The Mastodon MCP server

The accounts connected to the workspace: id, network, handle and status. The agent calls it first to get channel ids.

No arguments.

Saves a draft, or schedules a post or a thread, on one or more channels. The post lands on your Postbase calendar and publishes through each network's official API.

body or thread, channel_ids, scheduled_at (ISO 8601 with an offset) or schedule_in_minutes, media_ids from list_media or media_urls, channel_bodies for per-channel text, and an idempotency_key so a retried call can't post twice. Leave both times out to save a draft.

One post and how it went on each channel: published with its live link, or failed with the reason and when it will be retried.

post_id, from create_post or list_scheduled.

Edits or reschedules a draft or scheduled post before it goes out. Only the fields you pass change.

post_id, plus any of create_post's fields. scheduled_at null turns it back into a draft.

Sends a post again to the channels where it failed. Channels where it already published are left alone.

post_id.

How published posts performed: impressions, likes, comments, shares and saves per channel, with totals for the range.

from and to (YYYY-MM-DD, default the last 30 days), or post_id; channel_id, platform, sort (date or a metric), order, limit.

The images and videos in your Postbase media library, newest first. The agent passes their ids to create_post to attach them.

type (optional): image or video. search (optional): part of a file name.

Adds an image or video to your media library from a public link, for attaching to posts.

url (https). name (optional).

Posts in the workspace with their text, time and channels. Scheduled posts by default, or drafts, published or failed ones.

status (optional): scheduled, draft, published or failed.

Cancels a scheduled post before it goes out. It goes back to being a draft, so nothing is deleted.

post_id, from list_scheduled.
