FAQ

Everything you need to know about running mails.now within Claude via Model Context Protocol.

Which Claude products support mails.now MCP?

claude.ai (Custom connectors), Claude Desktop, and Claude Code all work with the hosted Streamable HTTP endpoint. Add https://mails.now/mcp/mailapi (or run the Claude Code CLI), then complete OAuth when prompted.

What is the fastest way to connect Claude Code?

Run claude mcp add --transport http mails-now https://mails.now/mcp/mailapi in your terminal. Claude Code registers the remote HTTP transport for you—no JSON editing. Start a new Claude Code session (or reload MCP), enable mails.now, and finish browser OAuth.

How do I connect claude.ai?

In claude.ai, open Customize → Connectors, add a custom connector with https://mails.now/mcp/mailapi, then complete the OAuth consent in the browser. Tools show up in that chat after authorization—no local config file required.

Which email marketing tools are available via MCP?

Does this use the same credits as the dashboard?

Yes. Claude authenticates through your primary mails.now account. Provisioning, sequencer actions, and sends draw directly from your unified plan entitlements with zero markups or separate licensing fees.

Do I need a separate API key for Claude?

No. Hosted MCP uses OAuth sign-in. You never need to paste raw API keys into Claude Desktop, Claude Code, or claude.ai connector settings.
