| Tool | Description |
|---|---|
| render_chart | Render and validate a chart config, store it for 10 minutes, and return a public image URL. A fetched image may remain cached for up to 1 hour. Authenticated calls use the account's render allowance. |
| save_chart | Save and publish a chart config to permanent public Image and Embed URLs, and return Edit and Studio management URLs. Requires authentication and uses saved-chart storage. |
| validate_chart | Check a chart config against the current schema without creating an image. Use when validation itself is requested or while debugging. |
| list_themes | List all available chart themes with guidance on where each works best. |
| list_marks | List all available mark types with their specific properties and defaults. |
| get_examples | Get current, ready-to-use chart configs that demonstrate preferred semantic patterns, including built-in labels. Optionally filter by mark type. |
