Inspect Moosend lists, subscribers, segments and campaign stats, and add or unsubscribe subscribers.
The publisher's own server: Ably MCP by usefulapi
Hosted Moosend MCP server that lets an assistant inspect mailing lists, subscribers, segments and campaign stats, and add or unsubscribe subscribers.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.usefulapi%2Fmoosend/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}Use Moosend from Claude, Cursor, or any MCP client — inspect mailing lists, subscribers, segments and campaign analytics, and add subscribers or draft campaigns. Hosted, no local install: connect with your own Moosend credentials.
Live endpoint: https://moosend.usefulapi.io/mcp · Homepage: https://usefulapi.io/moosend
https://moosend.usefulapi.io/mcp.claude mcp add --transport http moosend https://moosend.usefulapi.io/mcp, then run /mcp to log in.Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Moosend credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/moosend/
On first connect you'll provide your Moosend API key (More > Settings > API key). They're validated, stored per-user, and scoped to you — no keys in config files.
read tools are read-only; write tools mutate data (clients should confirm them); meta tools report usage, manage your subscription or send a feature request.
Each paid plan covers this server only. Ask your AI to run moosend_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with moosend_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with moosend_upgrade before then undoes the cancel. Or write to [email protected].
