"Intercom" matching MCP servers:

Enables Claude Code sessions to communicate with each other, allowing discovery, messaging, and synchronous queries across sessions.

Enables real-time messaging between Claude Code instances, allowing agents to send, receive, and reply to messages instantly via file-based communication with auto-notification.

Relays messages between two Claude Code sessions running on separate machines, using the Channels API to push an incoming message directly into the other session so one session can ask another about its own checkout. Each message carries an id and is tracked as sent, delivered-to-process, or answered, with a per-message reply budget.

MCP server that exposes intercom tools inside Codex sessions, enabling discovery and messaging with other local coding agents (Pi, Claude Code, OpenCode) through a shared broker.

Enables local messaging between Claude Code, Codex, Pi, and other coding-agent sessions on the same machine, allowing them to discover each other, send updates, ask questions, and reply.
