THEN Replace the usage of python-sdk's FastMCP with FastMCP 2.0 from gofastmcp.com, which correctly handles image returns. Install via `pip install fastmcp` and update imports from `mcp.server.fastmcp` to `fastmcp`.

from fastmcp import FastMCP, Image
from PIL import Image as PILImage

mcp = FastMCP("My App")

@mcp.tool()
def create_thumbnail(image_path: str) -> Image:
    img = PILImage.open(image_path)
    img.thumbnail((100, 100))
    return Image(data=img.tobytes(), format="png")
