What is Data Visualization MCP Server?
The Data Visualization MCP Server is an implementation of the Model Context Protocol (MCP) that allows Large Language Models (LLMs) to interact with data and create visualizations. It provides tools for saving data tables and visualizing them using Vega-Lite syntax.
How to use Data Visualization MCP Server?
To use the server, you need to add it to your claude_desktop_config.json file, specifying the command and arguments required to run the server. The server exposes two tools: save_data for storing data and visualize_data for generating visualizations from saved data using Vega-Lite specifications. The server can output visualizations as either text (Vega-Lite specification) or a base64 encoded PNG image.

FAQ from Data Visualization MCP Server
What is Vega-Lite?
What is Vega-Lite?
Vega-Lite is a high-level grammar for visual representation, providing a concise JSON syntax for creating interactive graphics.
How do I save data to the server?
How do I save data to the server?
Use the save_data tool, providing a name for the data table and an array of objects representing the data.
How do I visualize data?
How do I visualize data?
Use the visualize_data tool, providing the name of the saved data table and a JSON string representing the Vega-Lite specification for the desired visualization.
What output types are supported?
What output types are supported?
The server supports two output types: text, which returns the complete Vega-Lite specification with data, and png, which returns a base64 encoded PNG image of the visualization.
