What is MCP?

MCP stands for Model Context Protocol.
It’s a new open standard created by OpenAI (and others) that defines how AI models (like GPT-5) can connect to external tools, data sources, or systems in a secure, structured, and standardized way.

In simple terms:

MCP is a bridge between your AI model (like ChatGPT) and the real world — APIs, databases, internal company systems, or developer tools.

Why MCP is Used

Traditionally, AI models (LLMs) have limitations:

• They don’t know your private data (like codebases, databases, docs).
• They can’t safely connect to your tools (like GitHub, Slack, Jira, or MySQL).
• They can’t act directly (like running scripts or sending emails).

MCP solves all these problems by providing a secure “plugin-style” connection between the AI and external systems.

It’s like giving your AI controlled superpowers — it can now:

• Fetch live data from APIs.
• Read/write to your…
