Frequently Asked Questions

What is Mermaid MCP Server?

MCP server that turns local projects or GitHub repositories into Mermaid diagrams and renders them via Kroki.

Is Mermaid MCP Server safe to use?

We cannot tell you that, and nobody scanning at this scale can. What we did in March 2026 was shallow-clone Mermaid MCP Server and run five keyword searches over its source: auth identifiers, CORS configuration, rate-limit identifiers, the dependency manifest against a hardcoded list of 18 known-vulnerable packages, and unguarded eval/exec calls. None of them matched. A text search cannot follow a variable, judge intent, or tell you what a server does once it is running, so "nothing matched" is not "safe". What the scan does and does not cover is written out at /mcp/security.

What are alternatives to Mermaid MCP Server?

Similar MCP servers include Blender MCP, Davinci Resolve MCP, Manim MCP Server. Each serves a similar purpose but may differ in features, language, and compatibility.
