EricGrill Facebook Automation
Automate Facebook Page operations -- create and schedule posts, upload videos, manage Messenger conversations, retrieve page insights, and handle scheduled content -- all orchestrated through the Composio MCP integration.

Core Workflows

Known Pitfalls
| Pitfall | Details |
|---|---|
| Scheduling too close to now | FACEBOOK_CREATE_POST with scheduled_publish_time less than ~10 minutes in the future returns HTTP 400 -- enforce a larger buffer for bulk runs |
| Unix UTC timestamps required | scheduled_publish_time must be Unix UTC -- timezone conversion mistakes cause off-by-hours scheduling or validation failures |
| Cursor-based pagination | FACEBOOK_GET_SCHEDULED_POSTS and FACEBOOK_GET_PAGE_CONVERSATIONS return subsets -- follow paging cursors to get complete data |
| Large conversation payloads | Requesting embedded messages in conversations creates huge payloads -- use FACEBOOK_GET_CONVERSATION_MESSAGES for full threads instead |
| Video processing delays | Uploaded videos may remain in processing state -- only schedule via FACEBOOK_CREATE_VIDEO_POST after the upload is usable |
| Cache page IDs | Repeating FACEBOOK_LIST_MANAGED_PAGES calls adds latency -- cache page_id per workspace/run |
| Pages only | This toolkit does not support personal Facebook accounts -- only Facebook Pages |
| Write operations need confirmation | FACEBOOK_SEND_MESSAGE and FACEBOOK_MARK_MESSAGE_SEEN cause user-visible side effects -- only call after explicit user confirmation |
