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. 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.

• Auto-Extract Auth — Reads tokens from Slack, Discord, Teams, KakaoTalk, and Channel Talk desktop apps, with browser fallback. Webex and Instagram tokens extracted from Chromium browsers. Telegram and WhatsApp authenticate with a one-time code — still under a minute
• Act As Yourself — Extracts your user session — not a bot token. Your agent sends messages, reacts, and searches as you. Need bot mode? Bot CLIs are included too
• One Interface — Consistent command style across 7 platforms for supported actions (e.g. message send, message search, channel list, snapshot). Learn once
• Agent-Native Output — JSON by default for LLM tool use. --pretty for human-readable. Structured output your agent can parse and act on
• Token Efficient — CLI, not MCP. One skill file, one shell command per action. No server to run, no tool registration. (Why not MCP?)
• Persistent Memory — Stores workspace IDs, channel mappings, and preferences in ~/.config so your agent never asks twice
• TypeScript SDK — Import clients directly into your app. Full type safety with Zod schemas
