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"
