Data Visualization Server

MCPOpen Source19.5

by Mavline • Visualization & Charts

An MCP server that lets LLM agents save tabular aggregation data and generate Vega-Lite visualizations, returning either a Vega-Lite spec or a PNG image.

Example Use Cases

1
Persist aggregated tabular results on a server for later visualization or analysis.
2
Convert stored data into Vega-Lite visualizations programmatically and retrieve the full spec for inspection or embedding.
3
Produce PNG visual artifacts from Vega-Lite specs (MPC ImageContent) for reporting, display, or downstream processing.

Description

This MCP server exposes two tools for agents: save_data to store named tables of aggregated data, and visualize_data to render those tables using a Vega-Lite specification. It can return the complete Vega-Lite JSON (when output_type is text) or a base64 PNG image packaged in an MPC ImageContent container (when output_type is png). The project includes usage notes for integration with Claude Desktop and is useful for automating visualization generation from agent workflows.
