38. Model Context Protocol (MCP)#
MCP, is an open standard designed to enable seamless, secure, and structured communication between AI-powered applications—most notably large language models (LLMs)—and external data sources or tools.
MCP works by defining a universal client-server architecture: AI applications (acting as MCP clients) interact with various external systems (MCP servers), which expose specific tools, data resources, or reusable prompts. [1] [3] [5] [6] [7]
The protocol, built on JSON-RPC 2.0, acts as a common “language” allowing AI assistants to call functions, fetch real-time data, or use predefined templates from any connected service in a standardized way. This makes it far easier for LLM-based agents to access up-to-date information and capabilities without custom coding for each integration, similar to how USB provides a universal connector for computer peripherals. MCP has quickly gained traction in both open-source and commercial AI ecosystems and is a foundational technology for modern agentic AI systems and enhanced LLM deployments. [4] [5] [6] [7]

Example MCP JSON-RPC messages for invoking a tool, following the MCP protocol’s structured request-response flow for tool calls.
Tool Invocation Request (tools/call)
{
"jsonrpc": "2.0",
"id": 3,
"method": "tools/call",
"params": {
"name": "echo",
"arguments": {
"message": "Testing 123"
}
}
}
This request asks the server to execute the tool named echo with the argument message: "Testing 123".
Successful Invocation Response
{
"jsonrpc": "2.0",
"id": 3,
"result": {
"content": [
{ "type": "text", "text": "Echo: Testing 123" }
]
}
}
The server replies with the results of the tool execution. The output structure is determined by the tool’s API definition.
Error Response Example
{
"jsonrpc": "2.0",
"id": 3,
"error": {
"code": 404,
"message": "Tool not found"
}
}
38.1. MCP components#
MCP (Model Context Protocol) has a modular architecture built around three main components: the Host, Client, and Server. Each has a distinct role for enabling secure and structured communication between AI applications and external resources or tools. [1] [2] [3]
Host
The Host is the user-facing AI application or environment, such as Claude Desktop, an AI-powered IDE, or a custom agent application. Its responsibilities include managing user interactions, orchestrating the flow between LLM processing and tool calls, initiating client-server connections, and enforcing security boundaries. The Host coordinates the entire protocol lifecycle and ensures the user experience remains seamless. [4] [3] [1]. See mcp/github for hosts such as VSCode.
Client
The Client resides within the Host application and is responsible for implementing the MCP protocol and handling one-to-one communication with a specific MCP Server. It manages session states, negotiates capabilities, handles secure data exchange, and routes requests or responses between the Host and Server. Each Client connects to a single Server, and Hosts can spawn multiple Clients to interface with multiple Servers. [5] [6] [3]
Server
The Server is an independent process, service, or API that exposes functionality, data, or resources to AI models via the MCP protocol. Servers can provide tools (actions the AI can perform), resources (context or data), or prompts (reusable templates), and are responsible for processing incoming requests, executing external actions, and returning results to Clients. Servers work in isolation—focused on specific capabilities—and are designed to be simple, composable, and secure. [7] [3] [4] [1]
Additional Layers: Data and Transport
Data Layer: Handles JSON-RPC-based protocol messaging, including tool/resource/prompt definitions, session management, and notifications. [5]
Transport Layer: Manages how data is exchanged (e.g., via stdio for local or HTTP+SSE for remote), including connection, framing, and authentication. [4] [5]
This clear separation of labor ensures that AI Hosts focus on reasoning, Clients manage secure and stateful interactions, and Servers provide modular, reusable extensions to the AI’s capabilities. [3] [7]
38.2. A list of MCP servers#
A centralized, official source for discovering MCP servers is the MCP Registry, launched in 2025 as an open catalog and API dedicated to publicly available MCP servers. It acts like an app store for MCP servers, providing a single authoritative repository for server metadata, including endpoints, capabilities, and versions. [1] [2]
The MCP Registry is hosted at
registry.modelcontextprotocol.ioand is community-owned with contributions from major organizations like Anthropic, GitHub, and Microsoft. It supports federated discovery through public and private sub-registries, allowing curated marketplaces and enterprise-specific registries to build on top of the shared core metadata. [2] [4]Anyone can browse the registry via its API to list MCP servers with pagination and search functionality, or developers can publish new servers following the registry’s open API specification. The registry emphasizes trust and moderation, featuring community mechanisms for flagging and removing malicious or spammy entries to maintain ecosystem integrity. [4] [1]
See: https://registry.modelcontextprotocol.io
A huge list of MCP servers is here: https://mcpmarket.com/server
From the GitHub page there is also a list of servers: modelcontextprotocol/servers

Welcome to the late show. I'm your host, Stephen Colbear. Folks, it looked like
I don't know if you've seen I don't know if you see in the the newspapers today.
