Learn to build AI applications that access tools, data, and prompts using the Model Context Protocol (MCP) in this new course by DeepLearning.AI and Anthropic. MCP standardizes how LLMs interact with external systems, simplifying integrations for web searches, local documents, GitHub repos, and more.

You Should Know:

1. MCP Architecture Overview

MCP follows a client-server model:

  • MCP Client: Runs inside the AI app.
  • MCP Server: Exposes tools, data, and prompts (locally or remotely).

Key Components:

  • Tools: External APIs (e.g., web search, GitHub).
  • Resources: Data sources (documents, databases).
  • Prompt Templates: Predefined LLM instructions.

2. Hands-On Implementation

Step 1: Set Up FastMCP Server

 Clone the MCP Inspector repo 
git clone https://github.com/anthropic/mcp-inspector.git 
cd mcp-inspector

Install dependencies 
pip install fastapi uvicorn

Run the MCP server 
uvicorn server:app --reload

Step 2: Build an MCP-Compatible Chatbot

from fastapi import FastAPI 
from mcp_client import MCPClient

app = FastAPI() 
client = MCPClient(server_url="http://localhost:8000")

@app.post("/query") 
def query_llm(prompt: str): 
response = client.fetch_tools(prompt) 
return {"response": response}

Step 3: Connect to Anthropic’s Reference Servers

 Example: Fetch web content via MCP 
curl -X POST http://localhost:8000/fetch -d '{"url":"https://example.com"}'

Access filesystem tools 
curl -X POST http://localhost:8000/filesystem -d '{"path":"/docs/notes.txt"}'

3. Deploying MCP Remotely

Use Docker for remote MCP server deployment:

FROM python:3.9 
COPY . /app 
WORKDIR /app 
RUN pip install fastapi uvicorn 
CMD ["uvicorn", "server:app", "--host", "0.0.0.0", "--port", "80"]

Deploy on AWS/GCP:

docker build -t mcp-server . 
docker run -p 80:80 mcp-server

4. Testing with MCP Inspector

Anthropic provides MCP Inspector for debugging:

git clone https://github.com/anthropic/mcp-inspector 
cd mcp-inspector 
python inspector.py --server http://your-mcp-server

5. Future MCP Roadmap

  • Multi-Agent Architectures
  • MCP Registry API (discover public MCP servers)
  • Authentication & Authorization

What Undercode Say

MCP is a game-changer for AI developers, reducing fragmentation in LLM integrations. By standardizing client-server interactions, it enables seamless access to external tools—whether for web searches, local files, or APIs.

Key Linux/IT Commands for MCP Developers:

 Monitor MCP server logs 
journalctl -u mcp-server -f

Check network connections 
netstat -tulnp | grep 8000

Secure MCP with Nginx reverse proxy 
sudo apt install nginx 
sudo nano /etc/nginx/sites-available/mcp

Windows Equivalent (PowerShell):

 Check running MCP processes 
Get-Process -Name "uvicorn"

Test MCP server connectivity 
Test-NetConnection -ComputerName localhost -Port 8000

Prediction

MCP will dominate AI app development by 2025, replacing custom API integrations with a universal protocol for LLM context management. Expect enterprise adoption in RAG, autonomous agents, and AI automation.

Expected Output:

  • A running MCP server (local/remote).
  • A chatbot dynamically fetching tools/data via MCP.
  • Deployed MCP services accessible via Claude Desktop.
