mcp-mermaid and diagram-master
These are **competitors** — both generate visual diagrams through MCP, but A produces Mermaid's text-based diagram syntax while B integrates with Draw.io's proprietary format, requiring users to choose between declarative diagram-as-code or interactive graphical editing.
