bam4u for AI agents

Plug disposable mailboxes straight into Claude, Cursor, VS Code & co. — via the open MCP standard. Ideal for email verification in automated flows.

What for

Email verification

Test sign-up and double opt-in flows automatically — the agent creates a mailbox and reads the code.

QA & automation

Disposable mailboxes on demand in CI/tests, no manual setup.

Privacy by default

Temporary, no real email address — data disappears automatically.

MCP endpoint

MCP Streamable HTTPhttps://mcp.bam4u.com/mcp

Use via MCP clients (Claude, Cursor, VS Code, Codex …). API key required (header Authorization: Bearer …).

Tools

create_mailbox

Creates a temporary email address (optional local part/domain).

get_messages

Lists incoming messages of a mailbox.

get_message

Reads a single message in full (subject, sender, body).

delete_message

Deletes a message from the mailbox.
