ChartAnt is a remote MCP server that gives your AI assistant 51 tools to draw charts, diagrams and maps as real PNG images with their own link, ready for email, Slack, slides or a README. - 40+ chart and diagram types: line, bar, column, pie, area, scatter, funnel, sankey, treemap, waterfall, gantt, heatmap, KPI cards, dashboards, flowcharts, mind maps, org charts and more. - Maps of every country: world maps, the states, provinces or regions of any country, and pin maps from coordinates. Region names in 20+ languages, with "did you mean" hints for names that don't match. - Charts that stay updated: sign in once and your assistant can save a chart at a fixed link. Later, say "add 10% to this month's sales" and the image at the same link updates. Copies can go to Slack, Teams, Discord or email on every change or on a schedule. - Nothing to install and no API key: paste the URL into Claude, ChatGPT, Cursor, VS Code, Windsurf or n8n. - EU-hosted. Chart data is used only to draw the image and is never logged.

Reliable datasets from the unreliable web Tell Jsonify the data you need in plain words. Jason, its AI data engineer, picks the sources, builds the pipeline and checks every row.

You pay per row, and the first 100 rows a month are free. Collect web data, manage pipelines, query datasets, and explore dashboards with Jsonify. Connect using OAuth.
