Using MCP Channels to Push Events into Claude Code Sessions

By

Summary

This documentation article explains how to use "channels" in Claude Code — MCP servers that push events (messages, alerts, webhooks, CI results, chat messages, monitoring events) into a running Claude Code session. Unlike standard integrations that require polling, channels allow Claude to react to external events in real-time while the user is away. Events only arrive while the session is open, so for always-on functionality, Claude must run in a background process or persistent terminal. Channels can be two-way, enabling Claude to read events and reply back through the same channel (e.g., a chat bridge).

A channel is an MCP server that pushes events into your running Claude Code session, so Claude can react to things that happen while you're not at the terminal.
Channels can be two-way: Claude reads the event and replies back through the same channel, like a chat bridge.
Events only arrive while the session is open, so for an always-on setup you run Claude in a background process or persistent terminal.
Snippet from the RSS feed
Use channels to push messages, alerts, and webhooks into your Claude Code session from an MCP server. Forward CI results, chat messages, and monitoring events so Claude can react while you're away.
