A potential mistake in the process_query function of the MCP client.

[pyaf]

The anthropic API says that messages of content type tool_use can have only following attributes:

Documentation Link

The MCP client's process_query function tried to check if there is a attribute text in a content block of type == tool_use - which as per the API documentation will not be the case.

quickstart-resources/mcp-client-python/client.py

Lines 88 to 92 in dfc9247

	if hasattr(content, 'text') and content.text:
	messages.append({
	"role": "assistant",
	"content": content.text
	})

---

While API may respond with an array of content blocks, maybe one with type = text, and then the next one with type = tool_use but a content of type tool_use will never have an attribute text.

Let me know if I'm missing something here. If you agree with this, I'd like to fix this.