It looks like the government shutdown is coming to an end. Our long national
nightmare is different. At what how many days? 41 days so far. It is the longest
shutdown in US history. Democrats have been holding the line, demanding
Republicans compromise to keep Affordable Care Act subsidies available for
millions of Americans. Well, last night, eight Democratic senators voted with
Republicans to fund the government through January without any Affordable Care
Act guarantees. [Applause] So, yes. So, yes, yes, the shutdown may have been
long and painful for millions of Americans, but at least it achieved jack squat.
That is, and we know why Jack is squatting. But these Democratic defectors did
get one concession. Senate Majority Leader John Thun promised them a vote on the
ACA in December, cuz that's when people get down to serious work. December. You
work about six days and half of that is spent doing a mandatory office door
decorating contest. Welcome to accounting or should I say the Polar Express. Now
you got hot chocolate lot. No, no surprise. The vast majority of Democrats do
not want this. None of those eight Senate Democrats are up for re reelection
next year and two have announced they are retiring from the Senate. What a
disappointing way to end your career. Reminds me of when Journey released their
last single, We Stopped Believing, did they? I don't know. One of the Democrats
who crumbled like a granola bar in your backpack is New Hampshire Senator and
the Joker's proud aunt, Jean Shaheen. Shaheen was asked about her decision and
she said, "When I talk to my constituents in New Hampshire, you know what they
say to me? Uh, are we Vermont or the other one? Are we which one? One of us is
we're upside down us or are we upside down them?" She continued, "They say why
can't you all just work together to address the problems that are facing this
country? Cuz the country is being run by insane people. My constituents want to
know why we can't work with the methaddled chimps who broke into the cockpit and
are now flying the plane. Some of their ideas are reasonable, although
admittedly some are bananas. This weekend, while airports were in utter chaos
and thousands without food benefits across America, Trump showed sensitive
leadership and attended his second extravagant party at Mara Lago in a week.
[Applause] Come on, Mr. President. Read the room. I'm sorry. I forgot who I was
talking to. Have someone summarize the room for you. The party The party was co-
hosted by the conservative political action conference or spatchcock. The the
esteemed guests included far-right British politician Nigel Farage, disgraced
butter junkie Paulyine, and Hercules star Kevin Sorbo. I think I think it's
pretty incredible. Sorbo found the time considering production of Hercules
wrapped only 26 years ago. Guests fun show gave a Zenus. Guests were treated to
some entertainment including this opera singer. >> Okay, she has a lovely voice.
But does Mara Lago have a mandatory bare midrift policy? Tonight we're doing wet
t-shirt opera. Okay, then gentlemen, get out your singles cuz they're dancing
the G-string Nutcracker. I'm going to I'm going to tuck Mr. Washington I'm going
to tuck Mr. Washington right into the old sugar plums. Hey, it's fun. Speaking
of pure MAGA elegance, there were also two ladies in flag swimsuits doing
synchronized swimming to Lee Greenwood [Music] >> and I had to start again with
just my children and my wife. that I'm proud to be an American. >> You know,
hearing that song also makes me want to dive into the water, but only after I
first filled my pockets with rocks. Not to nitpick, but they're only two of
them. Two. Two is really the bare minimum for for synchronized swimming. And I'm
told we have Kevin Sorbo's review. >> Disappointed. >> He's not happy. >> He's
not happy. He did not like it. This party makes it seem like it's really easy to
get into Mara Lago as long as your talent shows some skin and is vaguely
patriotic. Thank you, swimmer ladies. Now, please welcome Tina, who's going to
take off her top and eat a flag. A flag cake? No, just the flag. She's going to
eat the flag. Of course, after uh two ladies same time swimming, Trump's second
favorite sport would be football. And over the weekend, we learned Trump wants
the Washington Commander new DC stadium named for him. But that's no, that's not
that's not how any of this works. You're you're name you name things after
people once they're out of office. The president doesn't just ask for it. Ex
except when Reagan said this, >> Mr. the garbage of give big Ron Ron an airport.
Look how happy the people are. People are so happy. Now Trump Trump doesn't just
want this. He is pushing to make it happen. The White House says there have been
back channel communications with the commander ownership group to express
Trump's desire to have the stadium bear his name and his press secretary
basically confirmed it saying that would be a beautiful name. Yes, it's a very
No. Hey, no, it is it would be beautiful. After all, everyone knows that Trump
is a lovely portmanto of the words tremendous and dump. Yesterday, maybe we
should have done the animation. Maybe we should have done the animation. Who
cares? Yesterday, Trump went to go see a commander game in person, and the fans
were not happy to see him. [Music] [Applause] Fun fact for the folks at home,
for the broadcast of our show, our editor, Brian, had to go through that clip uh
frame by frame and blur out every single uh middle finger that was raised. How
are How are you feeling after all that work, Brian? Okay. All right. Just one
more. Thank you. That's enough. That's good. A long time. >> Okay. Just Just one
more. You'll have to blur. >> Now, a little booing from a crowd didn't stop
Trump from joining the announcers and trying his best call play. >> Well, let's
see what happens here. This is a big >> big down. All right. They're they're
calling a timeout here. President Trump. They're trying to regroup. It's a
fourth and goal. Oh, no, excuse me. fourth and short. >> But you can't equate
sports with life. You know, you have the triumph and you have the the problems
and you got to get through the problems to hit the triumphs. And you can never
quit. You can never give up. Was a little rough. Was a little rough. That marks
the first time the guys in the booth got brain damage. >> Now, yeah. more
evidence of Trump's uh troubling spiral into last week. You'll recall the Trump
held a presser where one of the attendees passed out uh while he was talking.
