Claude.ai
Ask Claude what is stalled, then have it follow up from the same chat. Your pipeline lives where you already work.
Claude Code & Cursor
The assistant that ships your product can now run outreach too. Research, write, and move deals without leaving the editor.
Any MCP host
ChatGPT, Gemini, or whatever you already use. MailMoo plugs in and the whole go-to-market process runs from that chat.
A comprehensive GTM toolkit
Each tool answers a whole question. The full reference lives in the docs and always matches the running server.
See what needs doing
The triage queue ranks stalled deals first. Unread conversations sit next to it, so your assistant starts with the work that actually matters.
Read the full picture
Leads, campaigns, conversations, and posts come back in one call. No stitching together a handful of endpoints to answer a simple question.
Act from the same chat
Update a lead, write a note, start or pause a campaign, or send a message. Scoped API keys decide how far the assistant can go.
MailMoo MCP FAQ
What is the MailMoo MCP server?
MailMoo is the most comprehensive sales and go-to-market MCP server on the market. It lets Claude, Cursor, ChatGPT, or any MCP host run the process end to end: find what needs attention, read the workspace, and act on leads, campaigns, and conversations. The endpoint is https://app.mailmoo.io/api/mcp. It uses Streamable HTTP and authenticates with a MailMoo API key.
Which clients can connect?
Any MCP-capable host. Claude, Claude Code, Cursor, and ChatGPT all work. Most clients take a URL and an Authorization header. Claude.ai uses a form instead of a config file: Authentication → None, then a request header named authorization with the value Bearer sk_live_YOUR_KEY.
What can an assistant do with my workspace?
Find what needs attention, read leads, campaigns, and conversations, then update a lead, write notes, start or pause a campaign, or send a message. Two tools reach a real person: sending a message, and starting a campaign. Give the assistant its own key you can revoke, and keep your client's confirmation prompts on.
Should I use MCP or the MailMoo Agent?
Use MCP when your own assistant should research prospects and reach out as part of a wider workflow. Use the MailMoo Agent when you want to build, launch, and adjust campaigns inside MailMoo itself. The agent runs with your signed-in session, so it can also import leads, build sequences, and walk you through setup.
