Agentic Mermaid

Agentic Mermaid renders, verifies, describes, and safely edits Mermaid diagrams for AI agents.

Agentic Mermaid gives agents structured tools to render Mermaid diagrams as SVG, PNG, or ASCII, verify diagram correctness, describe existing diagrams in plain language, and apply typed edit operations instead of regenerating a diagram from scratch. It covers twelve diagram families with deterministic layout and configurable style palettes, and it runs as either a hosted remote server or a local stdio server for larger inputs.
