Implementation Reference

• main.py:31-42 (handler)

  The multiply tool handler implementation, decorated with @mcp.tool to register it as an MCP tool. Takes two integer parameters (a and b) and returns their product. The function includes comprehensive docstring documentation for the tool schema.

  @mcp.tool
  def multiply(a: int, b: int) -> int:
      """Multiply two integers together.
      
      Args:
          a: First integer
          b: Second integer
          
      Returns:
          The product of a and b
      """
      return a * b

• main.py:31-42 (registration)

  Registration of the multiply tool using FastMCP's @mcp.tool decorator on line 31. This decorator automatically registers the function as an MCP tool with its schema derived from the function signature and docstring.

  @mcp.tool
  def multiply(a: int, b: int) -> int:
      """Multiply two integers together.
      
      Args:
          a: First integer
          b: Second integer
          
      Returns:
          The product of a and b
      """
      return a * b

• main.py:32-41 (schema)

  Schema definition for the multiply tool: accepts two integer parameters (a and b) and returns an integer. The type hints and docstring define the input/output schema for MCP tool validation.

  def multiply(a: int, b: int) -> int:
      """Multiply two integers together.
      
      Args:
          a: First integer
          b: Second integer
          
      Returns:
          The product of a and b
      """
