Safety check

  • Pass

    Publisher verified

    Repo is in the excalidraw GitHub organization with homepage mcp.excalidraw.com; Claude's directory lists Excalidraw as publisher with an Anthropic verified badge.

  • Pass

    Auth model

    No authentication required per the Claude listing; it only draws and exports diagrams.

  • Pass

    Write and delete access

    No tools touch your files or accounts. export_to_excalidraw uploads the diagram to excalidraw.com, which is a data-sharing action to be aware of.

  • Pass

    Tool-description injection scan

    Read src/server.ts tool descriptions. The read_me cheat sheet contains formatting instructions for drawing (for example always start with cameraUpdate), which are task guidance, with nothing about hiding actions or exfiltrating data.

  • Pass

    Repo maintenance

    excalidraw/excalidraw-mcp: not archived, last push 2026-03-24 (about 7 months), about 5,536 stars; low activity but a small server.
