Prompt Engineering for Everyone: Making AI Workflows Reusable with MCP
We're entering a new era of AI interaction—one where people don't have to be "prompt engineers" to get the most out of large language models. Thanks to the Model Context Protocol (MCP), developers can now expose reusable, parameterized prompts directly to LLMs and users, making complex workflows accessible to everyone.
Let's dive into how MCP's prompt system works, why it's a game-changer for accessibility and productivity, and how you can use it to supercharge your own apps.
Why Prompts Matter
If you've ever used an LLM, you know that the right prompt can make all the difference. Include too little context, and the LLM will be unable to complete the task. Include too much, and the LLM will overemphasize the wrong details. But not everyone wants to (or should have to) craft the perfect prompt every time they need to summarize a document, generate alt text, or review some code.
Especially when you're developing a bunch of MCP tools and resources for the LLM to use, it can be really helpful to your users if you come up with common use cases that instruct the LLM on which tools and resources to use to accomplish a common task.
MCP's prompt capability lets you, as a developer, define a menu of reusable, structured instructions—each with a clear description and customizable arguments. Users can use these prompts in the UI of their LLM app, fill in the blanks, and get consistent, high-quality results.
Right now, Claude supports these via a special menu to add context, but other clients may have different ways of exposing them. Prompts are intended to be user-invoked, not automatically added to the conversation.
How MCP Prompts Work
With MCP, you can register prompts on your server like this:
server.prompt('summarize_document','Summarize a document for the user',{documentUrl: z.string().url().describe('The URL of the document to summarize'),readingLevel: z.enum(['child', 'teen', 'adult']).describe('Target reading level for the summary'),},async ({ documentUrl, readingLevel }) => ({messages: [{role: 'user',content: {type: 'text',text: `Please use the load_document tool to load the document at ${documentUrl} and summarize it at a ${readingLevel} reading level.`,},},],}),)
Now, any client (including LLMs) can discover this prompt, supply a document URL and reading level, and get a perfectly tailored summary—no prompt engineering required.
Now, go ahead and enhance this prompt to be perfectly tuned for your use case and it's easy for users to discover and use!
