Two tools matter more than the breadth: get_campaign_audience resolves who would actually receive the campaign, and render_email produces the exact email-safe HTML without sending — so the review happens before the irreversible step. The deliverability tools are the other unusual inclusion, diagnosing why sending is paused and restoring eligible bounce suppressions without exposing the shared list.
Sequenzy's official MCP server, covering the whole platform rather than a corner of it: audience and segmentation, campaign and sequence authoring, transactional email, landing pages, signup forms and popups, deliverability, team and inbox, plus the analytics behind all of it. Every tool publishes read-only, destructive and open-world hints and an output schema, so clients can show accurate affordances and read structured results.
- add_subscriber, update_subscriber, remove_subscriber, search_subscribers, create_subscriber_import and the bulk tag tools — the audience, including CSV import and bulk tag reconciliation
- list_lists, list_tags, list_segments, create_segment, get_segment_count and the audience-sync tools — lists, tags, dynamic segments, and syncing a segment to Meta custom audiences for retargeting
- create_campaign, update_campaign, schedule_campaign, send_test_email, cancel_campaign, pause_campaign, resume_campaign, duplicate_campaign and resend_campaign_to_non_openers — the campaign lifecycle
- get_campaign_audience and render_email — the resolved recipient list before you send, and the exact email-safe HTML without sending it
- create_sequence, update_sequence, edit_sequence_graph, insert_sequence_step, enable_sequence, disable_sequence and the enrollment tools — multi-step sequences, graph restructuring, and enrolling, pausing, moving or realigning the people in them
- create_ab_test, add_ab_test_variant, get_ab_test_stats and restart_ab_test — split tests and their results
- list_templates, create_template, set_template_localization and sync_template_localizations — templates and localized variants, with AI translation queued for enabled locales
- create_transactional_email, send_email and get_transactional_stats — transactional templates and sends to shared To, Cc and Bcc lists
- create_landing_page, publish_landing_page, connect_landing_page_domain, create_form, get_form_embed, create_popup and get_popup_embed — pages, custom domains, and client-safe embeds for forms and popups
- get_stats, get_campaign_stats, get_sequence_stats, list_email_metrics, list_campaign_events, get_subscriber_activity and list_poll_responses — performance, event streams and in-email poll and NPS results
- get_sending_status, resume_sending, get_recipient_suppression and remove_recipient_suppression — why sending is paused, restoring eligible hard-bounce pauses, and exact-recipient bounce and complaint state
- add_sending_domain, verify_sending_domain, list_sender_profiles, get_tracking_settings, connect_integration, list_webhooks and create_api_key — domains, sending identities, tracking, integrations, webhooks and keys
- generate_email, generate_subject_lines, generate_sequence and generate_sms — drafted copy, subject lines and multi-step sequences
A Sequenzy API key in SEQUENZY_API_KEY (keys look like seq_user_...), from Settings > API Keys. The quickest setup is npx @sequenzy/setup, which opens the browser login, creates the key and configures detected clients; otherwise clients run npx -y @sequenzy/mcp over stdio. Clients that speak Streamable HTTP can use the hosted endpoint at https://api.sequenzy.com/v1/mcp with OAuth instead. SEQUENZY_API_URL and SEQUENZY_APP_URL override the API and dashboard bases.
One command plus a key — npx -y @sequenzy/mcp, then supply credentials
