Implementation Reference

• src/gdb_multiarch_mcp/gdb_interface.py:723-745 (handler)

  The handler implementation for the `gdb_select_thread` tool, which calls `execute_command` with `-thread-select` using the GDB/MI protocol.

  def select_thread(self, thread_id: int) -> dict[str, Any]:
      """
      Select a specific thread to make it the current thread.
  
      Args:
          thread_id: Thread ID to select
  
      Returns:
          Dict with status and selected thread information
      """
      result = self.execute_command(f"-thread-select {thread_id}")
  
      if result["status"] == "error":
          return result
  
      mi_result = self._extract_mi_result(result) or {}
  
      return {
          "status": "success",
          "thread_id": thread_id,
          "new_thread_id": mi_result.get("new-thread-id"),
          "frame": mi_result.get("frame"),
      }

• src/gdb_multiarch_mcp/server.py:251-255 (registration)

  Tool registration for `gdb_select_thread` in `src/gdb_multiarch_mcp/server.py`.

  Tool(
      name="gdb_select_thread",
      description="Select a specific thread.",
      inputSchema=ThreadSelectArgs.model_json_schema(),
  ),

• src/gdb_multiarch_mcp/server.py:464-466 (handler)

  The execution path in the server loop that calls `session.select_thread`.

  elif name == "gdb_select_thread":
      a = ThreadSelectArgs(**arguments)
      result = session.select_thread(thread_id=a.thread_id)
