What This Skill Does
Posts and schedules toots on Mastodon via the Publora API. Supports text-only posts, image attachments (JPEG, PNG, GIF, WebP up to 16 MB each), and video files up to 99 MB. Currently limited to the mastodon.social instance.
Publora handles scheduling and multi-step media upload coordination so you don't need to manage Mastodon's media API or upload flow directly.
When to use it
- Scheduling a toot to publish at a specific date and time
- Posting event photos to a Mastodon account
- Automating recurring Fediverse updates from an agent workflow
- Publishing hashtag-rich announcements for community discoverability
- Attaching short video clips alongside post text
Example Workflow
Here's how your AI assistant might use this skill in practice.

- 1Creates the post record via /create-post with content and the mastodon-{accountId} platform target
- 2Requests a pre-signed media upload URL via /get-upload-url using the returned postGroupId
- 3Uploads the image file directly to the pre-signed URL
- 4Confirms the scheduledTime is set to the target ISO 8601 datetime in the original request
