. An MCP doesn't t have to concern itself with backwards compatibility and can be changed willy nilly since it's essentially always up to date.

It's also easier to manage for non-tech people. Try telling the people over at HR or finance to install a CLI.

>> MCP consumes ~65x more tokens than the CLI approach.

For this example, there seems to be no explanation for the LLM to know when to use this curl command, etc. Is the idea that the linear API is known in the LLM weights already and therefore there is no need to include "the manual" in the context window? If so, it's a pretty narrow win.

I run the team at OpenAI that's responsible for the ChatGPT App Store, Codex plugins, and all things MCP. The thing that all these "MCP is dead" posts are missing is that whether or not MCP is used as a transport protocol is actually completely irrelevant. The reason MCP isn't dead is because practically ~every company on the planet is building an MCP server. I know this because we interact with all of them. Most of…

Have you heard of the Ask Protocol? (https://abject.world/ask-protocol/).

I might be biased because I came up with it, but we are over complicating these systems. There is a simpler way, and it appears to work well since I built a system using it to test the idea.

Earlier quoted context omitted.

I would bet that MCP is going to die. The main reason is that it adds another layer (and human) that can, and probably will, get out of sync with the real-world implementation, whether that implementation is an API, web, or a CLI. AI should not be using a protocol or set of instructions that is different from what humans have access to (know and use). Sure, companies want to expose MCP servers because it is the cool…

Soon, if you want the performance of your AI clients to improve (wrt. token count and understanding) you will start to customize the output of the MCP server for more synthetic data, different data types, more permissive inputs, etc. And since most your clients will be AI that might be your API that fall behind, and MCP that will be maintained. That's at least my experience with my current project: the traditional js…

Interesting points. A couple of questions. Do you have a frontend (React, Vue, anything) and if you do, does it interact with the server using the MCP server or the JSON API? Are all your clients AIs or do you expect that most of them will be AIs?

The reason I'm asking those questions is that a customer of mine has a service with a JSON API, a Vue frontend and a score of customers using that JSON API. We know that the newest ones are using bots to code their clients (and they are using them wrong, by the mistakes they do.) I don't see a near future in which all those third party apps become LLMs that would benefit from a MCP server and we retire the API.

I use all three (MCP/CLI/API) based on what Claude excels at: * CLI: GitHub & AWS it already knows how to operate the CLIs well. Even learned about a few new CLIs like 1Password's op which it volunteered one day. * MCP: Supabase, Shopify etc. where the CLI would be non-obvious and the affordances from the tools/descriptions helps Claude maneuver. * API: Sometimes it just knows an API exists and is able to call it dir…

Also MCPs for programs like Chrome Dev tools or Playwright.

What comes after CLI?

In the early days of computing, desktop apps and later webapps provided richer human experiences.

What will provide richer experiences for agents, after CLIs?

But then there is the other side that companies are adding MCP servers to stuff that has never had a public API.

> The reason MCP isn't dead is because practically ~every company on the planet is building an MCP server. I know this because we interact with all of them. Wow if that's not an echo-chamber comment I don't know what is.

Resist the urge to nitpick and accept that the poster simply means "a large number of high-profile companies".
