  • create_diagram

    Create a new empty diagram in a workspace, optionally inside a folder. Returns the new diagram's id. Use generate_diagram afterward to populate it with content. Use list_folders first to find the folder_id if you want to place it in a specific folder.

  • create_folder

    Create a new folder in a workspace. Returns the new folder's id and name. Optionally nest it inside an existing folder.

  • create_workspace

    Create a new workspace. Returns the new workspace's id and name.

  • delete_diagram

    Permanently delete a diagram and its content. This cannot be undone.

  • generate_diagram

    Generate a visual diagram from a structured graph of nodes and edges, and save it to an existing CanvasKeep diagram. You provide the logical structure (what components exist and how they connect), and CanvasKeep handles all visual layout automatically - do NOT try to compute x/y positions. NODES: Create one node for every distinct component, actor, system, service, or data store mentioned in the user's request. Give each a short, clear label (under 30 chars). Choose the right type for visual distinction. EDGES: Create one edge for every meaningful interaction, data flow, API call, or depend…

  • get_diagram_scene

    Read the raw Excalidraw scene of a diagram: the full elements array (with ids, x/y, width/height, styles, text, arrow bindings) and appState. Use this before save_diagram_scene to make precise edits: read the scene, modify the elements you need, then write the complete array back. Embedded image data (files) is omitted by default because it can be very large; set include_files to true only if you need it.

  • get_diagram_summary

    Get a summary of an existing diagram: its title, workspace, element count, and when it was last updated. Does NOT return the raw scene data.

  • list_diagrams

    List all diagrams in a workspace. Returns each diagram's id, title, and last updated timestamp.

  • list_folders

    List all folders in a workspace. Returns each folder's id, name, and parent_folder_id. Use folder ids when creating diagrams inside a specific folder.

  • list_workspaces

    List all workspaces in your CanvasKeep account. Returns each workspace's id and name. Use this first to find the workspace_id needed by other tools.

  • save_diagram_scene

    Overwrite a diagram's scene with a full Excalidraw elements array. Use this for manual layout and precise edits (moving, restyling, relabeling, adding or removing specific elements). IMPORTANT: this REPLACES the entire scene. Always call get_diagram_scene first, modify that array, and send back EVERY element you want to keep. Any element missing from the array is deleted. To remove an element you may also set "isDeleted": true on it. When changing an element, bump its "version" and set a new random "versionNonce" so open editors pick up the change. Text inside a shape is a separate text elem…

  • update_diagram

    Update a diagram's title (rename it).
