Introduced by Anthropic in November 2024, Model Context Protocol, or MCP for short, has provided a new standard for AI assistants to connect to data systems. This blog post is inspired by Fireship’s video: I gave Claude root access to my server... Model Context Protocol explained.

The developer world is buzzing about Model Context Protocol (MCP), and the excitement is justified. This emerging standard for building APIs has quickly gained momentum, becoming an official standard in the OpenAI agents SDK just a while ago. For developers familiar with REST, GraphQL, RPC, or even SOAP, MCP represents a fundamental shift in how we think about API architecture in an AI-driven world.

Model Context Protocol is a standardized way to connect AI models with external data and systems. Think of it as a "USB-C port for AI applications" - a universal interface that allows large language models to seamlessly interact with your existing infrastructure.
Developed by Anthropic, the team behind Claude, MCP addresses a critical need: giving LLMs structured access to real-world data and the ability to perform actions beyond text generation.

MCP represents more than just another API standard, it's part of a broader movement toward what called "vibe coding," where developers focus on outcomes rather than implementation details, leveraging AI to handle the heavy lifting of code generation and system integration.
This shift is significant because it democratizes complex integrations by abstracting away traditional API complexity, enables AI agents to work with real data rather than just training data, and provides a standardized approach for connecting any AI model to any system. The result is a dramatically reduced barrier to entry for building AI-powered applications.

MCP follows a familiar client-server pattern, but with AI-specific optimizations:
The client (such as Claude Desktop, Cursor, or Wisor) initiates requests and manages the AI interaction. You can even build custom clients for specific use cases.
Meanwhile, developers build MCP servers that expose two main types of interfaces:
Resources provide contextual information to AI models without side effects:
