Model Context Protocol (MCP)
What is MCP?
Model Context Protocol (MCP) is an open standard designed to enable seamless integration between AI models (such as Large Language Models, LLMs) and external tools, services, or data sources.It was developed by Anthropic to simplify and standardize how AI applications interact with real-time information beyond their training data.What is MCP?
MCP acts as a universal connector for AI applications, similar to how USB-C standardizes hardware connectivity.Instead of building custom integrations for every tool or dataset, developers can implement MCP and immediately gain access to a wide variety of resources in a consistent and secure way.
MCP enables AI applications to:
- Access live data (files, databases, APIs)
- Use external tools for calculations, content generation, or system control
- Enhance contextual awareness beyond static training datasets
Core Components
MCP uses a client-server architecture:
- MCP Host: The AI application needing access to tools/data (e.g., Claude Desktop)
- MCP Client: A local connector inside the host that communicates with servers
- MCP Server: A lightweight service that provides access to data sources or capabilities using the MCP protocol
- Local Data Sources: Files or databases on the user's device
- Remote Services: APIs or cloud systems that the MCP server can connect to
Why Use MCP?
| Benefit | Description |
|---|---|
| Standardization | Provides a common interface for integrating tools and data with AI |
| Flexibility | Allows AI apps to work with multiple data sources and tool providers easily |
| Security | Supports secure local and remote access with authentication and authorization |
| Scalability | Enables building complex, multi-tool AI workflows efficiently |

Security Considerations
Implementing MCP requires attention to security best practices, including:
- Authentication and authorization checks
- Data encryption
- Access control policies
- Audit logging
A secure MCP setup ensures that only authorized AI models and users can access sensitive data.
