Sample

This is a Python sample for an MCP Server

Here's what the calculator portion looks like:

@mcp.tool()
def add(a: float, b: float) -> float:
    """Add two numbers together and return the result."""
    return a + b

@mcp.tool()
def subtract(a: float, b: float) -> float:
    """Subtract b from a and return the result."""
    return a - b

@mcp.tool()
def multiply(a: float, b: float) -> float:
    """Multiply two numbers together and return the result."""
    return a * b

@mcp.tool()
def divide(a: float, b: float) -> float:
    """
    Divide a by b and return the result.
    
    Raises:
        ValueError: If b is zero
    """
    if b == 0:
        raise ValueError("Cannot divide by zero")
    return a / b

Install
