Interactive Chart Configuration Schema Validation

A Model Context Protocol server for generating charts using AntV, This is a TypeScript-based MCP server that provides chart generation capabilities. It allows you to create various types of charts through MCP tools.

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 others: Tighter validation than generic JSON schema validators because it understands AntV-specific constraints; faster feedback than discovering errors during rendering.

via “zod-based schema validation for chart inputs”

** - Generate visual charts using [ECharts](https://echarts.apache.org) with AI MCP dynamically, used for chart generation and data analysis.

Unique: Uses Zod schemas defined in src/utils/schema.ts as the single source of truth for chart input validation, integrated directly into MCP tool definitions. Validation happens at the protocol layer before tool execution, preventing invalid data from reaching the rendering engine.

vs others: More robust than regex-based validation because Zod provides structural validation with type inference; catches more error classes (type mismatches, array length violations, numeric ranges) than simple presence checks

via “chart configuration schema introspection and validation”

** - This server offers a wide variety of chart types with comprehensive Zod schema validation for type-safe chart configuration.

Unique: Uses Zod's declarative schema system to provide both machine-readable schema introspection and human-readable validation errors, enabling clients to understand and validate chart configurations without parsing documentation

vs others: Provides better validation feedback than JSON Schema validators because Zod errors include context about what went wrong and how to fix it, and enables stronger type safety than runtime-only validation
