Platform
Threads
Text-first posts with image, video, and carousel
Turn one idea into a Threads-native post—text, single image, video, or carousel—without leaving your CatCaster calendar.
What you can do in CatCaster
Text posts
Up to 500 characters per post, with AI summarization from longer master copy.
Image, video, and carousel
Single image, video up to 5 minutes, or carousels up to 20 items on one thread.
Comment replies
Read and reply to thread conversations through Threads APIs where your connection allows.
Post metrics
Performance data for published threads when metrics scopes are available.
Limits and honest constraints
- 500-character cap on post copy—longer master text must be summarized or split manually.
- Threads does not expose the same DM inbox product surface as Instagram; focus is posts and thread replies.
- Media count and duration limits differ by format; validation runs before schedule or publish.
What AI can help with
- Summarize newsletters or LinkedIn drafts into a 500-character Threads post.
- Suggest punchy openers while respecting Brand Memory tone rules.
- Draft replies to thread comments; sending follows the same human-in-the-loop inbox rules as other Meta channels.

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.
