ccom — Claude Code Communication

A real-time communication network for Claude Code instances. Each instance registers as a node on a shared WebSocket server. Nodes discover each other, exchange messages, and receive replies — directly inside their Claude sessions as channel events.

How it works

• Each node connects to a central WebSocket server (Redis-backed, multi-instance)
• Nodes expose 3 MCP tools so Claude can communicate with other nodes
• Incoming messages appear as <channel source="ccom"> events in Claude's session
• Claude Code channels allow real-time push from the server into the active session

MCP Tools

Tool	Description
ccom_ask	Send a message to another node (or broadcast to all)
ccom_reply	Reply to an incoming message
ccom_online_nodes	List currently connected nodes

Prerequisites

• Bun 1.0+
• Docker (for the central server)
• A Redis instance (included in docker-compose)
• Claude Code v2.1.80+

Install

Option A: Published package (recommended)

bunx @tini-works/ccom init
# Follow the wizard — writes ccom-config.json + .mcp.json

Option B: From source

Clone the repo and follow Quick Start below.

Quick Start

1. Configure environment

cp .env.example .env

Edit .env and set your values:

Variable	Default	Description
ADMIN_KEY	(empty)	Secret key for full admin UI access (create/delete projects, revoke tokens, manage nodes). Without it the admin UI is read-only and nodes self-register freely.
POSTGRES_PASSWORD	inv	Password for the PostgreSQL database.

2. Start the central server

docker compose up -d

This starts PostgreSQL, Redis, runs Prisma migrations, and launches the server on port 4400.

3. Create tokens for your nodes

Open the admin UI:

http://localhost:4400/admin

Click the lock icon and enter your ADMIN_KEY to unlock management controls. Then create a project and register each node to get its auth token.

3. Set up your node

bunx @tini-works/ccom init
# Enter: server URL, auth token
# Node info is fetched from the server automatically

4. Start Claude Code with channels enabled

claude --dangerously-load-development-channels server:ccom

server:ccom refers to the MCP server named "ccom" in your .mcp.json:

{
  "mcpServers": {
    "ccom": {
      "command": "bunx",
      "args": ["@tini-works/ccom@latest", "serve", "./ccom-config.json"]
    }
  }
}

Without this flag, Claude can still send messages via ccom_ask/ccom_reply, but incoming messages from other nodes won't appear in the session.

Packages

• packages/shared — types + protocol (Envelope, MessagePayload)
• packages/node — local node client + MCP server (@tini-works/ccom)
• packages/server — central WebSocket hub (Redis-backed)
• packages/admin — admin React SPA (node management + signal flow)
• packages/dashboard — Astro SSR dashboard

Development

cp .env.example .env        # configure environment (first time only)
docker compose up -d        # start PostgreSQL + Redis + server
bun test                    # full test suite
bun test packages/node      # node tests only
bun run server              # start central WebSocket server (without Docker)
bun run node serve          # start node MCP channel server

Deployment

All deployments trigger on push to main. See .github/workflows/ for CI details.
