I tried passing in the preferred-frame-size as metadata from python sdk's create_ui_resource as shown below
@mcp.tool
def some_ui_resource():
"""plot a dataframe"""
df = fetch_a_dataframe()
axes = df.plot()
#convert matplotlib plot to base64 string
import io
import base64
buf = io.BytesIO()
fig = axes.get_figure()
fig.savefig(buf, format='png')
buf.seek(0)
plot_data = base64.b64encode(buf.read()).decode('utf-8')
buf.close()
return create_ui_resource({
"uri": f"ui://some/ui/path",
"uiMetadata": {
"preferred-frame-size": [800, 600],
},
"content": {
"type": "rawHtml",
"htmlString": f"""
<img src="data:image/jpeg;base64,{plot_data}" alt="plot"/>
"""
},
"encoding": "text"
})I tried a model_dump of the created resource object and seems like the metadata is null.
{
"type": "resource",
"resource": {
"uri": "ui://some/uipath",
"mimeType": "text/html",
"meta": null,
"text": "\n <img src=\"data:image/jpeg;base64,some_data_here\" alt=\"plot\"/>\n "
},
"annotations": null,
"meta": null
}is this a missing feature in python sdk?
