Canva Automation via Rube MCP

Prerequisites

• Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
• Active Canva connection via RUBE_MANAGE_CONNECTIONS with toolkit canva
• Always call RUBE_SEARCH_TOOLS first to get current tool schemas

Setup

1. Verify Rube MCP is available by confirming RUBE_SEARCH_TOOLS responds
2. Call RUBE_MANAGE_CONNECTIONS with toolkit canva
3. If connection is not ACTIVE, follow the returned auth link to complete Canva OAuth
4. Confirm connection status shows ACTIVE before running any workflows

Core Workflows

1. List and Browse Designs

1. CANVA_LIST_USER_DESIGNS - List all designs with optional filters [Required]

• query: Search term to filter designs by name
• continuation: Pagination token from previous response
• ownership: Filter by 'owned', 'shared', or 'any'
• sort_by: Sort field (e.g., 'modified_at', 'title')

• Results are paginated; follow continuation token until absent
• Deleted designs may still appear briefly; check design status
• Search is substring-based, not fuzzy matching

2. Create and Design

1. CANVA_ACCESS_USER_SPECIFIC_BRAND_TEMPLATES_LIST - Browse available brand templates [Optional]
2. CANVA_CREATE_CANVA_DESIGN_WITH_OPTIONAL_ASSET - Create a new design [Required]

• design_type: Type of design (e.g., 'Presentation', 'Poster', 'SocialMedia')
• title: Name for the new design
• asset_id: Optional asset to include in the design
• width / height: Custom dimensions in pixels

• Design type must match Canva's predefined types exactly
• Custom dimensions have minimum and maximum limits
• Asset must be uploaded first via CANVA_CREATE_ASSET_UPLOAD_JOB before referencing

3. Upload Assets

1. CANVA_CREATE_ASSET_UPLOAD_JOB - Initiate the asset upload [Required]
2. CANVA_FETCH_ASSET_UPLOAD_JOB_STATUS - Poll until upload completes [Required]

• name: Display name for the asset
• url: Public URL of the file to upload (for URL-based uploads)
• job_id: Upload job ID returned from step 1 (for status polling)

• Upload is asynchronous; you MUST poll the job status until it completes
• Supported formats include PNG, JPG, SVG, MP4, GIF
• File size limits apply; large files may take longer to process
• The job_id from CREATE returns the ID needed for status polling
• Status values: 'in_progress', 'success', 'failed'

4. Export Designs

1. CANVA_LIST_USER_DESIGNS - Find the design to export [Prerequisite]
2. CANVA_CREATE_CANVA_DESIGN_EXPORT_JOB - Start the export process [Required]
3. CANVA_GET_DESIGN_EXPORT_JOB_RESULT - Poll until export completes and get download URL [Required]

• design_id: ID of the design to export
• format: Export format ('pdf', 'png', 'jpg', 'svg', 'mp4', 'gif', 'pptx')
• pages: Specific page numbers to export (array)
• quality: Export quality ('regular', 'high')
• job_id: Export job ID for polling status

• Export is asynchronous; you MUST poll the job result until it completes
• Download URLs from completed exports expire after a limited time
• Large designs with many pages take longer to export
• Not all formats support all design types (e.g., MP4 only for animations)
• Poll interval: wait 2-3 seconds between status checks

5. Organize with Folders

1. CANVA_POST_FOLDERS - Create a new folder [Required]
2. CANVA_MOVE_ITEM_TO_SPECIFIED_FOLDER - Move designs into folders [Optional]

• name: Folder name
• parent_folder_id: Parent folder for nested organization
• item_id: ID of the design or asset to move
• folder_id: Target folder ID

• Folder names must be unique within the same parent folder
• Moving items between folders updates their location immediately
• Root-level folders have no parent_folder_id

6. Autofill from Brand Templates

1. CANVA_ACCESS_USER_SPECIFIC_BRAND_TEMPLATES_LIST - List available brand templates [Required]
2. CANVA_INITIATE_CANVA_DESIGN_AUTOFILL_JOB - Start autofill with data [Required]

• brand_template_id: ID of the brand template to use
• title: Title for the generated design
• data: Key-value mapping of placeholder names to replacement values

• Template placeholders must match exactly (case-sensitive)
• Autofill is asynchronous; poll for completion
• Only brand templates support autofill, not regular designs
• Data values must match the expected type for each placeholder (text, image URL)

Common Patterns

Async Job Pattern

1. Initiate job (upload, export, autofill) -> get job_id
2. Poll status endpoint with job_id every 2-3 seconds
3. Check for 'success' or 'failed' status
4. On success, extract result (asset_id, download_url, design_id)

ID Resolution

1. Call CANVA_LIST_USER_DESIGNS with query=design_name
2. Find matching design in results
3. Extract id field

1. Call CANVA_ACCESS_USER_SPECIFIC_BRAND_TEMPLATES_LIST
2. Find template by name
3. Extract brand_template_id

Pagination

• Check response for continuation token
• Pass token in next request's continuation parameter
• Continue until continuation is absent or empty

Known Pitfalls

• Uploads, exports, and autofills are all asynchronous
• Always poll job status; do not assume immediate completion
• Download URLs from exports expire; use them promptly

• Assets must be uploaded before they can be used in designs
• Upload job must reach 'success' status before the asset_id is valid
• Supported formats vary; check Canva documentation for current limits

• Canva API has rate limits per endpoint
• Implement exponential backoff for bulk operations
• Batch operations where possible to reduce API calls

• Response data may be nested under data key
• Job status responses include different fields based on completion state
• Parse defensively with fallbacks for optional fields
