How do I install Inxmail Mcp?

Install globally via npm: `npm install -g inxmail-mcp`. You can also run it on the fly with `npx -y inxmail-mcp`.

How can I check if an email is blocked?

Use the `check_email_blocked` tool, which checks both the blocklist (hard bounces) and blacklist (explicit blocks).

What credentials does it need?

It reads `INXMAIL_INSTANCE`, `INXMAIL_API_KEY_ID`, `INXMAIL_API_SECRET` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.
