A side-by-side look at the Mermaid MCP and Claude Mermaid MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Mermaid MCP for data visualization work; choose Claude Mermaid for data visualization over a hosted endpoint. You can also run both side by side in one mcpServers block.
