MailerLite for AI agents
MailerLite is an email marketing platform for building campaigns, automations, landing pages, and e-commerce integrations for small and mid-sized businesses. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.
What agents do in MailerLite.
Add a subscriber to a group
Add a new subscriber to a group so they enter the right automation.
Check account information
Look up account info and plan limits before setting up a new campaign, read-only.
Approve before deleting a subscriber
Require approval before deleting a subscriber, since it erases their engagement history.
86 MailerLite actions, graded by risk.
Every MailerLite action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

MailerLite in three steps.
- 01Your users connect MailerLiteThey add their MailerLite api key on Arc0 Connect, under your brand. It goes straight into the vault.
- 02You set the rulesReads run, writes like “create Field” can wait for the user, and “delete Field” can be denied outright.
- 03Any agent can actYour agent calls MailerLite through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
await arc0.policies.set('mailerlite', { read: 'allow', write: 'ask', // create_field destructive: 'deny', // delete_field }) # Claude Code: the same connection, one URL $ claude mcp add --transport http arc0 \ https://mcp.arc0.ai/u/u_8f2
How MailerLite connects.
Users add their MailerLite api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.
The same MailerLite connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →
- AUTH
- API key
- CREDENTIALS
- Per-tenant encrypted vault
- MODEL SEES
- Results only, never credentials
- AUDIT LOG
- Every call, on every plan
Use MailerLite from any agent.

MailerLite and Arc0, answered.
Can I use MailerLite with Claude, ChatGPT or Cursor?
Yes. Connect MailerLite to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the MailerLite actions you allow.
How do users connect MailerLite?
Users add their MailerLite api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.
Which MailerLite actions can my agent take?
86 in total: 38 read, 34 write and 14 destructive, such as “create Field”. Your policies decide which of them each agent may call.
Can I stop my agent from deleting things in MailerLite?
Yes. Actions like “delete Field” are graded destructive. Set destructive actions to deny, or to ask so the user approves each one, and blocked calls still show up on the audit log.
Can my own backend call MailerLite too?
Yes. The same MailerLite connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
Plug MailerLite into your agent.
Your users connect MailerLite once, under your brand. Your agent gets 86 actions behind your policies, with every call on the record.
