MailerLite MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to MailerLite and the rest of your systems. It gives your agent 110 MailerLite actions (52 reads, 38 writes and 20 that wait for a confirmation) and holds the MailerLite credential itself, so the agent never does. It paces MailerLite's limits and records every call.

Set up

Connect MailerLite in three steps.

01
Add actionlake to Claude.
Run the command once in Claude Code; its consent page can create a free sandbox: 100,000 calls a month, no card. In the Claude app, add a custom connector with the URL below and paste your key on the consent page. Creating a new sandbox from the Claude app is not yet tested by us.

02
Connect MailerLite.
Bearer token. No consent screen: your agent can connect it for you, but the key then passes through your chat. To keep it out of the model's context, paste it in the console instead. actionlake stores what you paste write-only, sealed under your tenant's key.

Make the first call. Check before a write.

Ask in plain words; Claude picks the action. Before anything changes, check validates the call and prices it, for free.

Top actions

The MailerLite API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 82 of MailerLite's 84 action names are shared with at least one other connector, so an agent learns them once.

Governance for MailerLite

Destructive actions wait for a yes.

20 MailerLite actions are destructive. These are all of them:

Delete segmentmailerlite.segments.delete
Unassign subscriber from a groupmailerlite.groups.unassign_subscriber

Unassign a product from a categorymailerlite.category_products.unassign

A destructive action runs only with confirm: true. Under the human policy the agent cannot confirm for itself: the run stops until a named person approves, in the console or from a signed link in an email. The cap on a key is refused before the call is sent, never after.

Questions

The MailerLite MCP server, answered.

Is there a MailerLite MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 110 MailerLite actions across subscribers, groups, products and campaigns, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by MailerLite.

What do I need to connect MailerLite?

MailerLite API token. The free call account { op: "connections.requirements", service: "mailerlite" } lists exactly what to paste.

Can an AI agent delete or change things in MailerLite?

Only if its key allows it, and only with an explicit confirmation. 20 MailerLite actions are destructive, including delete a product, delete group and delete a customer. Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it.

Will an AI agent use up my MailerLite API limit?

actionlake paces every call to the limits in the MailerLite service file: 120 calls a minute per connection. Repeated reads are answered from cache (52 MailerLite actions can be), which never reaches MailerLite.

What does a MailerLite action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (110 MailerLite actions page). Cache hits, searches, dry runs and calls MailerLite refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.

Which MailerLite API does it cover?

The MailerLite API (connect.mailerlite.com) at connect.mailerlite.com/api. It is built from MailerLite's documentation as read on 23 October 2026. 110 actions in 23 areas, each one in the signed service file (version 1.0.0).

Does actionlake keep my MailerLite data, and where?

actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to 5 minutes, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your MailerLite credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models.

Which AI clients can use it?

Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names.
