MCP Is Becoming the New USB-C: Necessary, Imperfect, Unavoidable
Pi.dev published a post explaining why they said no to MCP, and the HN thread pushed back in an interesting way. The loudest counterargument wasn't that MCP is great, it's that USB-C isn't great either, HDMI isn't great, NVMe isn't great, and we use all of them anyway because a bad standard beats no standard. The thread noted the post conflates Codemode and MCP as distinct new features, suggesting even informed users are struggling to track what the protocol actually covers.
The pattern: MCP is rapidly becoming the default integration layer for AI agents talking to tools, whether or not developers think it's the right design. The debate is shifting from 'should we adopt it' to 'how do we live with it.' That's a meaningful inflection point.
For builders, the Pi.dev thread is useful precisely because of its reluctance. The objections are real. But the conclusion that something is better than nothing is winning in practice.
So what?
If you're building tools that need to talk to AI agents, MCP is becoming the path of least resistance regardless of its design flaws. Holding out for a better standard is a reasonable technical position but a risky product strategy. At minimum, understand the protocol well enough to know what you're accepting.
