+# Messaging
+
+How Claude Code sends and receives messages, compared to OpenClaw.
+
+## OpenClaw: Native channel integrations
+
+OpenClaw ships with 15+ channel connectors out of the box:
+Slack, Discord, Telegram, Email, SMS, WhatsApp, and others.
+Each is configured in a single YAML block. No additional setup.
+
+## Claude Code: MCP servers + native Telegram
+
+Claude Code uses MCP servers for most messaging channels.
+Telegram is the exception: it has native support since v2.1.80.
+
+### Native Telegram (no MCP needed)
+
+Since v2.1.80, Claude Code has a Channels feature with Telegram support.
+Since v2.1.81, permission relay allows approving tool calls from your phone.
+
+Install the Telegram plugin in Claude Code settings, connect your account,
+and Claude can send messages and wait for your approval before executing
+sensitive actions - from your phone, without opening a laptop.
+
+This is the closest to OpenClaw's native channel experience.
+See `telegram-channels-setup.md`.
+
+### MCP servers for other channels
+
+| Channel  | MCP Server                     | Notes                    |
+|----------|-------------------------------|--------------------------|
+| Slack    | `@modelcontextprotocol/slack` | Official MCP server      |
+| Discord  | Community MCP servers         | Search MCP registry      |
+| Email    | SMTP/IMAP MCP servers         | Several available        |
+
+The `.mcp.json` in this repo includes commented examples.
+See `slack-setup.md` for a complete walkthrough.
+
+## Honest assessment
+
+OpenClaw is easier for multi-channel messaging: install once, configure in YAML,
+done. Claude Code requires setting up separate MCP servers per channel.
+
+For single-channel use (Telegram), Claude Code's native support is now comparable.
+For complex multi-channel workflows, OpenClaw has the advantage.
