Notify

Official MCP server for Notify: send transactional email, rehearse test sends, and verify sending domains from Cursor or Claude Code.

notifycx-mcp is the official MCP server for Notify, a transactional email API for developers and AI agents. Run it with npx -y notifycx-mcp and set the NOTIFY_API_KEY environment variable. The MCP sends that key to Notify as the x-api-key header. Official registry name: io.github.notifycx/notifycx-mcp. Tools: send_email (production send from a verified from address), send_test_email (non-delivering rehearsal that does not count against quota), add_domain/check_domain/list_domains/get_domain (SPF, DKIM and DMARC verification), webhook tools (Pro+), list_email_logs, get_usage, and list_api_keys. bootstrap_start/bootstrap_confirm can create an account and key without the dashboard when no key is set yet. Production sends belong in your app (notifycx SDK or POST https://notify.cx/api/email/send), not only in the IDE. Not for newsletters, drip campaigns or drag-and-drop template studios. Docs: https://notify.cx/mcp. Source: https://github.com/notifycx/notifycx (mcp package). Skills: https://github.com/notifycx/notify-skills.

Use it from your agent

Point any MCP-capable agent (Claude, Cursor, your own) at the no-auth endpoint — it can then find Notify and the rest of the registry on its own:

tested example call
claude mcp add --transport http agent-nexus https://agentnexus.app/api/public/mcp

Agents can discover Notify through the Agent Nexus MCP server, /llms.txt or the discovery API.
