Overview

Sequenzy/mcp MCP server connects MCP clients to Sequenzy for email marketing operations, including audience management, campaigns, sequences, transactional messages, analytics, and AI-assisted content. It can run locally through stdio with npx or remotely through Sequenzy's Streamable HTTP endpoint, using an API key or supported OAuth flow. Reach for it when an agent needs to configure email infrastructure, inspect delivery status, build automations, or operate campaigns without hand-written API requests.

Use cases

  • Manage subscriber lists, tags, segments, and campaign audiences
  • Configure sending domains, tracking defaults, and sender identities
  • Create and schedule campaigns or multi-step email sequences
  • Diagnose paused sending and review deliverability status
  • Connect integrations and inspect synchronization health

Key features

  • Campaign, sequence, and transactional email management
  • Subscriber, list, tag, and segment operations
  • Sending-domain verification and deliverability diagnostics
  • Company, API-key, tracking, and sender-setting administration
  • Integration and Shopify automation configuration
  • AI-generated email copy and sequence content

How Sequenzy MCP works

What Sequenzy/mcp MCP server does

Sequenzy/mcp MCP server exposes Sequenzy's email marketing platform as structured MCP tools. It covers both operational work and account administration: an agent can select a company, inspect account permissions, manage company and brand settings, configure sending identities, and generate dashboard URLs for common resources.

Email workflows include subscribers, tags, lists, dynamic segments, campaigns, sequences, transactional templates, landing pages, signup forms, popups, and analytics. The material also supports AI-generated email copy, subject lines, translations, and multi-step sequence drafts. Campaigns and sequence content can be rendered to email-safe HTML for inspection before sending.

The server also handles delivery foundations. It can add and verify sending domains, inspect SPF, DKIM, MAIL FROM, and aggregate status, diagnose paused or suspended sending, and resume an eligible hard-bounce pause after list cleanup has been confirmed. Tracking, attribution, UTM settings, unsubscribe behavior, double opt-in, integrations, and Shopify automation settings are available through dedicated operations.

How it works

For local clients, the package runs as an stdio MCP process launched with npx -y @sequenzy/mcp. The client sends tool calls, and the server communicates with Sequenzy using the configured API key. Company selection matters for subsequent calls, so workflows can first identify or select the active company before changing company-scoped resources.

Sequenzy also provides a hosted Streamable HTTP endpoint at https://api.sequenzy.com/v1/mcp. Supported remote clients can use OAuth when available. The OpenAI-reviewed endpoint uses a reduced surface: several credential- or webhook-related operations are excluded there, including integration connection and API-key creation.

Tools publish read-only, destructive, and open-world annotations, along with output schemas and structured content. This gives compatible clients information about the expected risk and result shape of each operation.

Setup and configuration

The basic local requirement is the SEQUENZY_API_KEY environment variable. The package can be added to an MCP client's server configuration with npx as the command and -y @sequenzy/mcp as its argument. The optional SEQUENZY_API_URL variable changes the API base URL, while SEQUENZY_APP_URL changes the dashboard base URL used by application URL helpers.

An alternative setup path is Sequenzy's npx @sequenzy/setup wizard. The README names Claude Desktop, Claude Code, Codex, Cursor, Windsurf, and VS Code Copilot as supported client examples.

Tools and capabilities

The available operations include:

  • Read and update company context, email branding, sending defaults, tracking settings, synchronization rules, and Shopify automation settings.
  • Create, inspect, rename, update, list, and revoke company API keys, subject to the permissions of the active key and the route being used.
  • Add, inspect, and verify sending domains, then review deliverability and sending-status diagnostics.
  • Inspect integrations, compare provider capabilities, connect supported providers, and retrieve framework-specific integration guidance.
  • Build application links for campaigns, landing pages, sequences, emails, settings, subscriptions, domains, and sent-message details.
  • Manage campaigns, sequences, transactional email templates, landing pages, signup forms, popups, audiences, and analytics through the broader Sequenzy tool set described in the README.

Limitations and notes

The active company and API-key or OAuth scopes determine what a client can access. Some operations are deliberately unavailable on the OpenAI-reviewed route, and standard MCP may return secrets for operations such as API-key creation or credential-based integration setup. The README advises using the dashboard or local CLI when secrets should not enter an AI conversation.

Sequenzy/mcp MCP server can process workspace, subscriber, campaign, engagement, commerce, delivery, and integration data depending on the requested tool. The provided privacy guidance prohibits submitting payment-card data, health information, government identifiers, credentials, precise geolocation, and other restricted data in open-ended fields. Sending recovery also has a condition: a hard-bounce pause must be explicitly confirmed as cleaned before it can be resumed.

Frequently Asked Questions about Sequenzy MCP

Sequenzy/mcp is an MCP server that connects AI clients to Sequenzy's email marketing platform. Its main tools manage companies, subscribers, lists, segments, campaigns, sequences, transactional email, sending domains, integrations, tracking settings, Shopify automation, analytics, and AI-generated email content through structured MCP calls.

Install it by configuring an MCP client to run `npx` with `-y @sequenzy/mcp` and provide `SEQUENZY_API_KEY`. Sequenzy also offers an `npx @sequenzy/setup` wizard that can create a key and configure supported clients automatically.

Yes, the README names Cursor as a supported client. Configure Cursor with the standard stdio command, or use Sequenzy's hosted Streamable HTTP endpoint if the client supports that transport.

Sequenzy/mcp requires `SEQUENZY_API_KEY` for the local stdio package. `SEQUENZY_API_URL` and `SEQUENZY_APP_URL` are optional overrides for the API and dashboard base URLs.
