I don’t follow. It’s the other way around. Would you rather run an arbitrary binary blob (aka: a random cli) or `curl`? Edit: Maybe to clarify, I’m talking about remote MCP. Local MCP is obviously nonsensical. Remote MCP is very much thriving aggressively.

If the random blob is running inside of a real sandbox (Landlock/Bubblewrap, VM, ...Docker) then I would take the blob, because I can reason about its capabilities without inspecting its internals. The LLM can run curl as much as it wants if I've `unshare()`d its network access. MCP is an instant obligatory sandbox escape unless I also manage to deploy all the MCP servers inside the sandbox.

And yes, sorry, I was talking about local MCP. I should have made that clear. I do see people using local MCP quite a bit (Ghidra MCP, Playwright MCP, etc), but maybe this is more of a hobbyist thing.

Are there actual people suggesting this or did you combine multiple posts that were arguing different things?

The parent suggests MCP as a way to secure credentials and enforce guardrails, and sibling comments iterate on this. I might be reading a bit between the lines with my comment, but did not intend to derail the discussion.

But the parent who suggested MCP for security didn't say anything about vibe coding it. The person who talked about vibe coding an MCP was the one saying MCP isn't very useful.

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…

So because people are doing it, it's the right thing to keep? There is a long way to go before we know the shape of the real solution. Don't let things like MCP slow down the exploration

> I have some hope that this'll all lead to a revival of semantic web / microformats / etc Why would it? Do you see any agents or models use that? No, instead vibe coders at Anthropic vibe-designed a bespoke protocol that sidesteps and ignores the last 60 years of API development and integrations.

That was exactly my thought when I saw MCP: like we know so much about creating protocols but get a bunch of people together with no experience and that’s what you get. Reminds me a lot of Microsoft’s WS-disaster of the early 2000s except the latter was thought through a little better. To be fair a while back I did design an API for a general purpose model trainer which was absolutely atrocious for a few reasons, my…

Got any tips for building a MCP over CLI app?

clickbait. they knew what they were doing.

there's a long history of X is dead posts. PHP is dead, Java is dead, jquery is dead, unix is dead, REST is dead, graphql is dead, microservices is dead. and of course none of those things are dead. but... they're great for clickbait.

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…

+1 - MCP is a transient effect of current models’ limitations. But the “when” is relevant
