Platform
Facebook Pages—not personal profiles
Connect Facebook Pages you manage, then schedule feed updates and Stories with the same master post you use for other channels.
What you can do in CatCaster
Page feed posts
Text, single image, multi-image carousel, and video posts to Pages you administer.
Page Stories
Vertical Stories with image or video, subject to Meta duration and aspect rules.
Inbox
Page messages and comment threads with AI-assisted draft replies and human send.
Analytics
Page and post metrics when analytics capabilities are present on the connection.
Limits and honest constraints
- Personal Facebook profiles are not publishing destinations—only Pages.
- Very long Page post text is allowed by the network (tens of thousands of characters); CatCaster still validates against the format you select in Compose.
- Some Page roles may lack permission to publish; reconnect or pick a different Page if validation fails.
- Story and feed media must meet Meta file-size and duration limits enforced at publish time.
What AI can help with
- Adapt thought-leadership copy into shorter Page-friendly updates while keeping your voice.
- Repurpose a LinkedIn or blog excerpt into a Page post plus optional image caption.
- Draft replies for Page inbox threads; auto-send modes in settings still require your approval rules.
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
Using CatCaster MCP, list_channels and create a Facebook Page feed draft from this bullet list. validate_post before scheduling. If I ask about messages, use list_inbox_conversations for Facebook only and draft_inbox_reply—never send_inbox_reply without my explicit yes.
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 →
Frequently asked questions
- Can I post to my personal Facebook profile?
- No. CatCaster publishes to Facebook Pages via the Page APIs, not personal timelines.
- How do I pick which Page to use?
- After OAuth, CatCaster shows Pages you manage so you can connect the right one per workspace channel.
- Are Facebook Stories supported?
- Yes, as a placement in Compose alongside Page feed formats, with 9:16 media requirements.
- Can an AI agent schedule Page posts for me?
- Yes over MCP: create_post, validate_post, then schedule_post or publish_post with your confirmation. Mutations are audited and idempotent keys prevent duplicate publishes.