Guy was fine. Uh and it turns out he wasn't the only one catching a little shut
eyee. According to video analysis by the Washington Post, at that same meeting,
the president spent nearly 20 minutes apparently battling to keep his eyes open.
Great. Our president is an old man who can't stay awake like that classic folk
tale, Rip Vancle. Here's just we have this, right? We have this. Okay. Rip
Vancle. Here's just some of the commander-in-chief dozing off. What about the
people in urban areas who live in food deserts and are suffering from obesity?
President Trump has also instructed us to address and and the root causes of
chronic disease. In the meantime, there's nothing more important than we can do
than lower this price. >> Do you know how hard it is to fall asleep to RFK Jr.'s
voice? >> That is not the easiest. Not the most Ooh. Ooh. Bedtime. Setting my
white noise machine to handful of gravel and a neutral bullet. Photographers on
the scene in the Oval Office there nab some pretty good shots of Trump snooze.
And uh there's this one. Uh he's out. Uh this one. Bye-bye. And my favorite,
this one, where in fairness, in fairness, he looks less asleep and more just
miserable like he's watching Eric in his High School Musical. Oh god. When When
the hell does the fiddler jump off the stupid roof? Sunrise, sunset, sunrise,
sunset. If I were a rich man. Yeah. Madame Madam, [Applause] a cool vata. Come
on. We got a great show for you tonight. My guest is more when we come back.
Science. Come on. [Applause] [Music] [Applause] [Music] Yeah.

38.5. Setting up a local MCP Server#
Python SDK with examples: modelcontextprotocol/python-sdk
To try this out follow the instructions at https://pypi.org/project/mcp
Let’s use Claude Code to call a MCP server that we run on our local machine. The detailed steps you can use on your laptop are as follows:
Set up the env from the CLI:
conda create -n mcp python=3.13
conda activate mcp
pip install uv
pip install "mcp[cli]"
Now, create an initial project by using the following instantiation:
uv init demo
cd demo
Copy the code from here into a file called basic_tools.py in the demo folder: modelcontextprotocol/python-sdk
The file looks like this:
from mcp.server.fastmcp import FastMCP
mcp = FastMCP(name="Tool Example")
@mcp.tool()
def sum(a: int, b: int) -> int:
"""Add two numbers together."""
return a + b
@mcp.tool()
def get_weather(city: str, unit: str = "celsius") -> str:
"""Get weather for a city."""
# This would normally call a weather API
return f"Weather in {city}: 22degrees{unit[0].upper()}"
The mcp.tool decorator in Python is all you need to specify a function as a tool.
Now run the MCP server:
uv run mcp install basic_tools.py
Now, everything is ready for use by Claude Desktop.
38.6. Use Claude Desktop as MCP Host & Client#
Install Claude Desktop by downloading it from here: https://www.claude.com/download
Then run it!
First, go to User -> Settings
Image('NLP_images/claude_chat.png', height=600)
Then choose Developer to see the running MCP servers.
Image('NLP_images/claude_dev_settings.png', width=600)
Then open New Chat to get the following:
Image('NLP_images/claude_chat_interface.png', width=600)
See that the tool T is used when apt:
Image('NLP_images/claude_tool_use.png', width=600)
Take a look at the other servers that may show you other usage patterns: modelcontextprotocol/python-sdk
38.7. Installing the MCP Server for using the File System#
The approach to doing this is to use the filesystem MCP server from here: modelcontextprotocol/servers
Copy the NPX config into the claude_desktop_config.json file. This file (on a Mac) is in this folder: /Users/sanjivda/Library/Application Support/Claude
{
"mcpServers": {
"filesystem": {
"command": "npx",
"args": [
"-y",
"@modelcontextprotocol/server-filesystem",
"/Users/username/Desktop",
"/path/to/other/allowed/dir"
]
}
}
}
Update the paths to the folder above to the actual local folders you want to give access to.
Then restart Claude Desktop and you can issue commands to add files, delete files, etc.
Image('NLP_images/claude_fileserver.png', width=600)
