Overview

szum renders chart images from JSON configs. One URL in, one PNG or SVG out. No JavaScript runtime, no client-side rendering, no dependencies. MCP Tools:

render_chart – render a config to a chart image URL

validate_chart – validate a config against the schema

generate_signed_url – Generate a signed URL for embedding charts in emails and tags (Pro)

list_themes – browse available themes

list_marks – list mark types and their properties

get_examples – get example chart configs

Why use szum from an AI agent? Plain JSON input with obvious field names. Deterministic output – same config, same image every time. Charts work anywhere images work: emails, PDFs, Slack, Notion, docs. 6 themes, 10 marks, PNG and SVG output.
