--- title: "MailerLite MCP server for AI agents - actionlake" description: "Give Claude 110 MailerLite actions through one MCP server: subscribers, groups, products. Your agent never holds the credential. 100,000 calls a month free." canonical: https://actionlake.com/connectors/mailerlite updated: 2026-10-23 --- Connectors · Email & messaging # 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. [Connect MailerLite free](https://actionlake.com/console?start=sandbox) [See pricing](https://actionlake.com/pricing) 100,000 free calls a month. No card, no email, no password: press Start a free sandbox on the next screen and keep the key it shows you. `claude mcp add --transport http actionlake https://connect.actionlake.com/mcp` the first call ``` do { action: "mailerlite.groups.list", intent: "check which MailerLite account is connected" } # List all groups · read · 1 upstream call ``` - 110 actions in one signed file - 52 read look, never change - 38 write create and update - 20 wait for a yes destructive, confirmed first Set up ## Connect MailerLite in three steps. 1. 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. `https://connect.actionlake.com/mcp` 2. 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. - `access_token` MailerLite API token ``` account { op: "connections.requirements", service: "mailerlite" } # free: exactly what to paste, and what is found for you ``` 3. 03 ### 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. ``` do { action: "mailerlite.groups.list" } # list all groups · read · 1 upstream call check { action: "mailerlite.products.create", input: { … } } # free: inputs, permissions, cost and confirmations, nothing sent ``` MailerLite at a glance **Sign-in** Bearer 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. ## More connectors like MailerLite Shares the most action names with - [Mailchimp 67](https://actionlake.com/connectors/mailchimp) - [GetResponse 45](https://actionlake.com/connectors/getresponse) - [Resend 29](https://actionlake.com/connectors/resend) - [Sinch Mailjet 28](https://actionlake.com/connectors/sinch-mailjet) - [Elastic Email 22](https://actionlake.com/connectors/elastic-email) - [Klaviyo 21](https://actionlake.com/connectors/klaviyo) Joins with, on shared entities - [BigCommerce 3](https://actionlake.com/connectors/bigcommerce) - [Adobe Commerce 3](https://actionlake.com/connectors/adobe-commerce) - [ActiveCampaign 3](https://actionlake.com/connectors/activecampaign) - [Shopify Admin 3](https://actionlake.com/connectors/shopify-admin) - [Brevo 3](https://actionlake.com/connectors/brevo) - [Lightspeed Retail X-Series 3](https://actionlake.com/connectors/lightspeed-retail-x-series) Browse - [All Email & messaging connectors](https://actionlake.com/connectors/category/email-and-messaging) - [All connectors](https://actionlake.com/connectors) - [How actionlake compares](https://actionlake.com/compare) actionlake is independent.
