Access, auth, and limits
Setup needs no API key. In Claude Desktop, open Settings then Connectors, choose Add custom connector, name it MailerLite, paste https://mcp.mailerlite.com/mcp, click Connect, and complete the OAuth login. The same URL works in Claude Web and Claude Code.
Beyond Claude, MailerLite documents the identical endpoint for Cursor, VS Code, the Gemini CLI, and ChatGPT (Pro/Plus, in beta). One server URL, one OAuth flow, and the agent inherits your account's subscribers, campaigns and automations.
Where it works and what to build
A real workflow: 'Create a re-engagement campaign for subscribers who haven't opened an email in 90 days, write three subject-line options, and schedule it for Tuesday 10am.' The agent segments the list, drafts the campaign HTML, proposes subjects, and schedules the send, without you opening MailerLite.
Because the server exposes automations and e-commerce objects, you can go further: 'Build a welcome automation for new Shopify customers and add a 10% coupon email on day 3.' The agent creates and validates the automation flow directly, then you review it in the dashboard via the deep link it returns.
Which AI clients can use MailerLite MCP?
Not every AI assistant supports MCP natively. Per-client picture for MailerLite:
| Client | Support | Notes |
|---|---|---|
| Claude (Desktop/Web) | Native MCP | Add https://mcp.mailerlite.com/mcp as a custom connector; OAuth login, no API key. |
| Claude Code | Native MCP | Add the remote MCP server URL; full subscriber, campaign and automation tools available. |
| Cursor | Native MCP | Documented by MailerLite as a supported MCP client against the same endpoint. |
| ChatGPT | Native MCP | Supported on ChatGPT Pro/Plus (beta) as an MCP client. |
| n8n | API-only (custom code) | No native MCP node; integrate via the MailerLite REST API with a Bearer API key. |
How to connect MailerLite MCP to Claude Desktop
Add this block to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows), then restart Claude Desktop. Cursor and Codex use a similar schema.
{
"mcpServers": {
"mailerlite": {
"command": "npx",
"args": ["mcp-remote", "<YOUR_MCP_URL>"]
}
}
}
// HTTP-transport MCP. Get your <YOUR_MCP_URL> from the vendor dashboard.
// Server source: https://mcp.mailerlite.com/mcp
// Claude Code (one-liner): claude mcp add mailerlite <YOUR_MCP_URL> --transport httpSome MCP servers require an API key. Check the source page for setup: mcp.mailerlite.com/mcp.
Does MailerLite MCP cost extra?
MailerLite ships an official MCP server that uses your existing subscription credentials.
- No separate MCP licence to buy. You pay for your MailerLite plan, the MCP server queries that account.
- Whether it's gated to a specific tier wasn't extracted automatically — verify the access requirements on the MCP page or pricing docs.

What you can do with MailerLite from an AI agent
Three shapes of agent workflow. Pick the row that matches how you actually use Claude / Cursor / Codex day to day.
Skip the dashboard, ask Claude
- "What campaigns underperformed this week?" answered in seconds
- Quick one-off questions without leaving the editor
- Pipe MailerLite data into your personal notes / docs without writing a script
Run client analysis at agent speed
- Hand the MCP server to your team — every consultant can ask Claude about any client's MailerLite account
- Multi-account workflows without context-switching the MailerLite UI
- Reports you'd normally spend hours on, done before standup
Production agent workflows
- Embed in your internal Codex / Cursor agents that triage MailerLite data daily
- Combine with other MCP servers in a multi-step agent chain
- Constrain agents to read-only roles to keep production MailerLite safe
Limits and gotchas
- Official MCP server — published by MailerLite themselves, so it should track product changes.
- Fallback: the REST API works for any flow the MCP server doesn't cover.
- Rate limits: MCP calls count against your underlying MailerLite API quota. Burst usage from a curious agent can drain a daily allowance fast.
Agent-readiness verdict
One of the strongest email-marketing MCP servers going: official, OAuth, zero-config, and covering subscribers, campaigns, automations, e-commerce and even email-content generation, across an unusually wide set of AI clients. It is only held back from a 9 by its beta status and a lighter public rate-limit and tool-count spec. A strong 8 out of 10, and my current pick for driving email marketing from an agent.
Moderate agent-fit with community support. MailerLite has a public API with docs and a working community MCP server, plus native Claude integration, but lacks official MCP hosting, OpenAPI spec, and webhooks for event-driven workflows. The missing structured outputs and single-language SDK options limit automation complexity.
