mcp-vegalite-server is a Model Context Protocol (MCP) server that provides an interface for generating data visualizations from fetched data using the Vega-Lite format and renderer. It is designed to allow large language models (LLMs) or other clients to interactively save data tables and create visualizations via Vega-Lite specifications.
save_data: Save a table of data aggregations to the server for later visualization.
name (string), data (array of objects)visualize_data: Visualize a saved data table using a Vega-Lite specification.
data_name (string), vegalite_specification (JSON string)--output_type is set to text, returns a success message and the complete Vega-Lite specification with data.--output_type is set to png, returns a base64 encoded PNG image of the visualization.No pricing information is provided; the project is open source on GitHub.
