Coding Prompt Engineer MCP Server

This Model Context Protocol (MCP) server provides a tool to rewrite coding prompts for optimal results with Cursor AI and other AI IDEs, using Claude by Anthropic.

Installation

npm install

Install via Smithery

You can install this MCP server directly through Smithery by visiting: https://smithery.ai/server/@hireshBrem/prompt-engineer-mcp-server

Usage

Setting Environment Variables

The server requires an Anthropic API key to use Claude for formatting. Set it as an environment variable:

export ANTHROPIC_API_KEY=your_anthropic_api_key

If no API key is provided, the server will throw an error indicating the missing API key.

Running the Server

npm start

Or with MCP Inspector:

npx @modelcontextprotocol/inspector npm start

Tool: rewrite_coding_prompt

This tool takes a raw prompt and rewrites it for optimal results with Cursor AI and other AI IDEs.

Parameters

• prompt (required): The raw user’s prompt that needs rewriting
• language (required): The programming language of the code

Example Usage

{
  "name": "rewrite_coding_prompt",
  "arguments": {
    "prompt": "Create a function to convert temperature between Celsius and Fahrenheit",
    "language": "typescript"
  }
}

How It Works

The server uses Claude 3 Sonnet by Anthropic to intelligently rewrite your prompts for better results. It enhances your prompt by:

1. Adding clear structure and context
2. Specifying requirements and expectations
3. Including language-specific considerations
4. Optimizing for AI IDE understanding

Features

• Intelligent Prompt Engineering: Uses Claude 3 Sonnet to rewrite prompts for optimal results
• Language-Aware: Customizes prompts based on target programming language
• Easy Integration: Works seamlessly with Cursor and other AI IDEs
• Low Temperature Setting: Uses 0.2 temperature for consistent, structured output

Configuration

Usage with Claude Desktop

Add this to your claude_desktop_config.json:

NPX

{
  "mcpServers": {
    "cursor-prompt-engineer": {
      "command": "npx",
      "args": [
        "-y",
        "cursor-prompt-engineer"
      ]
    }
  }
}

Local Installation

# Clone the repository
git clone https://github.com/yourusername/cursor-prompt-engineer.git

# Run the server
node index.js

Example

Input:

Create a function that sorts an array of objects by a specific property

With arguments:

{
  "prompt": "Create a function that sorts an array of objects by a specific property",
