Temporary inboxes for agent signup QA — create disposable addresses, wait for verification email, extract OTP or magic links. Use when automating signup, login, or email verification without parsing HTML manually.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# MailAgent MailAgent provides **programmatic disposable inboxes** for AI agents: receive OTP codes and magic links during signup flows, simulate inbound mail in CI, send/reply on verified domains, and diagnose timeouts. Official docs: https://agents.navorina.ai/docs/agents.html ## When to use - Signup or login that sends a verification email - Need OTP or magic link without hand-parsing HTML - E2E / agent task: "register with a temp email" - QA without real SMTP (`mailagent_simulate_message`) - **Not** for human privacy burners — programmatic agent inboxes with allowlists ## Install (pick one) ### Cursor (project) MCP in `.cursor/mcp.json` → `@mailagent/mcp` or `mcp/dist/index.js`. Skill auto-loads from `.cursor/skills/mailagent-mcp/` (synced from this file). ### Agent Skills catalog (repo root) ```bash npx skills add navorina-labs/MailAgent --skill mailagent ``` ### OpenAI Codex ```bash codex plugin marketplace add navorina-labs/MailAgent codex plugin add mailagent@mailagent ``` Guide: https://agents.navorina.ai/docs/codex.html ### npm MCP (any client) ```bash export MAILAGENT_API_URL=https://mail-api.navorina.ai export MAILAGENT_API_KEY=ma_… …

How to install
mdr add hashgraph-online/awesome-codex-plugins/mailagent@sha256:fff8cbe34a825f0fThe line at the top of this page pins the label v0.2.16, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
