I agree that interface would be a better name than protocol, but Model Context Integration/Integrator would be even better as that is it's core intent: To integrate context into the model. Alternatively, Universal Model Context Interface (or integrator) would be an even better name imo, as that actually explains what it intends to do/be used for, whereas MCP is rather ambiguous/nebulous/inaccurate on the face of it as previously established further up-thread.

That said, I think as the above user points out, part of the friction with the name is that MCP is two parts, a framework and a standard. So with that in mind, I'd assert that it should be redefined as Model Context Interface Standard, and Model Context Interface Framework (or Integration or whatever other word the community best feels suits it in place of Protocol).

Ultimately though, I think that ship has sailed thanks to momentum and mindshare, unless such a "rebranding" would coincide with a 2.0 update to MCP (or whatever we're calling it) or some such functional change in that vein to coincide with it. Rebranding it for "clarity's sake" when the industry is already quite familiar with what it is likely wouldn't gain much traction.
