Pretty interesting take on where value will accrue once MCPs are mature in the AI stack, using lessons from the proliferations of APIs earlier. “That era taught us something fundamental: once the connection layer is standardized, value doesn’t live there. It moves upstream to infrastructure providers who power the system, and downstream to vertical specialists who solve hard, domain-specific problems. The middle layer that acts as the glue gets squeezed. The same will happen with MCPs. Standardization creates new opportunities, but it also kills entire categories of shallow integration businesses. Some will mistake protocol adoption for defensibility. They’ll be wrong.” open.substack.com/pub/leo..
