    MailerLite MCP for your AI agent

    Cogny's MailerLite integration exposes 19 tools (9 read, 6 write, 4 destructive) to an AI agent over MCP. The same tools are available on every plan, from your own AI client or inside the Cogny app.

    • 9readonly reads data.
    • 6writecreates or changes something.
    • 4destructivedeletes, removes or replaces something.

    Over MCP your own AI client asks before it runs a write. To take a tool away from your agent, block it in Settings → Integrations. Plans, approvals and limits

    set it up.

    Add Cogny to your AI client once, then connect MailerLite in Cogny. Every MailerLite tool below appears in the client.

    • Claude CodeRun claude mcp add --transport http cogny https://app.cogny.com/mcp, then authorise in the browser.
    • Claude.aiSettings → Connectors → Add custom connector, URL https://app.cogny.com/mcp, then log in and pick your workspace.
