What is Data Visualization MCP Server?
This server is an implementation of the Model Context Protocol (MCP) designed to enable Large Language Models (LLMs) to visualize data. It provides tools to save data tables and create visualizations using Vega-Lite specifications.
How to use Data Visualization MCP Server?
To use this server, you need to add it to your claude_desktop_config.json file. Configure the command and args to point to the server's executable and specify the desired output type (png or text). The server provides two tools: save_data and visualize_data, which can be called by the LLM with appropriate inputs.

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 visualizations.
What is MCP?
What is MCP?
MCP stands for Model Context Protocol, a framework for enabling communication and interaction between different models and systems.
How do I specify the output type?
How do I specify the output type?
The output type is specified using the --output_type argument when running the server. It can be either png for a base64 encoded PNG image or text for the Vega-Lite JSON specification.
What is the save_data tool for?
What is the save_data tool for?
The save_data tool allows you to save a table of data aggregations to the server for later visualization. It takes a name and an array of data objects as input.
What is the visualize_data tool for?
What is the visualize_data tool for?
The visualize_data tool allows you to visualize a previously saved data table using a Vega-Lite specification. It takes the data name and the Vega-Lite JSON string as input.
