Overview
What is Chartone?
Chartone is an MCP server that enables AI agents to render branded charts and return a persistent hosted URL for embedding in READMEs, emails, Slack messages, and docs without manual screenshots. It integrates with any MCP-compatible client and is designed for users who need programmatic chart generation.
How to use Chartone?
Use the render_chart tool to render a chart from data with a specified type and theme, or the suggest_chart tool to describe your data intent in plain language and let Chartone’s AI pick the best chart type and theme. Anonymous mode works without an API key; for higher quota and no watermark, request an API key at chartone.dev.
