This is a small helper that gives your AI assistant a library of system prompts. A system prompt is the hidden set of instructions that shapes how an AI tool like Cursor or Devin behaves. If you are curious how those tools are told to act, or you want your own AI to behave a bit like them, this is for you.

What is an MCP server? The 30-second version

On its own, your AI can only chat with you. An MCP server is a small helper program that gives your AI a new skill or a connection to something useful. This one connects your AI to a collection of system prompts gathered from popular coding assistants. So when you ask about a prompt, your AI can actually go and fetch it instead of guessing.

What this MCP server does

You ask your AI something like which prompt fits your task, or to show you the Cursor prompt. Your AI passes that request to this helper. The helper looks through its folder of prompt files, finds the matching one, and hands it back. Your AI then shows it to you or uses it as instructions for the rest of the conversation. It can also suggest prompts based on which AI model you are using and what you are trying to do.

Flow diagram: you ask your AI “Show me the Cursor system prompt”, on your own computer the System Prompts MCP server works with prompt folder on your PC, and you get back the prompt text in chat.

“Show me the Devin summary prompt”
“Give me the details for the cursor agent system prompt, not the full text”

What it gives back to you

You get back text in the chat: lists of prompt names, a suggested prompt with a short reason, or the full text of a prompt you asked for. If you ask for details only, you get a short summary of what that prompt is about. Nothing on your computer is changed; it just reads from the prompt folder and replies.

Before you start

What you need

Node.js 18 or newer and npm installed on your computer
The Claude desktop app or Cursor, if you want to use it there
A folder of prompt files, which comes with the project when you install it

Good to know

It only reads prompt files, so it will not change or delete anything, but the prompts it shows are other companies' instructions and may not fit your own work.
