What is MCP?
MCP (Model Context Protocol) is an open protocol that standardizes how AI models connect to external data sources, tools, and services. It’s becoming the “HTTP of AI agents.”
Why MCP Matters
Before MCP, integrating AI with external tools required custom code for each integration. MCP solves this by providing:
- Universal Interface: One protocol for all integrations
- Reduced Development Time: No more custom connectors
- Ecosystem Growth: Tools work with any MCP-compatible agent
- Security: Standardized permission and access control
MCP Architecture
Core Components
- MCP Client: The AI model or agent
- MCP Server: The tool or data source
- Protocol: JSON-RPC based communication
Basic Flow
AI Agent (Client) → MCP Request → Tool/Service (Server) → Response → AI AgentImplementation Example
MCP Server (Tool Provider)
from mcp.server import Server
from mcp.types import Tool
server = Server("my-tool")
@server.list_tools()
async def list_tools():
return [
Tool(
name="search_database",
description="Search the company database",
inputSchema={...}
)
]
@server.call_tool()
async def call_tool(name, arguments):
if name == "search_database":
return search_resultsMCP Client (AI Agent)
from mcp.client import Client
client = Client()
# Discover available tools
tools = await client.list_tools()
# Use a tool
result = await client.call_tool("search_database", {"query": "sales 2024"})MCP vs Traditional Integration
