Preview the connection flow in Cursor, Claude, ChatGPT, or VS Code. The interactive playground uses live simulated schemas.
One click signs you up and lands you on setup with the mails.now MCP URL ready to paste into your client.
After you connect and sign in, ask: “Verify DKIM on outreach.example.com” or “Create twenty mailboxes.”
Talk to your agent, just like humans. Your agent understands you and fulfill your requests like a human would do.
“Is SPF, DKIM, and DMARC passing on outreach.example.com?”
“Create twenty mailboxes on outreach.example.com using first.last”
“Enroll these leads into the SaaS onboarding sequence”
“Pause any campaign with a bounce rate above two percent”
Domains, mailboxes, campaigns, and inbound mail — your assistant picks the right tools and keeps work inside your mails.now workspace.
List domains, inspect MX/SPF/DKIM/DMARC, and provision Cloudflare DNS from chat.
Create single or bulk mailboxes, aliases, and poll provisioning until ready.
Create campaigns, enroll leads, pause unhealthy sends, and sync sequence steps.
Import leads, manage lists and tags, list inbound mail, and register webhooks.
Model Context Protocol (MCP) is an open standard that lets AI assistants call external tools mid-conversation. The mails.now hosted MCP server gives your assistant access to domain, mailbox, DNS, sequencer, lead, and inbox tools directly in your current chat or IDE.
Claude (claude.ai, Desktop, and Claude Code), ChatGPT, Codex, Grok, Cursor, VS Code, Devin Desktop (Windsurf), Zed, Cline, OpenCode, Gemini CLI, JetBrains IDEs, and GitHub Copilot. Any client that supports Streamable HTTP MCP works with our endpoint.
No. Hosted MCP uses OAuth sign-in and shares the same mails.now account entitlements as the dashboard and REST API. You never need to expose or paste raw API keys inside local config files.
We publish to the Official MCP Registry as now.mails/mailapi and submit to the Claude Connectors Directory plus MCP hubs. Install with OAuth using https://mails.now/mcp/mailapi — no API key in client config.
No. MCP tool calls use the same plan entitlements as dashboard and API actions. There is no separate MCP license or markup.
Use https://mails.now/mcp/mailapi in your client settings, then reconnect and complete OAuth sign-in if prompted. You can also use the Cursor deep link cursor://anysphere.cursor-mcp/add?url=https://mails.now/mcp/mailapi.
Placing .cursor/mcp.json in your project repository restricts mails.now capabilities to that workspace. Storing it in ~/.cursor/mcp.json enables mails.now globally across repositories in Cursor. Refresh MCP servers from Settings or the command palette (Cmd+Shift+P).
Add the remote MCP server, sign in with OAuth, and start provisioning domains and campaigns from your AI assistant in seconds.
