Environment variables

  • EUSEND_API_KEY required secret Eusend API key. Use an eu_test_ key to trial calls without delivering mail.
  • EUSEND_FROM Default sender address, so the assistant does not guess an unverified one.
  • EUSEND_REPLY_TO Default reply-to address used when a send omits one.

Frequently asked questions

What is Eusend?

Send transactional email and manage domains, audiences, and broadcasts from any MCP client.

How do I install Eusend?

It runs as a remote server. In Claude Code: claude mcp add --transport http eusend 'https://mcp.eusend.dev/mcp' --header 'Authorization: <Bearer token carrying your eusend API key. Omit to sign in with OAuth instead.>'. For other clients, paste the JSON configuration from this page into their MCP settings.

Does Eusend need an API key?

Yes. It expects EUSEND_API_KEY, Authorization, which you set in its configuration.

Who maintains Eusend?

It is published by dev.eusend. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
