Connect MailerLite to your AI
Credentials off one MailerLite screen, then an endpoint your client signs into. Nothing to deploy, and nothing to install.
Paste your API token into the one field the connect form asks for. No OAuth popup, nothing to refresh. The token is scoped to a single MailerLite account, so the connection is locked to that account's data.
API token
••••••••••••3f7aConnectionVerified
Set the connection read-only for reporting, or full access with approval required on writes so a campaign send, a group deletion or a GDPR forget waits for your yes. The full catalog toggle exposes rarer tools.

Drop the PopMCP URL into Claude, ChatGPT, Codex or any other supported client. It signs in through PopMCP with OAuth, so your MailerLite credential never leaves the server.

FAQ
MailerLite MCP server questions
What teams ask before putting MailerLite behind an AI client.
How much of MailerLite does this cover?
49 operations across 10 API modules: subscribers, groups, segments, custom fields, campaigns, automations, forms, webhooks, batch and timezones. 23 of those are reads and 26 are writes. 32 tools load into your AI client by default and the rest stay searchable, so a long tool list doesn't crowd out your other connections.
Do I need OAuth or an app install to connect?
No. The connect form asks for a single value, API token, which you generate in MailerLite and paste once. There is no OAuth popup and no refresh cycle to babysit. The token is scoped to one MailerLite account, so the connection can only ever reach that account's subscribers, groups and campaigns.
Can the agent create a segment?
No. Segments are rule-based and built in the MailerLite UI, so the agent can list them and read the subscribers currently matching each one, which is what reporting and audience pulls need. Groups are different: it can create, rename and delete groups, and assign or unassign a subscriber without deleting them.
Can it edit a campaign that is already scheduled?
Not while it sits in the scheduled state. Updates apply to drafts only, so cancel the scheduled ('ready') campaign first to return it to draft, make the change, then schedule or send it again.
Does it need a numeric subscriber ID, or is an email address enough?
Fetching one subscriber accepts either the numeric id or the email address in the path. Updating or deleting a subscriber needs the numeric id, while creating is an upsert keyed on email, so the same address updates the existing record instead of duplicating it. For a headline number there is a dedicated count call that returns per-status totals without paging through everyone.
Can it handle a GDPR erasure request?
Yes. A separate 'forget' call permanently erases all of a subscriber's personal data, and it is irreversible, which makes it different from a plain delete by numeric id. Keep approval-required-for-writes on so that call, like a campaign send, waits for a human yes before it runs.
Do I have to run or host the MailerLite MCP server myself?
No. PopMCP hosts it and gives you a Streamable HTTP MCP URL. There is nothing to deploy, no callback URL to register, and no infrastructure to keep running or patch.
Which AI clients can use this MCP server?
Any client that supports a remote Streamable HTTP MCP server — Claude Desktop, Claude Web, ChatGPT custom connectors, Codex and the Codex CLI, OpenCode and Z.ai's ZCode, as well as editors such as Cursor, Windsurf and Zed. Your client signs in to PopMCP with OAuth; the provider credential never leaves the server.
Why do only 32 of the 49 tools load by default?
Loading 49 tool definitions into every conversation burns context before the work starts. PopMCP loads a curated 32-tool set covering the everyday workflows and keeps the rest searchable, so your AI pulls a specialist tool only when a task needs it. You can switch a connection to the full catalog at any time.
What is the difference between a tool and a trigger?
A tool is something your AI calls — there are 49 here. A trigger is something PopMCP watches for you: 15 MailerLite events that can start work on the PopMCP side. Triggers never enter your AI client's context, and none of them ask you to paste a callback URL into MailerLite.
