Frequently Asked Questions

What is Excalidraw Architect MCP?

Is Excalidraw Architect MCP safe to use?

We cannot tell you that, and nobody scanning at this scale can. What we did in March 2026 was shallow-clone Excalidraw Architect MCP 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. At least one matched — the specific finding is in the scan report on this page. 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 Excalidraw Architect MCP?

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.
