MCP Server Chart – An open-source visualization chart MCP by AntV from Ant Group

What is MCP Server Chart?

MCP Server Chart is a visual chart generation tool developed by the AntV team at Ant Group. Built on the Model Context Protocol (MCP), the tool supports the creation of over 25 types of visualizations, including common statistical charts (such as line charts, bar charts, and pie charts), relationship-based diagrams (like organizational charts, mind maps, and network graphs), as well as annotated and path-based maps. With simple text input, users can quickly generate charts without the need for complex operations. It supports integration with various client platforms like Cherry Studio, Claude Desktop, and more, and provides both SSE and Streamable transport protocols for seamless platform integration.

Key Features of MCP Server Chart

Rich Chart Types: Supports more than 25 visualization types, including standard statistical charts (line, bar, pie), relationship graphs (organizational, mind maps, network), and map visualizations (annotated and path maps).
User-Friendly: Users can create charts with simple text input, avoiding complex setup and significantly lowering the barrier to data visualization.
Multi-Client Access: Compatible with clients like Cherry Studio, Claude Desktop, VSCode, and more, allowing use across different development environments.
Flexible Deployment: Offers both public and private deployment options. Through the VIS_REQUEST_SERVER environment variable, users can configure custom chart-generation servers.
Generation Record Tracking: Allows users to view their chart generation history by creating a personal identifier via an Alipay Mini Program—enabling convenient management and traceability.

Technical Principles of MCP Server Chart

Built on MCP Protocol: MCP Server Chart adheres to the Model Context Protocol (MCP), which defines how tools are structured and enables models to parse parameters directly, facilitating efficient chart generation.
Powered by GPT-Vis Visualization Library: Utilizes the GPT-Vis component library tailored for AI consumption, supporting over 25 chart types. Combined with AntV’s robust visualization solutions, it ensures high-quality and diverse chart outputs.
Server-Side Rendering (SSR): Leverages the SSR capabilities of GPT-Vis, as well as AntV’s G2 and G6, to render charts as static images. Compared to front-end UI components, static images offer better cross-platform compatibility and performance.
Static Chart Generation Tool: Encapsulates GPT-Vis SSR as a static chart generation service, built using Node.js internally at Ant Group. It provides external access for users to generate static charts via simple configurations and calls.
Multi-Protocol Transmission: Supports various transmission protocols such as stdio, SSE, and streamable, allowing flexible integration depending on user scenarios and improving system extensibility.
