Implementation Reference

• mcp_jira/tools/echo.py:6-28 (handler)

  Core handler function implementing the echo tool logic: echoes input text with optional upper/lower case transformation and returns MCP TextContent.

  def echo(text: str, transform: Optional[str] = None) -> types.TextContent:
      """
      Echo the input text back to the caller with optional case transformation.
      
      Args:
          text: The text to echo back
          transform: Optional case transformation ('upper' or 'lower')
          
      Returns:
          TextContent: The transformed text as MCP TextContent
      """
      if transform == "upper":
          result = text.upper()
      elif transform == "lower":
          result = text.lower()
      else:
          result = text
          
      return types.TextContent(
          type="text",
          text=result,
          format="text/plain"
      ) 

• mcp_jira/server/app.py:43-49 (registration)

  Registration of the 'echo' tool via @mcp_server.tool decorator. Includes a thin wrapper function that delegates to the core echo implementation.

  @mcp_server.tool(
      name="echo",
      description="Echo back the input text with optional case transformation",
  )
  def echo_tool(text: str, transform: Optional[str] = None) -> types.TextContent:
      """Wrapper around the echo tool implementation"""
      return echo(text, transform)
