Common parameters

Two arguments appear across most tools:

Key	Format	Required	Description
`workspace`	string	required	UUID of the workspace to operate on. Obtain it from `list-workspaces`. Required by every tool except `list-workspaces`.
`timezone`	string	optional	IANA timezone (e.g. `America/New_York`) used to interpret input dates and format dates in the response. Defaults to your account timezone, then to UTC.

Write operations (create, update, schedule, delete, etc.) require the token owner to have the Member or Admin role in the workspace. See Roles and permissions.

Versions

The create-post, update-post and update-post-version tools support per-account content versions, so a single post can have different text or media for each network. The structure mirrors the REST API's post versions:

{
  "versions": [
    {
      "account_id": 0,
      "content": [
        {
          "body": "This is the default content used for every account.",
          "media": [1],
          "url": null
        }
      ],
      "options": {
        "mastodon": { "sensitive": false }
      }
    },
    {
      "account_id": 12,
      "content": [
        { "body": "A custom version just for this account." }
      ]
    }
  ]
}

Key	Format	Required	Description
`versions.*.account_id`	integer	required	The account this version targets. Use `0` for the original/default version. Exactly one version must use `0`.
`versions.*.content`	array	required	Ordered content items. Provide more than one to publish a thread.
`versions..content..body`	string	optional	The text body of this content item.
`versions..content..media`	array<integer>	optional	Media IDs to attach. Obtain them from `list-media` or `upload-media-by-url`.
`versions..content..url`	string	optional	A URL associated with the content (supported by Facebook and LinkedIn).
`versions.*.options`	object	optional	Provider-specific post options (see below).

Post summary shape

Most post tools return a compact summary optimised for agents (the heavy web payload is omitted to save tokens):

{
  "uuid": "6059e1b3-e102-4be5-951b-82698abd9ee3",
  "status": "scheduled",
  "scheduled_at": "2026-07-01 09:00:00",
  "published_at": null,
  "created_at": "2026-06-25 14:12:03",
  "accounts": [
    { "id": 12, "name": "Acme", "username": "acme", "provider": "x", "authorized": true }
  ],
  "tags": [
    { "id": 3, "name": "Launch" }
  ],
  "content": "We just shipped a big update 🚀",
  "media_count": 1
}

status is one of draft, scheduled, published, failed, needs_approval, publishing or trash. content is the plain text of the post's original version, with multiple content items joined by blank lines.
