### 1. The "N x M" Integration Problem (The USB-C of AI 🔌)

Pehle: Har AI model (OpenAI, Claude, Llama) aur har developer tool (GitHub, PostgreSQL, Slack, VPS) ke liye custom spaghetti integration likhni padti thi ($N \times M$ APIs).  
**Model Context Protocol (MCP - Anthropic Universal Open Standard 👑):** **Single standardized JSON-RPC 2.0 interface!** 1 baar MCP Server banao, wo **Claude Desktop, Google Antigravity, Cursor, LangGraph sab par instantly plug-and-play kaam karega!**

```

                           ⬇ (Standardized MCP Protocol)
┌─────────────────────────────────────────────────────────────┐
│ MCP SERVERS (PostgreSQL, Git, Remoter, Canva, VPS SSH, DB)  │
└─────────────────────────────────────────────────────────────┘
```

### 2. The 3 Core Primitives of MCP

1. **Tools:** Model-callable executable functions (`execute_ssh`, `run_query`, `deploy_app`).
2. **Resources:** Read-only data payloads & file attachments (`file://logs/app.log`, `postgres://schema`).
3. **Prompts:** Pre-defined interactive prompt templates & slash commands.

### 3. Interview Ke 3 Sawal Is Topic Se

1. **MCP Language Server Protocol (LSP) se kaise inspired hai?** -> Jaise LSP ne saare IDEs (VSCode, JetBrains) ke liye single compiler interface standardise kiya, waise hi MCP saare AI models ke liye single Tool/Data interface standardise karta hai.
2. **JSON-RPC 2.0 specification MCP me kya role play karti hai?** -> Request/Response payloads (`id`, `method: "tools/call"`, `params: { name, arguments }`) ka lightweight universal standard format ensure karna.
3. **MCP security boundaries client-side par kaise enforce hoti hain?** -> MCP client har tool execution se pehle user consent prompt ya sandbox boundaries enforce karta hai.
