- Developers embedding charts where JavaScript cannot run
- Worth noticing
- The page documents an MCP server with chart_url and render_chart tools, alongside a free GET endpoint that needs no key.
Field notes
The examples use Chart.js JSON and include presets for KPI and ranking displays, with options such as a previous value, prefix, or suffix. The page gives separate cURL, Node, and Claude Code setup paths; its Node example distinguishes generating a signed URL from returning PNG bytes. The sample charts are explicitly described as drawn from made-up data.
