But it can't receive a simple verification email.</p> <p>I built <strong>MailCat</strong> to fix this. And the setup is one prompt.</p> <h2> The Solution </h2> <p>Just paste this into Claude Code, OpenClaw, or any AI agent:</p> <blockquote> <p>"Read <a href="https://mailcat.ai/skill.md" rel="noopener noreferrer">https://mailcat.ai/skill.md</a> and set up a MailCat mailbox for yourself. Save the token securely."</p> </blockquote> <p>That's it. Your agent:</p> <ol> <li>Reads the skill.md documentation</li> <li>Creates a mailbox via API</li> <li>Saves the token</li> <li>Checks inbox when needed</li> <li>Extracts verification codes automatically</li> </ol> <p><strong>No config. No API keys to set up. Your AI reads the docs and handles everything.</strong></p> <h2> Why This Works </h2> <p>The key insight: if your AI can read documentation, it can integrate itself.</p> <p>The skill.md at <code>https://mailcat.ai/skill.md</code> is designed for AI agents:</p> <ul> <li>Clear structure</li> <li>Complete API examples</li> <li>Everything an AI needs to integrate</li> </ul> <p>You don't configure email for your AI. You tell your AI to read the docs. It does the rest.</p> <h2> Features </h2> <div class="table-wrapper-paragraph"><table> <thead> <tr> <th>Feature</th> <th>Description</th> </tr> </thead> <tbody> <tr> <td>One prompt setup</td> <td>AI reads docs and integrates itself</td> </tr> <tr> <td>Auto-extraction</td> <td>Codes and links extracted automatically</td> </tr> <tr> <td>1-hour retention</td> <td>Perfect for verification flows</td> </tr> <tr> <td>Self-hostable</td> <td>Deploy on your own Cloudflare account</td> </tr> <tr> <td>Open source</td> <td>MIT licensed</td> </tr> </tbody> </table></div> <h2> Use Cases </h2> <ol> <li> <strong>Autonomous signups</strong> - Agent registers for services</li> <li> <strong>E2E testing</strong> - Test email flows in CI/CD</li> <li> <strong>Newsletter processing</strong> - Subscribe and summarize</li> <li> <strong>Notification monitoring</strong> - Watch for alerts</li> </ol> <h2> Try It </h2> <p>Paste this into your AI agent:<br> </p> <div class="highlight js-code-highlight"> <pre class="highlight plaintext"><code>Read https://mailcat.ai/skill.md and set up a MailCat mailbox for yourself.
