Introduction to MCP

Model Context Protocol (MCP) is a standardized way for AI models to interact with external tools and services. It defines how:

• Tools are described and presented to models
• Models can request tool execution
• Results are returned to models

Getting Started

To create an MCP server, you'll need:

• Node.js environment
• Basic understanding of REST APIs
• Familiarity with async/await patterns
• Understanding of JSON schemas

Core Concepts

1. Tool Definitions

• Function schemas
• Parameter validation
• Return types

2. Request/Response Flow

• Tool invocation
• Result handling
• Error management

3. Authentication & Security

• API keys
• Rate limiting
• Access control

Implementation Guide

Detailed implementation steps will be added in separate markdown files covering:

1. Basic server setup

2. Tool definition implementation

3. Request handling

4. Response formatting

5. Error handling

6. Testing and validation

Best Practices

• Keep tool descriptions clear and concise
• Implement proper error handling
• Use TypeScript for better type safety
• Follow security best practices
• Implement proper logging
• Add comprehensive documentation

Examples

Example implementations will be provided for:

• Basic tool server
• File operation tools
• API integration tools
• Database operation tools
