MCP Prompt Engine

This is a small helper program that stores your own prompt templates and hands them to your AI when you need them. Instead of retyping the same instructions every time, you save them once and reuse them. It is handy for anyone who writes the same kinds of prompts over and over, like commit messages, emails, or reports.

What this MCP server does

You keep a folder of prompt files, each one written with simple placeholders like a name or a type. You ask your AI to use one of those prompts, and the AI asks this helper for it. The helper reads the file, fills in the placeholders with the details you gave, and hands the finished prompt back. Your AI then follows that prompt as if you had typed it yourself. If you edit a file, the helper notices and uses the new version right away.

What you can do with it

• Save your favourite prompts once and reuse them any time
• Fill in blanks like a name, a date, or a type when you pick a prompt
• Reuse shared pieces across several prompts so you only write them once
• Add simple logic like if-this-then-that inside a prompt
• Check your prompt files for mistakes before you use them
• Preview what a finished prompt will look like in your terminal
• Edit a prompt file and see the change without restarting anything

Try asking your AI

• “Use my git_stage_commit prompt with type feat”
• “Show me the list of prompts I have saved”
• “Run my weekly report prompt for this week”
• “Use the email_reply prompt and fill in the customer name”

What it gives back to you

You get the finished prompt text, already filled in with your details, shown right in the chat. Your AI then acts on it, so you see the answer or the work it did, not just the prompt. If you ask for a list, you get the names and short descriptions of your saved prompts.
