Read audiences, groups, mailings and campaign results without sending email or changing contacts.
The publisher's own server: Ably MCP by usefulapi
Read-only access to an Emma email marketing account: audiences, groups, members, mailings and campaign response metrics.
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%2Femma/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.

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.
Pro covers this server only. Subscribe with emma_upgrade (it returns a Stripe Checkout link). Cancel any time with emma_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running emma_upgrade before then undoes the cancel. Or write to [email protected].
