Testing MCP Servers With a Python MCP Client Rodrigo Girão Serrão 01:11

Building an MCP client in Python is a great way to test MCP servers directly from your terminal. In this video course, you’ll build a minimal MCP client for the command line. It can connect to an MCP server through the standard input/output (stdio) transport, list the server’s capabilities, and interact with the server’s tools, prompts, and resources directly and deterministically.

By the end of this video course, you’ll understand that:

You can build an MCP client app for the command line using the MCP Python SDK.
You can connect a client to an MCP server through the stdio transport and point it at any server from the command line.
You can list a server’s capabilities by calling .list_tools(), .list_prompts(), and .list_resources() on a ClientSession instance.
You can call tools, get prompts, and fetch resources from an MCP server through dedicated CLI subcommands.

Next, you’ll move through setup, client structure, server connection, and capability discovery to test MCP servers from your terminal.

00:00 Hello there, and welcome to this Real Python video course on Testing MCP Servers With a Python MCP Client. My name is Rodrigo, and I’ll be the one taking you on this journey. What are the main goals for this course?

00:14 What are you going to do? You’re going to understand what’s an MCP client, and you’re going to write a functional MCP client. So this will be a very practical course.

00:24 You’ll get your hands dirty and write a reasonable amount of code. As you do so, you’re going to write an MCP client that connects to an MCP server to do three things.

00:36 You’re going to get prompts from the server, you’re going to fetch resources from the server, and you’re going to call tools from the server. Now, if this sounds like something that’s interesting to you, and if you’re interested in understanding better how MCP servers work and how MCP clients work naturally, then you’re in the right course.

00:58 Join me for the next lesson where you’ll understand what an MCP client is and how that fits into the context of MCP servers and also the typical LLM-based agent.
