Implementation Reference

• main.py:6-16 (handler)

  The handler function that executes the 'add' tool logic. Takes two integers (a, b) as input and returns their sum. Type hints and docstring provide the schema for input/output validation.

  def add(a: int, b: int) -> int:
      """Add two integers together.
      
      Args:
          a: First integer
          b: Second integer
          
      Returns:
          The sum of a and b
      """
      return a + b

• main.py:5-5 (registration)

  The @mcp.tool decorator registers the 'add' function as an MCP tool with the FastMCP server instance.

  @mcp.tool

• main.py:6-15 (schema)

  Input/output schema defined through Python type hints (a: int, b: int -> int) and comprehensive docstring documenting the parameters and return value.

  def add(a: int, b: int) -> int:
      """Add two integers together.
      
      Args:
          a: First integer
          b: Second integer
          
      Returns:
          The sum of a and b
