open_campaigns_page launches Campaigns — the buyer’s campaign list with
status, flight, and budget on each row. Opening a row shows that campaign’s
workspace: its media buys, creatives and their per-seller review status, and
for a draft campaign the Review & go live
receipt.
It is a widget launcher: the tool returns the shared MCP App directive for
ui://agentic-api/campaigns/mcp-app.html plus the focus it was given, and the
Page self-fetches through V3 search({kind: "campaign"}),
get({kind: "campaign"}), and, when it needs the seeded header label,
get({kind: "advertiser"}). The host keeps these named reads bound to this
Page; it is buyer-only and read-only.
Arguments
Resolve names to ids first with
search(kind: "advertiser") or
search(kind: "campaign"); never invent an id.
From an agent (MCP)
“Show my campaigns” opens the unscoped Page:content names what was opened — for example
Opened Campaigns Page focused on "Spring launch" (active, managing); scoped to advertiser "Acme".
— and structuredContent.params carries the seed the Page reads
(advertiserId, advertiserName, campaignId). When the focused campaign is
still a draft, the summary points at open_campaign_receipt.
Text answers
For an answer in words — how many campaigns, which are paused, one campaign’s budget — usesearch(kind: "campaign") and get(kind: "campaign", id)
instead. The launcher never enumerates campaigns.
