MCP Data Visualizer

MCPOpen Source57.8

by isaacwasserman • Visualization & Charts

An MCP server that lets LLMs save tabular aggregations and produce Vega-Lite visualizations (text spec or PNG).

Example Use Cases

1
Save and reference named tables of aggregated data for later visualization workflows.
2
Generate Vega-Lite visualizations from saved datasets and receive either the full spec or a PNG image.
3
Integrate programmatic data visualization into Claude Desktop-based agent pipelines.

Description

This server exposes two MCP tools—save_data and visualize_data—so agents can store aggregated tables and render them with Vega-Lite. It can return the full Vega-Lite spec (with data) as text or produce a base64 PNG image for visual output. The server integrates with Claude Desktop and is designed to let language models programmatically create and retrieve visualizations from saved datasets.
