Implementation Reference

• src/frida_game_hacking_mcp/server.py:1732-1754 (handler)

  The handler function for the 'remove_breakpoint' tool. It checks if a breakpoint exists at the given address in the session state, unloads the associated Frida script, removes it from the breakpoints dictionary, and returns success or error status.

  def remove_breakpoint(address: str) -> Dict[str, Any]:
      """
      Remove a breakpoint.
      
      Args:
          address: Address of breakpoint to remove
      
      Returns:
          Removal status.
      """
      global _session
      
      if address not in _session.breakpoints:
          return {"error": f"No breakpoint at {address}"}
      
      try:
          _session.breakpoints[address].unload()
          del _session.breakpoints[address]
          return {"success": True, "address": address}
      
      except Exception as e:
          return {"error": f"Failed to remove breakpoint: {str(e)}"}

  The FridaSession class manages session state including a 'breakpoints' dictionary that stores active breakpoint scripts, used by remove_breakpoint to track and remove breakpoints.
