Call the deleteCampaign MCP tool

Permanently delete a PAUSED or COMPLETED campaign, including its enrolled leads' progress and all of its stats history. This cannot be undone. Refuses an ACTIVE campaign (reason pause_first: pause it with pauseCampaign first, then retry) and refuses a DRAFT campaign (use deleteDraftCampaign instead, which is ungated since a draft never caused LinkedIn activity). Also refuses a campaign that still has reply-agent pause history referencing it (reason campaign_in_use, checked before any preview so it costs nothing): that history cannot be repointed, so it is a permanent block; contact support if it needs to be removed. Two-step: the FIRST call (no confirm_token) returns a preview naming the campaign, its status, and how many leads are enrolled, and deletes NOTHING; call again with the same campaign_id plus confirm_token to execute. Changing anything about the request, including the enrolled-lead count moving between preview and confirm, invalidates the token and returns a fresh preview instead of applying a stale approval.

Called through the Actions bridge: the response is that tool's own result, wrapped as { data: <tool result> } under HTTP 200. Billing, daily-cap, and confirm-step outcomes are embedded INSIDE data, never remapped to an HTTP status (see the templated /api/v1/actions/{toolName} operation above for the full protocol, and x-mcp-actions for this tool's machine-readable scope/cap/confirm_behavior fields). Authentication, request-shape, and optional idempotency-protocol failures still use their documented non-200 statuses.
