Agree that for mainstream use it needs to be and will be hidden from the user entirely.

Will be much more like an app store where you can see a catalog of the "LLM Apps" and click to enable the "Gmail" plugin or "Shopping.com" plugin. The MCP protocol makes this easier and lets the servers write it once to appear in multiple clients (with some caveats I'm sure).

They feel quite similar to Alexa skills, packaged in a standard form. The app store analogy allows them to be searched by the end user.

TBH, it's quite surprising (and reassuring) that they have standardised as MCPs so soon. It normally takes a decade of walled gardens and proprietary formats before any open standards emerge.
