}Repost LinkedIn post
Repost a LinkedIn post from one of the team accounts (wire create-instant-repost / create-repost-with-thoughts): ONE tool, the body picks which. Without text it is the plain repost (the feed’s Repost button) and nothing else may be sent. With text it is a repost with your thoughts, a share of your own above the reposted post, which takes visibility, allowed_commenters_scope and mentions exactly as create_linkedin_post does. post_urn is the post being reposted as urn:li:activity, urn:li:share or urn:li:ugcPost (a group post cannot be reposted). Public and outward; retract with delete_linkedin_post on the answered activity_urn. Spends the posting bucket. Sends once per client_reference and reposted post (as LinkedIn files it, whichever of its urns you name): a repeat is answered, never sent twice; on a 409 read error.context.send_outcome, never resend under a new key. A plain repost has no deadline on LinkedIn’s side, so one whose answer was lost stays in doubt for an hour.
Contract:
- MCP tool
repost_linkedin_post, registry packagemcp.linkedin/linkedin_posting, mountlinkedin.content. - Operation
action, response envelopeaction. - Flags: dangerous: the MCP layer gates it behind a preview/commit token, and the effect cannot be undone through this API; paced: a call spends the
postingsmart-limit bucket of the account it runs on, and calls of one bucket are spaced per account. A short wait is slept by the server; a longer one answers 429rate_limitedwithcontext.retry_after, and the same call succeeds from that moment. Parallel calls on one account queue behind each other.

}Authorizations
Access token issued by gtm.service.id. Its access_identity claim carries team_sid, actor_sid and actor_type, and that team scope is authoritative.
Team scope for tokens that do not carry one. Ignored when the token already names a team.
Body
Request body of repost_linkedin_post.
LinkedIn account sid (ln_ac_…), the authoring account. Identity-bound: REQUIRED, posts publish AS this account.
18^ln_ac_The post to repost: urn:li:activity:, urn:li:share: or urn:li:ugcPost:.
^urn:li:(activity|share|ugcPost):\d+$Your own words above the reposted post. Omit (or blank) for a plain repost.
3000With text only. ANYONE (the default) or CONNECTIONS_ONLY.
ANYONE, CONNECTIONS_ONLY With text only. ALL (the default), CONNECTIONS_ONLY, or NONE to disable comments.
ALL, CONNECTIONS_ONLY, NONE With text only: profile mentions as ready positions over text, as create_linkedin_post takes them.

Your key for this ONE repost (max 255, byte for byte): one key per repost, the same key on every repeat of it. The key and its place (the post it reposts, as LinkedIn files it) are one repost whatever it says, and a repeat never goes out twice: it answers 200 with what the first send made (result.idempotent_replay, result.content_differs when this request says something else) or 409 naming error.context.send_outcome (in_flight, unknown with retry_after and send_decisive_at, or sent; not_sent with blocking_activity_log_sid when another repost in doubt holds the place). The same key at another place is another repost. Without a key a repost of the same post with the same words count as a repeat for an hour after they went out. check_linkedin_posting_sent asks by it.
255A person's word that an earlier attempt of THIS send is not on LinkedIn: its activity_log_sid (ln_al_...), from the 409 or check_linkedin_posting_sent, given only after someone looked on LinkedIn. Taken once the attempt can no longer land (before that: 409 send_outcome_unknown, waiting_for may_still_land, retry_after and send_decisive_at that moment): it settles that attempt not_sent and this request goes out. Moot when the attempt is no longer in doubt; another send's sid is 422 not_this_message.
18^ln_al_A person's word that an earlier attempt of THIS send IS on LinkedIn: its activity_log_sid, as for confirmed_not_sent (never both). Taken at once; it settles the attempt sent and sends nothing: the answer is 409 concurrent_send_in_flight with send_outcome sent while what it made is not known (LinkedIn is read for it), or 200 with it once a read has found it. Another send's sid is 422 not_this_message; an attempt already proved not sent is 409 confirmed_sent_contradicts.
18^ln_al_Response
action success envelope.
true action kebab-case verb; matches the route segment.
