Awesome Cursor MCP server

This MCP server provides an AI-powered development toolkit, offering intelligent coding assistance through custom AI tools for Cursor. It includes features like code architecture planning, screenshot analysis for UI design, and automated code reviews.

Installation and Setup

Environment Setup

First, set up your environment variables by creating a file at src/env/keys.ts:

export const OPENAI_API_KEY = "your_key_here";
// Add any other keys you need

⚠️ Security Note: Storing API keys directly in source code is not recommended for production environments. You can also set the env var inline in the Cursor MCP interface.

Installing Dependencies

Install the required dependencies:

npm install
# or
yarn install

Building the Server

Build the server:

npm run build

Configuring in Cursor

To add this MCP server to Cursor:

1. Open Cursor
2. Go to Cursor Settings > Features > MCP
3. Click + Add New MCP Server
4. Fill out the form:
   • Name: AI Development Assistant
   • Type: stdio
   • Command: node /path/to/your/project/dist/index.js

Pro Tip: Use the full path to your project's built index.js file.

After adding the server, your tools should appear under "Available Tools". If they don't appear, try clicking the refresh button in the MCP server section.

Using the Tools

Once configured, you can use these tools directly in Cursor's Composer:

Code Architect

This tool calls advanced reasoning LLMs to generate plans and instructions for coding tasks. To use it, try typing in Composer:

• "Help me architect a new feature"
• "Plan the implementation of a login system"

Screenshot Buddy

Take and analyze UI design screenshots. Example prompt:

• "Analyze this UI screenshot"
• "Help me improve this interface design"

Code Review

Trigger code reviews using git diffs. Example prompts:

• "Review this code for best practices"
• "Check my recent changes for issues"

The agent will ask for your approval before making any tool calls.

Pro Tip: You can update your .cursorrules file with instructions on how to use the tools for certain scenarios, enabling automatic tool usage by the agent.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "ai-development-assistant" '{"command":"node","args":["/path/to/your/project/dist/index.js"],"type":"stdio"}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "ai-development-assistant": {
            "command": "node",
            "args": [
                "/path/to/your/project/dist/index.js"
            ],
            "type": "stdio"
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "ai-development-assistant": {
            "command": "node",
            "args": [
                "/path/to/your/project/dist/index.js"
            ],
            "type": "stdio"
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
