update_post

Edit an entirely scheduled post using its current version. Publishing posts cannot be edited.

Workflow

Access and behavior

Write or Administrator OAuth consent and a member/administrator team role are required. Tools are listed and callable only when the current grant and role permit them. Only entirely scheduled groups can be edited. A stale version conflicts instead of overwriting a teammate’s change. Changes apply to the complete sequence and its account overrides.

Arguments

Argument	Required	Type or meaning
`text`	Yes	Master text for this post. Account overrides take precedence.
`textOverrides`	No	Selected connection ID to custom text; omit a key to inherit the master.
`connectionIds`	Yes	Selected connected accounts belonging to this team; applies to the complete sequence.
`mediaIds`	Yes	Ready media IDs in attachment order for this master post.
`mediaOverrides`	No	Selected connection ID to ordered media IDs; omit to inherit, or use [] for no attachments.
`additionalPosts`	No	Later posts in order; each has text, mediaIds and optional account overrides.
`scheduledAt`	Yes	ISO 8601 UTC timestamp. Use a future time to schedule; use the current time only after publication confirmation.
`idempotencyKey`	Yes	One content-bound request key; reuse with the identical payload when retrying.
`draftSource`	No	Saved draft ID and current version, for one-time conversion into a posting group.
`postId`	Yes	Posting-group UUID returned by list_posts or create_post.
`version`	Yes	Latest record version; use 0 only when creating a new draft.

Example call

The client initializes the MCP connection before sending this JSON-RPC call. Example records are fictional.

  "params": {
    "name": "update_post",
    "arguments": {

Example result

Posted returns this object in structuredContent and a JSON text content block. A tool failure sets isError; never treat an error as a completed mutation.
