What it is

A Model Context Protocol server for generating charts using AntV. It supports chart generation and data analysis via MCP tools.

How it works

The project exposes an MCP server that can generate multiple chart types (26+), allowing clients to request chart generation via MCP tools and receive chart outputs. It supports SSE and streamable transports, with an HTTP-based private deployment path via VIS_REQUEST_SERVER and tool filtering via DISABLED_TOOLS.

Getting started

Install dependencies:

npm install

Build the server:

npm run build

Start the MCP server:

npm run start

Start with SSE transport:

node build/index.js -t sse

Start with Streamable transport:

node build/index.js -t streamable

Configure via environment or mcpServers config in your app, examples show VIS_REQUEST_SERVER, SERVICE_ID, and DISABLED_TOOLS usage.
