MCP Resume Assistant

A sophisticated Model Context Protocol (MCP) server implementation that enables AI assistants to intelligently interact with resume/CV data and handle email communications. The project combines a powerful backend MCP server with an elegant Next.js frontend playground for testing and demonstration.

🎯 Overview

This project implements an MCP server that provides two main capabilities:

• CV/Resume Intelligence: Parse, understand, and answer questions about CV content
• Email Communication: Send professional emails using the Resend API

The system is designed to showcase how MCP servers can bridge AI assistants with real-world data and services, making them more practical and useful.

📧 Email Capabilities

• Professional Email Sending: Integration with Resend API for reliable email delivery
• Form Validation: Comprehensive validation using Zod schemas
• Error Handling: Graceful error handling with user-friendly messages
• Real-time Feedback: Live status updates during email sending

🎨 Modern Frontend

• Interactive Chat Interface: Conversational UI for CV questions
• Predefined Quick Questions: One-click access to common queries
• Real-time Email Form: Professional email composition interface
• Responsive Design: Optimized for desktop and mobile devices
• Beautiful UI: Modern design with Tailwind CSS and smooth animations

🚀 Getting Started

Prerequisites

• Node.js 18+
• npm or yarn
• Resend API Key (for email functionality)

Installation

1. Clone the repository

   git clone https://github.com/adeeshperera/mcp-resume-assistant.git
   cd mcp-resume-assistant

2. Install dependencies

   npm install

3. Set up environment variables

   cp .env.example .env.local

   Edit .env.local and add your Resend API key:

   RESEND_API_KEY=your_resend_api_key_here
   NEXT_PUBLIC_APP_URL=http://localhost:3000

4. Add your resume

   Place your PDF resume in the public/ directory as adeesh_perera_resume.pdf or update the path in src/server/tools/cv-chat.ts.

Running the Application

📡 API Endpoints

MCP API (/api/mcp)

POST - Ask questions about the CV

// Request
{
  "question": "What skills does Adeesh have?"
}

// Response
{
  "success": true,
  "answer": "Here's information about skills:\nJava / Spring Boot, Spring JPA..."
}

Email API (/api/email)

POST - Send emails

}

🔧 Configuration

Environment Variables

Variable	Description	Required
RESEND_API_KEY	Resend API key for email functionality	Yes
NEXT_PUBLIC_APP_URL	Public URL of the application	No

Customization

Adding Your Own Resume

1. Replace public/adeesh_perera_resume.pdf with your resume
2. Update the file path in src/server/tools/cv-chat.ts if needed
3. The system will automatically extract and cache the CV data

Modifying CV Parsing Logic

Edit src/server/services/cv-parser.ts to customize:

• Section keywords for better extraction
• Response formatting
• Question interpretation logic
