MCP tool
launch_campaign
Activate every pending/errored channel-campaign via its adapter (API channels go live or pending-approval; workflow channels like cinema/AdSmart start a booking workflow). Sandbox workflow lines can also resume here. Live paid-media activation stages provider objects paused; a human must record exact provider creative approval and issue fresh supplier authority before resume can enable the manifest-bound hierarchy. Before first launch, every campaign line must have at least one selected creative for the same channel with a completed, non-failing policy precheck; generate_creative with campaignId attaches new work automatically, or use set_campaign_creatives to select reusable existing work. Returns the refreshed campaign plus per-line launchErrors if any adapter failed.
Input
Pass fields from this schema as the tool arguments. Runtime ownership, product scope and readiness checks still apply.

}REST mapping and authority
The tool wraps this REST endpoint. The mapping identifies path/query/body transformations and approval or idempotency headers.
{
"method": "POST",
"path": "/api/v1/campaigns/{campaignId}/launch",
"pathFields": [
"campaignId"
],
"pathSchema": {

"type": "string",
"description": "campaign id, e.g. cmp-1a2b3c4d"
}
},
"additionalProperties": false,
"required": [
"campaignId"
]
},

"headers": {
"x-chorus-agent-step-id": "agentStepId",

},

"responseMapping": "REST JSON is returned as MCP structuredContent and a compatibility text block; privacy-sensitive tools validate their output schema."
}Output
This is the registered MCP output envelope. Nested fields are only modeled where the schema explicitly defines them.

"properties": {},
"additionalProperties": {}
}Safety annotations
{
"readOnlyHint": false,
"destructiveHint": true,
"idempotentHint": false,
"openWorldHint": true
}Annotations help a client present the tool. The API independently enforces authorization and exact action approvals. Error and retry guidance →
