Claude Code Channels + Permission Relay: Approve Tool Calls from Your Phone via Telegram, Discord, or iMessage While Agents Run Autonomously

Claude Code Docs·high signal

Claude Code Channels (research preview, March 20) let you send messages from Telegram, Discord, or iMessage into a running session with full filesystem/MCP/git access. v2.1.81 added permission relay — channel servers that declare the capability forward tool approval prompts to your phone. Both terminal and phone stay live; whichever answer arrives first wins. This unlocks 'fire and forget' agent workflows where you approve high-risk operations from anywhere without sitting at the terminal.
