Ah, I could very much see this being used widely, especially where the enterprise-provided MCPs dont-quite-do what's needed - which is very common across APIs (where the permissions are fine but the APIs just aren't built in a particular way)!
And - similar question on this thread, do they persist? Can they be shared? (E.g. hey team clone my MCP-addon to use this like I do)
