Platform
Visual Pins to boards you manage
Publish image or video Pins with descriptions up to 500 characters to boards connected via Pinterest OAuth.
What you can do in CatCaster
Standard Pins
Image or video Pins with title and description text.
Multi-asset Pins
Up to five media items where the format allows.
Post metrics
Pin performance data when metrics capabilities are on the connection.
Repurpose visuals
Crop helpers for vertical Pin aspect ratios from master creative.
Limits and honest constraints
- You must connect a Pinterest account with board access; CatCaster publishes to boards you authorize.
- Pin copy is shorter than blog or LinkedIn—500-character description cap in the format registry.
- No Pinterest DM or comment auto-reply in CatCaster.
- Idea Pins and some native Pin types may not map to the standard Pin format—validate in Compose.
What AI can help with
- Write discovery-friendly Pin titles and descriptions from product pages or blog excerpts.
- Suggest seasonal keyword phrases aligned with Brand Memory (no fabricated claims).
- Batch repurposing from one hero image into Pin copy variants per board theme.
Claude, Cursor, and other agents
CatCaster exposes a remote MCP server at https://www.catcaster.com/api/mcp. Connect with OAuth (recommended) or a workspace API key. Agents discover workspaces and channels, draft posts, validate placements, schedule or publish with idempotency keys, and read analytics.

Example prompt
CatCaster MCP: create_post for Pinterest pin with this image URL and description, validate_post, then ask me which board channel to use from list_channels before schedule_post.
OAuth setup for MCP clients is documented in docs/mcp-oauth.md in the CatCaster repository (Supabase OAuth 2.1, dynamic client registration, and consent). Browse AI agent guides →

- Yes when the Pin format accepts video media and validation passes.
- Does Pinterest support inbox in CatCaster?
- No. Focus is publishing and metrics.
- Can Claude schedule Pins?
