# MailerLite tools in Cogny 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. - **Read** (9): only reads data. - **Write** (6): creates or changes something. - **Destructive** (4): deletes, 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. ## All tools | Tool | Kind | What it does | |---|---|---| | `list_subscribers` | Read | List subscribers. filter_status: active\|unsubscribed\|unconfirmed\|bounced\|junk. | | `get_subscriber` | Read | Get a subscriber by ID or email. | | `upsert_subscriber` | Write | Create or update a subscriber by email. | | `delete_subscriber` | Destructive | Delete a subscriber by ID. | | `assign_subscriber_to_group` | Write | Assign a subscriber to a group. | | `unassign_subscriber_from_group` | Destructive | Unassign a subscriber from a group. | | `list_groups` | Read | List groups. | | `get_group` | Read | Get a group by ID. | | `create_group` | Write | Create a group. | | `update_group` | Write | Rename a group. | | `delete_group` | Destructive | Delete a group. | | `list_campaigns` | Read | List campaigns. filter_status: draft\|sent\|ready\|canceled. | | `get_campaign` | Read | Get a campaign by ID. | | `create_campaign` | Write | Create a campaign. | | `schedule_campaign` | Write | Schedule a campaign. | | `cancel_campaign` | Destructive | Cancel a ready campaign. | | `get_campaign_activity` | Read | Get subscriber activity for a campaign. | | `list_segments` | Read | List segments. | | `get_segment` | Read | Get a segment by ID. | Exact input schemas come from `tools/list` once MailerLite is connected; the free plan is enough to check.
