My UV MCP Server

This is a simple Model Context Protocol (MCP) server built using Python and the uv package manager.
It demonstrates creating a basic MCP server with tools and connecting it to Claude Desktop.

Quick Start

Follow these steps to set up and run the MCP server:

1. Create the MCP Server

Create a file server.py with the following code:

from mcp.server.fastmcp import FastMCP

mcp = FastMCP("My UV MCP Server")

@mcp.tool()
def greet(name: str) -> str:
    """Return a greeting message."""
    return f"Hello, {name}! 👋"

if __name__ == "__main__":
    mcp.run()

    A3.6/5.0

    Disambiguation5/5

    With only one tool, there is no possibility of ambiguity or overlap between tools. The tool 'add_numbers' has a single, clearly defined purpose that cannot be confused with any other tool in this set.

    Naming Consistency5/5

    The single tool name 'add_numbers' follows a clear verb_noun pattern, and with only one tool, there is no inconsistency to evaluate. The naming is straightforward and predictable in isolation.

    Tool Count2/5

    A single tool is too few for most practical server purposes, as it severely limits functionality and scope. This feels thin and inadequate for handling any meaningful domain beyond a trivial operation, indicating a poor fit for typical MCP server use cases.

    Completeness1/5

    The server's purpose is unclear from the single tool, making it impossible to assess coverage meaningfully. With only a basic arithmetic operation, there are significant gaps in any plausible domain, rendering the tool surface severely incomplete for practical agent workflows.
