ChartPNG

Overview

ChartPNG is a Model Context Protocol server that renders Chart.js charts as PNG images, generating either shareable image URLs or the PNG files themselves. By exposing chart rendering as callable MCP tools, it lets AI assistants create visualizations without manual context switching between applications.

The server runs locally via the npm package @chartpng/mcp, which communicates with your MCP client over stdio. It requires an API Key for authentication and is currently at release v0.2.0. Learn more at https://chartpng.dev/docs.

ChartPNG appears in the Development category on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain ChartPNG, claim this listing to verify ownership and keep information up to date.
