MCP HTTP Client Example

This is a basic example client demonstrating how to connect to Model Context Protocol (MCP) servers over HTTP, utilizing Server-Sent Events (SSE) for transport. It leverages the official MCP Python SDK to manage protocol communication and interactions with the server.

Features

• Establishes connections to MCP servers using SSE transport.
• Retrieves and lists available tools, resources, and prompts offered by the server.
• Implements proper connection lifecycle management using asynchronous context managers for efficient resource handling.

Requirements

• uv

Usage

To use the client, clone the repository and execute the main.py script, providing the server URL as an argument:

uv run -- main.py <server_url>

For instance:

uv run -- main.py http://localhost:8000/sse

The client will then connect to the specified MCP server, retrieve its capabilities, and display them in JSON format.
