Build a Python MCP Client to Test Servers From Your Terminal

Building an MCP client in Python can be a good option when you’re coding MCP servers and want a quick way to test them. In this step-by-step project, you’ll build a minimal MCP client for the command line. It’ll be able to connect to an MCP server through the standard input/output (stdio) transport, list the server’s capabilities, and use the server’s tools to feed an AI-powered chat.

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

  • You can build an MCP client app for the command line using the MCP Python SDK and argparse.
  • You can list a server’s capabilities by calling .list_tools(), .list_prompts(), and .list_resources() on a ClientSession instance.
  • You can use the OpenAI Python SDK to integrate
