Image response from an MCP server

[stneng]

#1898 adds support for image outputs in functions; the existing fallback logic in MCP tools below is outdated.

openai-agents-python/src/agents/mcp/util.py

Lines 217 to 227 in ba55bbd

	# Fall back to regular text content processing
	# The MCP tool result is a list of content items, whereas OpenAI tool
	# outputs are a single string. We'll try to convert.
	if len(result.content) == 1:
	tool_output = result.content[0].model_dump_json()
	elif len(result.content) > 1:
	tool_results = [item.model_dump(mode="json") for item in result.content]
	tool_output = json.dumps(tool_results)
	else:
	# Empty content is a valid result (e.g., "no results found")
	tool_output = "[]"

Resolves #2148 and https://community.openai.com/t/image-response-from-an-mcp-server-with-agents-sdk/1269441

Thanks for sending this. Indeed, this could work well now. I will do thorough testing early next year.
