Claude Code controls your MailSlurp MCP Server

Connect this server to your terminal session and start automating. Claude Code uses `list_all_inboxes` to audit your current environment before running your test suite. It keeps your shell clean and focused. By piping these tools into your CI scripts, you gain full visibility into email delivery without leaving the command line.

Headless testing with Claude Code

This setup is perfect for automation. You can script a full registration flow using `create_random_inbox` and `wait_for_email_count` to confirm your system behaves as expected. It runs reliably in any environment, including Docker containers. You get instant feedback on your email logic without needing a browser or a GUI.

Efficient inbox cleanup with an MCP Server

Resource management is a priority in any pipeline. Claude Code calls `delete_specific_inbox` after each test run to ensure your MailSlurp account stays within limits. It prevents test data bloat. You maintain a pristine state for every deployment, ensuring your tests never fail because of stale messages in an old inbox.
