                          What is MCP
############################################################################
MCP (Model Context Protocol (MCP)) is a standard way for an AI to communicate 
with other systems and perform actions or retrieve data.

OR

A standardized protocol that lets AI models connect to and interact with 
external systems, tools, and data sources.


a) MCP Client → The AI application (ChatGPT, Claude, Cursor, etc.)
b) MCP Server → Exposes tools and data
c) Tools → Actions the AI can perform
d) Resources → Data sources (files, databases, APIs)



[++++++++++++++++++++++++++++++ MCP uses JSON messages. +++++++++++++++++++++++++++++++++++]

a) Client → Server
    {
	  "method": "tools/call",
	  "params": {
	    "name": "get_candidate",
	    "arguments": {
	      "id": 101
	    }
	  }
	}
b) Server → Client
	{
	  "result": {
	    "id": 101,
	    "name": "Alok",
	    "skills": [
	      "Python",
	      "Django"
	    ]
	  }
	}
