Can I use MailerLite as a CLI?

Yes. KosmoKrator exposes a MailerLite CLI through kosmo integrations:call and the provider shortcut command. Commands can return JSON for scripts, CI, and coding agents.

Can I expose MailerLite through MCP?

Yes. The KosmoKrator MCP gateway can expose selected MailerLite tools to clients such as Claude Code, Cursor, Codex, and other MCP-compatible tools.

Where are MailerLite credentials stored?

MailerLite credentials are configured in KosmoKrator's local integration settings and reused by CLI, Lua, and MCP gateway surfaces.

Can I deny write access for MailerLite MCP tools?

Yes. Start the gateway with --write=deny for read-only clients, or use ask/allow only for trusted workspaces.

MailerLite CLI for AI Agents

Use the MailerLite CLI from KosmoKrator to call MailerLite tools headlessly, return JSON, inspect schemas, and automate workflows from coding agents, scripts, and CI.

MailerLite CLI Setup

MailerLite can be configured headlessly with `kosmokrator integrations:configure mailerlite`.

# Install KosmoKrator first if it is not available on PATH.
curl -fsSL https://raw.githubusercontent.com/OpenCompanyApp/kosmokrator/main/install.sh | bash

# Configure and verify this integration.
kosmokrator integrations:configure mailerlite --set api_key="$MAILERLITE_API_KEY" --enable --read allow --write ask --json
kosmokrator integrations:doctor mailerlite --json
kosmokrator integrations:status --json

Credentials

Authentication type: API key api_key. Configure credentials once, then use the same stored profile from scripts, coding CLIs, Lua code mode, and the MCP gateway.

Key	Env var	Type	Required	Label
`api_key`	`MAILERLITE_API_KEY`	Secret `secret`	yes	API Key

Call MailerLite Headlessly

Use the generic call form when another coding CLI or script needs a stable universal interface.

kosmo integrations:call mailerlite.mailerlite_list_subscribers '{
  "page": 1,
  "limit": 1,
  "status": "example_status"
}' --json

Use the provider shortcut form for shorter human-facing commands.

kosmo integrations:mailerlite mailerlite_list_subscribers '{
  "page": 1,
  "limit": 1,
  "status": "example_status"
}' --json

Agent Discovery Commands

These commands return structured output for coding agents that need to inspect capabilities before choosing a function.

kosmo integrations:docs mailerlite --json
kosmo integrations:docs mailerlite.mailerlite_list_subscribers --json
kosmo integrations:schema mailerlite.mailerlite_list_subscribers --json
kosmo integrations:search "MailerLite" --json
kosmo integrations:list --json
