ChartBytes

Overview

ChartBytes is a Model Context Protocol server that generates chart images in PNG and SVG formats for AI agents. It supports bar, horizontal bar, stacked, line, area, scatter, pie, and donut charts, letting any MCP-compatible AI assistant call ChartBytes tools directly during conversations and agent runs.

The server runs locally via Docker using the image ghcr.io/haswell119/chartbytes-mcp:1.0.2. It communicates over stdio and requires an API key for authentication. Version 1.0.2 is the current release.

ChartBytes is listed in the AI & Agents category on mcp.site and integrates with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others. If you maintain ChartBytes, you can claim this listing to verify ownership and keep information current.
