All influencer content is groan-inducing, but the idea behind MCP is pretty huge: it's the ability to link LLM agent loops into basically arbitrary APIs. It would be weird if it wasn't attracting a lot of attention.
Tool-calling is pretty huge, but MCP (a standard for calling a tool over HTTP) is way over-hyped, and neither here nor there really.
As a developer the hype is over the top for sure, but for the average marketer or influencer I can see how it is warranted.
Now if there is a good way to deal with authentication and authorization piece without agents gone wild that would excite me as a dev a lot more at this point.
