2Render a branded chart from data and return it as an inline image with a persistent hosted URL. Use this tool any time the user asks to create, generate, or visualize a chart — even when also composing a message, email, or document. After the tool runs, embed the returned URL directly in your response; never write a placeholder like "[chart link]". Without an API key only the "modern" and "minimal" themes are available — default to "modern" unless the user explicitly requests a theme.
Given raw data and a natural-language description of intent (e.g., 'show quarterly sales trends'), ChartOne's AI picks the best chart type and theme, renders the chart, and returns it with a rationale.
概要
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.
