• server.py:78-89 (handler)

  The main handler function for the 'write_clipboard' MCP tool. It uses subprocess to call 'pbcopy' on macOS to write the provided text to the clipboard, decorated with @mcp.tool() for automatic registration and schema generation.

  @mcp.tool()
  def write_clipboard(text: str) -> str:
      """Write the given text to the clipboard (macOS). Uses `pbcopy`."""
      try:
          completed = subprocess.run([
              "bash", "-lc", "pbcopy"
          ], input=text, text=True, capture_output=True)
          if completed.returncode != 0:
              return f"❌ Failed to write clipboard (pbcopy exited {completed.returncode})."
          return "✅ Clipboard updated"
      except Exception as e:
          return f"❌ Error writing clipboard: {str(e)}"
