Microcharts MCP Server

Word-sized charts for React - zero runtime dependencies, ~2–7 kB interactive · ~1–4 kB static, accessible by default, and server-component safe. It runs locally over stdio via the published package.

People who work with accessible, chart and charts and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Microcharts

Claude Code

claude mcp add ganapativs-microcharts -- npx -y @microcharts/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "ganapativs-microcharts": {
      "command": "npx",
      "args": [
        "-y",
        "@microcharts/mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

license MIT - declared in the repository

npm package @microcharts/mcp - the @microcharts scope differs from the repo owner (ganapativs); confirm it's the project's official package

registry namespace io.github.ganapativs is GitHub-verified and matches the repo owner
