Integration details

Description

CrossPoster is a social media publishing workspace. Connected to ChatGPT, it lets you write, review and ship posts for the accounts you have linked in CrossPoster, without leaving the conversation. Drafts: create a draft for any connected account, read it back, list recent drafts, and search your past posts and drafts by meaning. Writing: generate new copy sized for the target platforms, or improve, shorten, rephrase or add hashtags to text you give it. Nothing is saved unless you ask for a draft. X wording: score a post's wording against CrossPoster's model trained on real X posts, aspect by aspect, and get a rewrite that adds no facts, names, links, mentions or hashtags when one scores higher. Previews: see how a draft will look on its platform, show a connected account, and list your connected platforms as inline cards. Analytics: summary metrics and recent published posts for X and LinkedIn. Publishing: publish a draft now or schedule it for later. Publishing requires an explicit confirmation step before anything leaves CrossPoster. Access is granted per permission when you connect: read, create drafts, generate content, and publish. Everything acts only on the social accounts connected in your CrossPoster workspace; connecting an account happens in CrossPoster, never from chat. A CrossPoster account is required.

Tools

21 tools agents can invoke

Return one new draft ID for create_draft or create_empty_draft. The same ID identifies that request in check_draft_job and on a retry after an uncertain or pending outcome; an ID whose job failed terminally is spent.
allocate_draft_id
Check a draft creation job by the same ID and platform passed to create_draft or create_empty_draft. Reports pending, failure, or verified saved content; never starts another draft.
check_draft_job
Provide the user with a link to connect a new social media platform. Cannot initiate OAuth directly from chat.
connect_platform
Create a draft with the supplied text under an ID from allocate_draft_id. A retry with the same ID and identical inputs settles onto the same draft; a failed job needs a new ID. Success is reported only after the draft's document is ready and its saved text reads back identical. A pending outcome can be checked with check_draft_job using the same ID and platform.
create_draft
Create a draft with no text under an ID from allocate_draft_id. A retry with the same ID and identical inputs settles onto the same draft; a failed job needs a new ID. Success is reported only after the draft's document is ready and reads back empty. A pending outcome can be checked with check_draft_job using the same ID and platform.
create_empty_draft
Write new social media copy from a prompt, sized for the target platforms (Instagram when none are given). Returns the text; no draft is created or changed.
generate_content
Rewrite one X or LinkedIn post's wording. Eight angle writers draft rewrites, a guard vetoes any that adds a fact, number, name, link, mention, hashtag, intensifier or engagement bait, and CrossPoster's model trained on real X posts ranks them; a LinkedIn post is ranked by the same X model until a LinkedIn model exists. `kind` is `accepted` when a rewrite scores higher overall and no lower on any aspect than the given text, with that rewrite in `text` and the per-aspect change on the /10 scale in `deltas`; `no_trusted_rewrite` when no rewrite qualifies; `unavailable` when rewriting cannot run. The scores rank wording against real X posts and do not predict reposts or reactions. Nothing is saved or applied to a draft.
improve_wording
Improve, shorten or rephrase the supplied text, or add hashtags to it. Returns the new version; no draft is created or changed.
improve_content
List this workspace's drafts, most recently updated first (10 by default, up to 50). Returns each draft's stored record, including its id, title, platform, status and timestamps.
list_drafts
List the social platforms connected in this workspace (only connected accounts are shown). Widget-capable MCP clients render an inline list; other clients see a plain-text summary. Read-only.
list_platforms
List the workspaces you can act in. An API key is scoped to one workspace and will list only that one; an OAuth connection lists every workspace you are a member of. `is_default` marks the one used when workspace_id is omitted.
list_workspaces
Get the performance analytics CrossPoster has stored for a connected platform: summary metrics and up to 30 recently published posts. Analytics are available only for X and LinkedIn; other platforms return a short note. Widget-capable MCP clients render an inline dashboard; other clients see a plain-text summary. Read-only.
get_platform_analytics
Render the primary image attached to a draft inline. Widget-capable MCP clients render an inline preview; others see a link. Read-only.
preview_draft_image
Show a connected platform account in this workspace. Widget-capable MCP clients render an inline badge; other clients see a plain-text summary. Read-only.
preview_platform
Render how a draft will look on its platform. Widget-capable MCP clients render an inline preview; others see a text summary. Read-only.
preview_post
Publish a draft to its connected platform now. The draft needs content (except on Pinterest) and its platform must be connected. Publishing is irreversible, so it takes two calls: the first returns `pending_confirmation` with a single-use `confirm_token`, and the post is published only when the same inputs are sent again with that token before it expires.
publish_post
Read a draft's title, platform and current text.
read_draft
Schedule a draft post for publishing at a future date and time. The time should be in ISO format.
schedule_post
Score one X post's wording with CrossPoster's model trained on real X posts. Returns each aspect as a percentile among that corpus, shown as x.x/10, and, per aspect, real corpus posts on a similar subject that scored higher, with author and link. `at_top` marks an aspect within the top of the corpus, which has no higher example; an aspect absent from the list is withheld in this model version for lack of signal. `unavailable` is true when the scorer cannot be reached.
score_x_wording
Search this workspace's past published posts and drafts by meaning. Returns up to `limit` matches (5 by default), each with its source type, similarity and text.
search_past_content
Report the signed-in CrossPoster user (id and email), the workspace tools act in when workspace_id is omitted (null if that is ambiguous), the connected client's name, and the scopes this connection was granted.

How do I improve CrossPoster's ChatGPT Plugin discoverability?

The levers are the listing surface agents actually read: names, descriptions, keywords, tool metadata, and registry health. Which lever matters depends on where discovery breaks, which is what continuous measurement shows.
