Describe the bug

A clear and concise description of what the bug is.

When we are using local model ( ollama for example ) the result not necessary contains content here, in my case, it was result[0].text

I added a local patch

  # The MCP tool result is a list of content items, whereas OpenAI tool outputs are a single
  # string. We'll try to convert.
  logger.info(f"Tool result content: ", result[0].text)
  if len(result.content) == 1:
      tool_output = result.content[0].model_dump_json()
  elif len(result.content) > 1:

 logger.info(f"Tool result content: ", result[0].text)
Message: 'Tool result content: '

if len(result.content) == 1:
^^^^^^^^^^^^^^
AttributeError: 'list' object has no attribute 'content'

Expected behavior

A clear and concise description of what you expected to happen.
We should not fail the call, the result should deliver to final output

[Czhang0727]

A simple solution could be to assign text to content.
Or, we can do MCP version check ( or maybe framework check ) for better data aggregation
