Sequenzy/mcp

Official MCP server for Sequenzy, the AI-powered email marketing platform.
Connect Sequenzy to Claude Desktop, Claude Code, Codex, Cursor, Windsurf, VS Code Copilot, OpenClaw, and other MCP clients so your AI assistant can manage email operations with structured tools instead of hand-written API calls.
What You Can Do
- Manage subscribers, tags, lists, and dynamic segments, including bulk tag reconciliation and synthetic event testing.
- Sync segments to Meta custom audiences for Facebook and Instagram retargeting.
- Manage products and attach digital delivery files for purchase automations.
- Upload hosted email images with alt text and reusable responsive crop settings.
- Draft, update, schedule, and inspect campaigns, including resolved audience previews, persisted conversion goals, and From, Reply-To, CC, and BCC identities.
- Render campaigns, sequence steps, and templates to their exact email-safe HTML without sending.
- Add one-click Poll and NPS survey blocks to emails and inspect campaign response summaries.
- Create and edit email sequences, including multi-list/tag triggers, entry-audience and property-filtered stop conditions, sending identity overrides, existing graph restructuring, and direct step test sends to internal reviewers.
- Cancel, pause, resume, duplicate, or delete campaigns and enroll contacts into sequences.
- Manage transactional email templates and send transactional emails to shared To, Cc, and Bcc recipient lists.
- Supply localized template variants or queue AI translation for enabled locales.
- Create, preview, edit, publish, unpublish, and delete landing pages.
- Create list-scoped saved signup forms with responsive stack, row, grid, and
single-image overlay block groups (including foreground gap controls), then
return client-safe static-site embeds.
- Create, target, publish, duplicate, and deploy saved signup popups with the
same recursive block layouts.
- Connect and verify custom domains for published landing pages.
- Manage team invitations, inbox conversations, and outbound webhook endpoints.
- Generate email copy, subject lines, and multi-step sequences.
- Inspect analytics, subscriber activity, deliverability health, company-level sending pauses, integrations, published event payload schemas, sending identities, tracking settings, and dashboard URLs.
- Inspect whether "Sent with Sequenzy" is visible for a workspace, why the owner subscription does or does not remove it, and open the canonical subscription page for an upgrade or renewal. Entitlement changes apply to future sends from existing live sequences without editing their blocks.
- Diagnose why sending is paused and restore eligible hard-bounce pauses after confirming list cleanup.
- Inspect exact-recipient bounce, complaint, and email-hygiene suppression, and clean up eligible stale bounces without exposing the shared SES suppression list.
- Configure company product info, account-wide sending identity defaults, rename individual sender and reply-to profiles, manage sender domains, and inspect integration examples for common frameworks.
Every published MCP tool includes explicit readOnlyHint, destructiveHint, and openWorldHint annotations so compatible clients can display accurate tool-use affordances. Tools also publish outputSchema definitions and return structuredContent, giving clients and models machine-readable result shapes for follow-up calls.
Quick Setup
The easiest setup path is the Sequenzy wizard:
The wizard opens the browser login flow, creates a personal API key, detects supported AI clients, and configures them automatically when possible.
Hosted Remote MCP
For clients that support Streamable HTTP MCP, use Sequenzy's hosted endpoint instead of running a local stdio process:
ChatGPT and the OpenAI plugin directory use the reviewed hosted surface:
That surface shares the same implementation and keeps the standard tool set
except for six operations: connect_integration, create_api_key,
create_webhook, list_webhook_deliveries, replay_webhook_delivery, and
rotate_sequence_inbound_webhook_secret. Feedback stays available with a
reduced schema for generalized, explicitly requested product feedback.
Remote clients should authenticate with the Sequenzy OAuth flow when supported. Local and automation clients can still use the stdio package below with SEQUENZY_API_KEY.
The hosted endpoint and the stdio package support MCP specification
2026-07-28 while remaining compatible with 2025-era clients. Modern HTTP
clients use per-request discovery and method headers; existing clients keep
working through the same endpoint and package command.
