Overview
A Model Context Protocol (MCP) server implementation that provides the LLM an interface for visualizing data using Vega-Lite syntax.
Components
Tools
The server offers two core tools:
- save_data
- Save a table of data agregations to the server for later visualization
- Input:
- name (string): Name of the data table to be saved
- data (array): Array of objects representing the data table
- Returns: success message
- visualize_data
- Visualize a table of data using Vega-Lite syntax
- Input:
- data_name (string): Name of the data table to be visualized
- vegalite_specification (string): JSON string representing the Vega-Lite specification
- Returns: If the --output_type is set to text, returns a success message with an additional artifact key containing the complete Vega-Lite specification with data. If the --output_type is set to png, returns a base64 encoded PNG image of the visualization using the MPC ImageContent container.
