download_chart
Download a chart image to a local file
LABSCO SUMMARY
The gap between having the numbers and having a picture of them is one call wide.
generate_chart takes the pieces you would otherwise assemble by hand — type, labels, datasets, options, title — and download_chart takes a config and an output path and writes the image where you asked for it. Nothing is configured and nothing is authenticated, so the whole surface is those two calls plus the data you arrived with.
What it is
A two-tool server over QuickChart: one builds a chart from a type, labels, datasets and options, the other downloads a chart image to a local file.
What you get
- A chart built from a chart type, its labels, one or more datasets, a title and an options object
- The rendered image written to a path you name, so it can be attached or committed rather than looked at once
Requirements
The data itself — labels and datasets — and, for the download tool, a writable output path. Nothing is authenticated: the server declares no environment variables.
Setup effort
One command — npx -y @gongrzhe/quickchart-mcp-server
USE CASES
01
Showing a number as a picture inside the conversation
Hand over the chart type, the labels and the datasets and get the chart back where the discussion is happening, rather than exporting the numbers to a spreadsheet to look at them.
02
Getting the chart into the document
Once the chart looks right, write the image to a path so it can be committed alongside the report that refers to it instead of being regenerated by whoever opens the file next.
