Tools

Seventeen tools grouped by shape — workflow helpers orchestrate common flows end-to-end, primitive tools expose fine-grained CRUD, and the instruction tool returns procedural guidance merged with live account state.

Tool Name	Description
`mailchimp_account`	Account profile, plan, data center, total subscribers, and the Chimp Chatter activity feed.
`mailchimp_audiences`	Manage audiences (lists) — read, create/update, per-audience analytics, signup-form config. No delete.
`mailchimp_audience_overview`	One-call audience health digest: info, stats, growth history, top email clients, merge-field schema.
`mailchimp_subscribers`	Subscriber CRUD + tags/notes/activity. `archive` is the strongest delete available.
`mailchimp_upsert_subscriber`	Add or update a subscriber idempotently with status, merge fields, tags, and optional note.
`mailchimp_find_subscriber`	Locate a subscriber by email in one audience or across the account.
`mailchimp_import_subscribers`	Batch add/update subscribers (capped at 500/call). Status defaults to `pending` (double-opt-in).
`mailchimp_segments`	CRUD for audience segments (saved, static, fuzzy) plus member listing and batch add/remove.
`mailchimp_merge_fields`	Read + create/update custom subscriber attributes. No delete — drops data across all subscribers.
`mailchimp_campaigns`	Campaign record management: list/get/create/update, replicate, content, checklist, RSS/resend controls.
`mailchimp_send_campaign`	Compose and send (or schedule/test) a campaign in one call. Elicits human confirmation on send/schedule.
`mailchimp_replicate_campaign`	Duplicate a campaign with optional overrides, then draft/test/send/schedule. Same elicit + cleanup semantics.
`mailchimp_reports`	Campaign reports — generic slicer across ten dimensions (clicks, opens, locations, etc.).
`mailchimp_campaign_report`	Post-send analytics digest — headline metrics + top 5 slices in one response.
`mailchimp_templates`	Email template CRUD (base, user; `gallery` requires a paid plan).
`mailchimp_search`	Global search across members or campaigns. Lightweight discovery — use `find_subscriber` for detail.
`mailchimp_playbook`	Returns a structured procedural playbook merged with live account state. Advice-only, no writes.
