Implementation Reference

• server.py:13-16 (registration)

  The sum tool is registered using the @mcp.tool() decorator, which exposes the function as an MCP tool.

  @mcp.tool()
  def sum(a: int, b: int) -> int:
      """Suma dos números."""
      return a + b

• server.py:14-16 (handler)

  The sum handler function that takes two integer parameters (a, b) and returns their sum. The function signature also serves as the schema definition.

  def sum(a: int, b: int) -> int:
      """Suma dos números."""
      return a + b
