Exposes chart creation as MCP tools that Claude and other MCP clients can invoke directly through the Model Context Protocol. The server implements the MCP tool-calling interface, allowing LLM agents to request chart generation by name and parameters without manual API orchestration. Uses TypeScript bindings to AntV's rendering engine, translating tool invocations into chart specifications that are rendered server-side.
Unique: Implements chart generation as first-class MCP tools rather than wrapping a REST API, enabling native LLM reasoning about visualization choices through the protocol's tool-calling semantics. Uses AntV's TypeScript API directly within the MCP server process, eliminating round-trip serialization overhead compared to HTTP-based chart services.
vs alternatives: Tighter integration with Claude and MCP-native agents than REST-based chart APIs (Plotly, Vega-Lite servers), with lower latency and direct tool-calling support; simpler than building custom Claude plugins for visualization.
Supports a comprehensive set of AntV chart types (bar, line, area, scatter, pie, heatmap, etc.) through a unified configuration schema. Each chart type accepts standardized data structures and configuration objects that map to AntV's G2 or G2Plot libraries. The server validates chart specifications against AntV's schema and renders them using the underlying graphics engine, handling coordinate systems, scales, and visual encodings automatically.
Unique: Leverages AntV's declarative grammar-of-graphics approach (G2/G2Plot) to unify chart specification across 20+ chart types, allowing a single configuration pattern to work across bars, lines, scatters, and more. Abstracts away coordinate system and scale management that would otherwise require type-specific code.
vs alternatives: More consistent and composable than Plotly's type-specific APIs; simpler declarative syntax than raw D3 while maintaining more flexibility than high-level libraries like Recharts.
Accepts raw or semi-structured data and applies transformations (filtering, grouping, aggregation) to prepare it for visualization. The server can perform operations like sum/average/count aggregations, pivot transformations, and data reshaping to match chart input requirements. Transformations are specified declaratively in the chart configuration, allowing the LLM to request data preparation without separate ETL steps.
Unique: Integrates data transformation directly into the chart specification layer rather than requiring separate ETL, allowing Claude to request 'show me sales by region' and have the server handle both aggregation and visualization in a single MCP call. Uses AntV's data transform API to apply transformations declaratively.
vs alternatives: Faster iteration than separate data pipeline + visualization tools; more integrated than calling pandas/dplyr separately then passing results to a chart library.
Renders charts to multiple output formats (SVG, PNG, PDF) and encodes them for transmission over MCP. The server uses AntV's canvas/SVG rendering backends to generate raster or vector outputs, then encodes results as base64 or file references for delivery to the MCP client. Supports configurable resolution, dimensions, and format-specific options (compression, quality).
Unique: Handles format conversion within the MCP server process, eliminating the need for external image processing tools or separate rendering services. Uses AntV's built-in rendering backends to produce both vector (SVG) and raster (PNG) outputs from the same specification.
vs alternatives: More integrated than calling external tools like ImageMagick or Puppeteer; supports multiple formats from a single API call unlike format-specific services.
Validates chart specifications against AntV's schema before rendering, catching configuration errors early and providing detailed error messages. The server implements schema validation using TypeScript type definitions and runtime checks, ensuring that chart configs match expected structure for the requested chart type. Validation includes type checking, required field verification, and constraint validation (e.g., valid color values, numeric ranges).
Unique: Implements compile-time (TypeScript) and runtime validation of chart specs, catching errors before expensive rendering operations. Uses AntV's type definitions to validate against the actual library's expectations rather than a separate schema.
vs alternatives: Tighter validation than generic JSON schema validators because it understands AntV-specific constraints; faster feedback than discovering errors during rendering.
Allows customization of chart appearance through theme and style specifications (colors, fonts, sizes, spacing). The server applies theme configurations to charts before rendering, supporting both predefined themes and custom style objects. Theming is applied at the AntV G2 level, affecting all visual elements (axes, legends, tooltips, data marks) consistently across chart types.
Unique: Applies theming at the AntV G2 engine level, ensuring consistent styling across all chart types and components (axes, legends, tooltips) from a single configuration. Supports both predefined themes and custom style objects without requiring CSS or DOM manipulation.
vs alternatives: More comprehensive than Plotly's limited theming options; simpler than D3 custom styling while maintaining more control than high-level libraries.
Provides fine-grained control over axes (labels, scales, ranges, formatting) and legends (positioning, grouping, filtering) to improve chart readability and data interpretation. The server accepts axis and legend specifications in the chart config, applying them through AntV's scale and legend APIs. Supports custom axis labels, logarithmic scales, date formatting, and legend filtering to highlight relevant data dimensions.
Unique: Exposes AntV's scale and legend APIs through the MCP interface, allowing Claude to request specific axis formatting (e.g., 'show axis as percentages') without manual configuration. Handles coordinate system and scale management automatically based on chart type.
vs alternatives: More flexible than Plotly's limited axis customization; simpler than raw D3 scale configuration while maintaining more control than Recharts.
Configures interactive elements (tooltips, hover effects, click handlers) that enhance chart usability in interactive contexts. The server accepts tooltip specifications (content, formatting, positioning) and applies them through AntV's interaction API. Supports custom tooltip templates, conditional visibility, and formatting of displayed values. Note: interactivity is limited in static exports but available in interactive rendering contexts.
Unique: Configures tooltips and interactions through AntV's declarative interaction API rather than imperative event handlers, allowing Claude to request 'show detailed info on hover' without writing JavaScript. Supports custom templates for rich tooltip content.
vs alternatives: More integrated than adding tooltips post-render; simpler than implementing custom D3 interactions while maintaining more flexibility than Recharts' limited tooltip options.

Establishes bidirectional communication between LLM clients (Claude Desktop, VS Code Copilot, Cursor IDE) and MongoDB instances through the Model Context Protocol using either stdio or HTTP transports. The server implements a four-layer architecture separating transport handling, server orchestration, tool execution, and external service integration, enabling seamless tool invocation without custom client-side integration code.
