alt Hacker NewsMost MCPs I've seen could be:
1. A cli script or small collection of scripts
2. A very short markdown file explaining how it works and when to use it.
3. Optionally, some other reference markdown files
Context use is tiny, nearly everything is loaded on demand.
And as I'm writing this, I realize it's exactly what skills are.
Can anyone give an example of something that this wouldn't work for, and which would require MCP instead?

I'm with you because we get to specify our context more precisely.
I mean, one could argue skills are sort of MCP 2.0 fixing some of the mistakes.
The big pluses for MCPs are when:
1. They live remotely and update themselves 2. You install the skill and the scripts it uses together locally, so it can be more convenient packaging
MCPs aren't really all that complicated inherently, a lot of mistakes around them happened because they came early.
But this is entirely besides the point. The point of MCP is bundling those exact things into a standardized plugin that’s easy for people to share with others.
MCP is useful because I can add one in a single click for an external service (say, my CI provider). And it gives the provider some control over how the agent accesses resources (for example, more efficient/compressed, agent-oriented log retrieval vs the full log dump a human wants). And it can set up the auth token when you install it.
So yeah, the agent could write some those queries manually (might need me to point it to the docs), and I could write helpers… or I could just one-click install the plugin and be done with it.
I don’t get why people get worked up over MCP, it’s just a (perhaps temporary) tool to help us get more context into agents in a more standard way than everyone writing a million different markdown files and helper scripts.
