linkedin_enrichment

Enrich person comment activity

The target’s recent comments across OTHER people’s posts (activity feed, Comments tab): where the target spends attention, and warm entry points for an opener. Each item carries the PARENT POST too, so you can read what they were reacting to without a second call. cached 7d, paginated. Addressed by profile_id alone. PAGING: the end of the feed is a MISSING paging.next_page_cursor, never an empty page, because member filtering can empty a page mid-feed; there is no total, LinkedIn reports 0 for this feed whatever is in it. The target’s OWN posts are person-posts; the commenters OF a post are scraping.

Contract:

MCP tool enrich_linkedin_person_comment_activity, registry package mcp.linkedin/linkedin_enrichment, mount linkedin.enrichment.
Operation action, response envelope action.
Flags: paced: a call spends the enrichment smart-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 429 rate_limited with context.retry_after, and the same call succeeds from that moment. Parallel calls on one account queue behind each other.

Authorizations

Authorization

string

header

required

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-SID

string

header

required

Team scope for tokens that do not carry one. Ignored when the token already names a team.

Body

application/json

Request body of enrich_linkedin_person_comment_activity.

profile_id

string

ln_id (ACoAA…) or sn_id (ACwAA…), interchangeable for dispatch. Provide profile_id XOR public_identifier.

Maximum string length: 128

public_identifier

string

Vanity slug from /in/…, or the whole profile URL it comes from (any linkedin.com host, locale or mwlite prefix, query and trailing slash included): the URL is reduced to the slug before dispatch, and both forms share one ledger entry. A linkedin.com URL that is NOT a profile URL is refused 422 public_identifier_not_resolvable instead of being sent as a slug. Provide public_identifier XOR profile_id. On sub-record methods a slug-only call needs a stored URN (run person-lite-profile first) or is refused not_dispatchable.

Maximum string length: 2048

page_size

integer

Items per page, 1..100 (wire default 10).

Required range: 1 <= x <= 100

cursor

string | null

Opaque cursor: pass back paging.next_page_cursor verbatim; omitted = first page.

linkedin_account_sid

string | null

Executor account (ln_ac_...). Given: the call runs on that account ONLY; a saturated or held enrichment bucket refuses 429 bucket_saturated (with retry_after). Omitted: the service auto-picks one of your connected accounts with remaining capacity (422 no_connected_accounts when none is ready, 429 when all are at capacity).

Required string length: 18

Pattern: ^ln_ac_

idempotency_key

string | null

Replay guard (team_sid, idempotency_key). A repeat with the same key returns the stored ledger outcome without running again, except a failure that answered with retry_after: once that time has passed, a repeat under the same key runs again.

Maximum string length: 128

trust_cache_max_age_days

integer | null

Accept a stored payload this many days old instead of fetching (probe tier 2, §9.5): a hit answers with served_from_cache / cache_source "data_cluster", spending no browser run and no bucket slot. Omitted, the stored payload is never consulted and the call always dispatches.

Required range: 1 <= x <= 3650

Response

action success envelope.

success

Available options:

true
