QMailing MCP Server

Give Claude (or any MCP-compatible agent) its own email address. QMailing exposes real, persistent mailboxes as MCP tools — not aliases, not disposable inboxes. Your agent can read, reply, create new mailboxes on demand, and register webhooks for inbound events.

What you can do

• "Claude, create a mailbox support@myproject.com"
• "Show me unread emails from the last 24 hours across all mailboxes"
• "Reply to that invoice email and confirm the amount"
• "Set up a webhook to ping my server whenever an email arrives at sales@"
• "Walk me through the DNS records I need to publish for my custom domain"

Tools (12)

Mailboxes: qmailing_list_mailboxes, qmailing_get_mailbox, qmailing_create_mailbox

Domains: qmailing_list_domains, qmailing_get_dns_records

Email: qmailing_list_emails, qmailing_get_email, qmailing_get_attachment, qmailing_send_email

Webhooks: qmailing_register_webhook, qmailing_list_webhooks, qmailing_delete_webhook

Security

• Scoped tokens (mailboxes:read, email:send, webhooks:write, etc.) — issue read-only tokens for triage agents
• Tokens revocable in one click from the developer dashboard
• Webhooks signed with HMAC-SHA256, 5-minute replay window, Stripe/GitHub-style verification
• 300 requests/min per token
• RFC-7807 error envelopes with stable error codes for reliable agent retry logic
