How to use prompt templates when building MCP tools

Following the course on building MCP tools on Graph Academy (link here), I can add resources, tools and prompts to the MCP server. However, I am not sure how the prompts could be used in practice. I have added the code for it and the server starts successfully but how can I use it from client's perspective?

One possibility as I can imagine is that the template prompts could be used just like in ChatGPT. After responding to an answer to my quesiton at the bottom of it ChatGPT also gives me some links that propose what other follow-up questions that I'd like to continue.

It does depend on your agent (IDE) but if you're using VS code you type /<MCP server>.<prompt> in the chat input.
