Branded chart rendering for AI agents — hosted MCP server, zero setup
Overview
ChartOne MCP
Give your AI agent the ability to render branded charts and return a persistent hosted URL — embed in markdown READMEs, emails, Slack messages, and docs without copy-pasting screenshots.
Tools
- render_chart — Render a chart from data with a specified type and theme. Returns an inline image + hosted URL.
- suggest_chart — Describe your data intent in plain language; ChartOne's AI picks the best chart type and theme.
Anonymous mode
Works without an API key — charts render watermarked with a 7-day URL. Request an API key at chartone.dev for higher quota and no watermark.
Example prompts
- "Add a chart of our Q4 benchmark results to the README"
- "Make a bar chart of monthly signups and give me the URL to embed in the email"
- "Visualize this revenue data and suggest the best chart type"
