What it can access

  • An MCP server is a program your AI app starts and talks to. A local one runs with your user's permissions: it can see the files, environment variables and network your account can.

Before you install

  1. Pin the version you reviewed instead of always installing the latest release.
  2. Read the tool list or scripts before the first run, and keep approval prompts on for actions that write, send or delete.

  • clear_canvas

    Clear all elements from the canvas

    Export the current canvas to .excalidraw JSON format. Optionally write to a file; a path ending in .md is written in the Obsidian Excalidraw plugin format (.excalidraw.md).

  • import_scene

    Import elements and image files from .excalidraw JSON, Obsidian .excalidraw.md, a PNG with an embedded Excalidraw scene, or raw JSON data

  • export_to_image

    Export the current canvas to a PNG or SVG image. Renders headless in the canvas server (no browser tab needed); SVGs embed fonts. Set embedScene: true for a PNG that is also editable in Excalidraw.

    Duplicate elements with a configurable offset

  • snapshot_scene

    Save a named snapshot of the current canvas state for later restoration

  • restore_snapshot

    Restore the canvas from a previously saved named snapshot

  • get_canvas_screenshot

    Render the current canvas to a PNG and return it as an image. Renders headless in the canvas server (no browser tab needed). Use this to visually verify what the diagram looks like.

  • read_diagram_guide

  • export_to_excalidraw_url

    Export the current canvas to a shareable excalidraw.com URL. The diagram is encrypted and uploaded; anyone with the URL can view it. Returns the shareable link.

  • set_viewport

    Control the canvas viewport (camera). Auto-fit all elements, zoom-to-fit a subset of elements, center on a specific element, or set zoom/scroll directly. Requires the canvas frontend open in a browser.
