Connects Claude or any MCP client to ChartOne's hosted rendering API. Exposes two tools: render_chart for explicit type and data control, and suggest_chart for intent-based generation where you describe what you want and it picks the chart type and theme. Every render returns both an inline image and a persistent hosted URL, which makes it clean for dropping charts into emails, Slack threads, or PDFs without worrying about attachment limits. Runs via npx with optional API key (anonymous mode adds a watermark). Paid tiers extend URL lifetime and remove branding. Good when you need presentable charts in conversational workflows without spinning up a local plotting stack.
