Call the getCampaignFunnel MCP tool

Get one campaign’s conversion funnel (pass campaign_id from getCampaigns): the stage-by-stage counts with the conversion rate between each stage. FOUR shapes depending on campaign type/sequence: outreach (leads → requests → accepted → replied → positive → booked); lead-magnet (captured → DMs → replied → booked); retargeting/re_engagement (enrolled → messaged → replied → positive → booked - no requests/accepted stage, since a retargeting sequence never has a connection step; messaged also counts a lead who messaged in first, before their drip fired); pure-InMail outreach, detected by a send_inmail step with no connection_request (sent → replied only - no requests/accepted/booked stage). Use to answer "how is this campaign converting / where is it leaking". Counts default to all-time; pass days_back (1-365) to window them (the InMail shape is always all-time regardless of days_back, with a note when a window was requested). Pass granularity:"daily" for a day-by-day series instead of one totals block (max 90 points; a window longer than 90 days truncates to the most recent 90 with truncated:true; a note explains when a column is not meaningful for the type) - use it for "how did last week compare to the week before". booking_rate = meetings booked / positive replies for outreach and retargeting campaigns, and meetings booked / replies for lead-magnet campaigns (LM funnels do not track positive-reply classification); the InMail shape has no booking_rate or meetings_booked field at all.

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.
