Data Visualization MCP Server

visualize_data

Transform complex data into visual insights using Vega-Lite specifications. Save data to a table, then generate clear, multi-dimensional visualizations for better understanding and analysis.

Instructions

A tool which allows you to produce a data visualization using the Vega-Lite grammar. When to use this tool:

  • At times, it will be advantageous to provide the user with a visual representation of some data, rather than just a textual representation.
  • This tool is particularly useful when the data is complex or has many dimensions, making it difficult to understand in a tabular format. It is not useful for singular data points. How to use this tool:
  • Prior to visualization, data must be saved to a named table using the save_data tool.
  • After saving the data, use this tool to visualize the data by providing the name of the table with the saved data and a Vega-Lite specification.

Input Schema
