Mailtrap MCP Server update: Claude Extension

  • The Mailtrap MCP server is now available as a desktop extension for Claude.

  • Download the .MCPB file from our Releases.

  • If you have Claude Desktop installed, the file will open automatically so you can complete setup.

What you can do with our MCP right now:

  • Send an email via the Email API (domain verification required).

  • Send an email to your sandbox (great for testing before sending to real recipients).

  • Manage templates - connect the MCP and ask it to create or modify templates.

Local setup in other tools:

  • For editors like Cursor and VS Code, we provide one-click install links (see the README).
