Your Idea

I would like to leverage MCP to handle the problem of prompt libraries not being client agnostic in current AI apps. This removes the need for proprietary prompt lifecycling / sharing in apps if can standarize around MCP

Leveraging the prompts protocol, we can:

• ship a prompt library that is 100% agnostic to the client app that loads the library. Any app
• standardize around the protocol's dynamic prompt schema
• provide RBaC to different prompts just like any other file system access

However where I am stuck at at the moment is how to be able to register new prompts on a live running server without having to redeploy the server. Is this already possible?

The goal here is that

1. I want users to be able to post new prompts on the live remote server that get registered and shipped to clients in a prompt update
2. I don't want all users registering prompts to need to be engineers that can write code. A crud rest api that can be exposed on a form / frontend w/ oauth to permit registering / removing a prompt from the server. A ui that meets the protocol schema for prompts could let any human write complex dynamic workflow prompts.

Would this application actually need to be built into the protocol such that a mcp client could call a create / delete / update prompt, or just a pattern we can work into the SDK's?

Unlike tools that actually execute code, prompts and resources generally just follow a schema which while certainly can be enhanced with dynamic imperative code server side; don't need to be to be able to define.

This way organization prompt / resource libraries can be managed through MCP without having to reinvent the wheel for each new app and can auto load the library fully portable any new app we want to try.
