Analytics
Post and account-level metrics when LinkedIn analytics scopes are on the connection.
Limits and honest constraints
- LinkedIn inbox auto-reply is not available—CatCaster focuses on publishing and performance for LinkedIn.
- Page vs profile are separate channels; agents must target the correct channel id from list_channels.
- Video and image specs are validated; oversized files fail before queueing.
- Some LinkedIn API tiers restrict analytics frequency; metrics may lag platform dashboards.
What AI can help with
- Turn a blog post into a LinkedIn narrative with line breaks and hooks suited to B2B feeds.
- Shorten promotional copy while keeping claims aligned with Brand Memory—no invented metrics.
- Generate carousel slide captions from a single outline (you still supply images).
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
Use CatCaster MCP get_brand_context, then create_post for my LinkedIn Page with this text_post. validate_post, share the rendered length, and schedule_post only after I approve the time.
