AntV Chart MCP
by AntV
Released

Summary
Official AntV MCP server that turns a description of your data into a rendered chart — 26 visualization types from bar and line to sankey, mind-map, fishbone and geographic maps.
Features
- 26 chart types including sankey, treemap, radar, violin and Venn diagrams
- Diagramming tools: flowchart, mind-map, fishbone and organization charts
- Geographic maps (district, pin and path) rendered via AMap
- No API key required — free default rendering service
- Private deployment via VIS_REQUEST_SERVER for confidential data
- DISABLED_TOOLS trims the tool list for smaller models
- stdio, SSE and streamable HTTP transports; Docker image available

Description
AntV Chart MCP is the official Model Context Protocol server from AntV, the data-visualization team at Ant Group whose G2, G6 and L7 libraries sit behind a large share of China's enterprise dashboards. It gives an assistant a vocabulary of charts rather than a drawing API: you describe the data and the question, and the server returns a rendered image.
The catalogue runs to 26 visualization types and covers considerably more than the usual bar/line/pie trio. Statistical charts include histogram, boxplot, violin, scatter, radar, funnel, treemap, sankey and Venn. Diagramming types — flowchart, mind-map, fishbone, organization chart and network graph — make it useful for structure as well as numbers. Geographic output (district-map, pin-map, path-map) is rendered through AMap and is therefore limited to China. A spreadsheet/pivot-table tool rounds out the set for tabular summaries.
Installation is a single npx -y @antv/mcp-server-chart, with a cmd /c variant on Windows and a Docker image for server deployments. Three environment variables cover the cases teams usually hit: VIS_REQUEST_SERVER repoints rendering at a private deployment when charts contain data that cannot leave your network, SERVICE_ID tags generation records for tracking, and DISABLED_TOOLS trims the tool list so a smaller model is not overwhelmed by 26 near-identical schemas. The server speaks stdio, SSE and streamable HTTP transports.
Written in TypeScript and MIT-licensed. No API key is required — the default public rendering service is free to use, which makes this one of the fastest MCP servers to get a useful result out of, though private deployment is the right call for confidential data.
