GetCourier (moved)

antonioac1/courier

Gives AI agents temporary email inboxes that receive real SMTP messages and auto-extract verification codes, magic links, and OTP tokens. Exposes MCP tools like create_inbox, wait_for_email, extract_otp, and extract_magic_link. Works with Hermes, Claude Desktop, Cursor, and includes zero-dependency Python and Node clients. The API lives at getcourier.dev and handles the full workflow: service sends email to port 25, Courier extracts codes and links, agent retrieves via API and continues execution. Reach for this when your agent needs to sign up for services, handle passwordless logins, or receive verification emails without setting up Gmail OAuth.

Readme

GetCourier — email inbox + MCP server for AI agents

One call, no signup, no API key. Receive verification codes and magic links, reply and send. Live at getcourier.dev · hosted MCP at https://getcourier.dev/mcp · llms.txt · Terms

An AI agent gets its own email inbox with one HTTP call: POST https://getcourier.dev/alias with no body, no signup and no API key. The response returns the address, a read_token shown once, a 72-hour expiry and an Ed25519 identity. The agent then submits that address on a signup form and calls GET /v1/sandbox/inboxes/<alias>/wait, which long-polls until a verification code or magic link arrives and returns it already extracted.

Quickstart: an inbox in one call, a code in two

Create an inbox. No body, no auth, no account:

curl -s -X POST https://getcourier.dev/alias
