Agentic Mermaid MCP Server

Beautiful diagrams, made with your agent. Agentic Mermaid is an open-source Mermaid toolkit for people who want AI agents to create diagrams that look finished: SVG and PNG renders, ASCII and Unicode for review, deterministic layout, and Style + Palette controls for brand colors, typography, strokes, fills, and backdrops.

People connecting this server to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.
