Why Agent Messenger?

You shouldn't need a bot token to send a message.

Every platform gates API access behind OAuth apps that need admin approval — days of waiting just to send a message. And even then, your agent is a bot, not you. Different name, different permissions, different context.

Agent Messenger reads session tokens from your Slack, Discord, Teams, KakaoTalk, or Channel Talk desktop app — zero config. If the desktop app isn't installed, it falls back to extracting from Chromium browsers, with auth extract --browser-profile <path> for custom Chromium profile locations. Webex and Instagram tokens are extracted directly from browsers. Telegram authenticates with a one-time phone code, and WhatsApp with a QR code or pairing code. Either way, your agent operates as you — same name, same permissions, same context. Bot tokens are fully supported too for server-side and CI/CD use cases.

[!TIP] For Slack and Discord, QR code sign-in (auth qr) is the recommended way to authenticate — it's the safest and most reliable method. It signs you in through the platform's own login flow instead of reading credentials off disk, and works even without the desktop app. See the Slack and Discord auth guides.
